    • What Are Power Banks and How Do They Work?

      Even if you don't know what a power bank is, chances are you've used them, own them, and rely on them on a regular basis. So, just what is a power bank? Our promotional power banks are devices that are used to charge mobile devices such as smartphones, tablets, and MP3 players. All of our promotional power banks are equipped with either lithium-ion batteries or lithium polymer batteries and are housed by protective casings.

      They connect to other devices by way of USB cables which are connected to the power banks' output ports and the input ports of the devices being charged. Electricity flows in a current from the power bank battery, through the USB cable, and to your device to keep it running at top power. They're especially handy when there are no available wall sockets to plug into or all of the outlets on a power strip are already occupied. Their modern convenience is yet another reminder of how far away we've moved from the obsolete tech items from the 90s. Whether camping, commuting, killing time in a waiting room, or marooned in any other place where power outlets aren't readily available, our custom promotional power banks will make sure that your mobile devices and those of your employees & target market stay up and running!


      Promotional Power Bank Components

      Our custom logo imprinted power banks have pretty self-explanatory structures, but some of the words used to describe them can be a little confusing if you don't either produce or sell power banks for a living. In order to make our individual promotional USB power bank product descriptions less frustrating and more useful, we'll now explain to you some of the most important components of a typical power bank.


      Promotional Power Bank Batteries

      Our promotional power banks, as well as just about anyone else's, will almost always contain one of two battery types. Because both of these battery types go by so many different names, it's easy to get the impression that there are several more. Fear not though, because we will share the alternate names with you and by the time you finish reading this section, you'll have become promotional charging bank battery pros.


      Lithium-Ion Batteries

      The first and more common variety of power bank battery we'd like to introduce with you are Lithium-ion batteries. As we said before, our business logo power bank batteries possess a king's ransom of nicknames. You'll also see Lithium-Ion batteries referred to as Li-Ion batteries, LIBs, and USB batteries. The last term is actually incorrect; USB batteries do exist, but refer to something else entirely.

      Lithium-ion batteries are lightweight and rechargeable. They also offer an impressive amount of power and stamina for their size. However, they are not immortal and as with any other battery, they eventually will weaken and ultimately stop working after too many re-charging cycles. No need to fret though, as this won't be an issue for a long time. These batteries work by way of moving lithium ions through their inner membranes toward the cathode or + side of the battery. This flow of electricity toward the cathode (the other end of the battery being the anode) enables electricity to flow throughout a device to maintain a steady source of power.


      Lithium Polymer Batteries

      The other type of battery you'll find in our power banks are Lithium-polymer batteries. These are also called LiPo, Li-Poly, LIP, or rechargeable polymer batteries. While they are similar to Lithium-ion batteries, they are not exactly the same, despite what some sources may tell you. Lithium-polymer batteries are generally a bit larger than Lithium-ion batteries and usually have higher capacities in terms of mAh. These batteries are especially helpful for power banks that need to charge larger devices such as tablet computers.

      When you see the term "Grade A" before any of our custom power bank batteries, it means that the battery has a capacity of 1000 mAh or greater. If you're unfamiliar with terms such as capacity and mAh, fear not. We're going to explain them in just a bit.


      Promotional Power Bank Input Ports

      Most any item that operates in conjunction with USB cables will have input and output ports. It's easy to visually distinguish an input port from an output port. Input ports are generally quite small and have a trapezoidal kind of shape. In our promotional battery power banks, the input port is where the power bank's own USB cord will be attached to a wall socket to charge its batteries. The energy that flows into a power bank through its input port is measured in volts. Voltage is also used to measure the energy level at which the battery operates. Most all Lithium-ion charger batteries naturally run at a voltage of 3.7, but can adapt to run at 5 volts while in use.


      Promotional Power Bank Output Ports

      The output ports in our promotional power banks are larger than the input ports. They also have a typical rectangular shape. These are the ports you would use to connect to the device that you're wishing to charge. When the USB cable is in place to connect a power bank to a phone or tablet, energy flows out from the power bank's battery and is measured in amps. Most smartphones and MP3 players only need 1 amp to efficiently charge, while tablets usually will require 2.1 amps.

      The pressure with which the amps flow to your device is measured in volts, so when you see a power bank with a battery rating of 5V/1A or 5V/2.1A, it means that the battery is operating at 5 volts and that the device is pulling 1 amp or 2.1 amps of electricity, respectively. Because of this, we offer many promotional power banks with multiple ports so that the same custom power bank can charge both your phone and your tablet.

      You can think of it as a push and pull kind of relationship. The power bank battery pushes energy out in volts and the mobile device being charged pulls in energy in the form of amps. As we said, a typical smartphone or MP3 player only requires 1 amp to effectively charge, but you can also charge them at 2.1 amps if desired. The result is a faster charge. Some devices will only accept a certain level of amperage and will self-regulate to only take in 1 amp while charging. Even if this isn't in place, you don't have to worry. You'll only run into problems if you try to charge a device at a lower amperage rate than what is recommended.


      Custom Power Bank USB Cables

      In order for our custom business logo imprinted power banks to effectively charge any device, a USB cable is needed. USB stands for Universal Serial Bus and the main function of these cords is to transfer data and power from one source to another. Consistent with the ports that they populate, every USB cable has an input and an output. The input (also known as the "upstream connector" or "Type "B connector") is the small trapezoidal end and the output (also referred to as the "downstream connector" or "Type A connector") is the larger rectangular end.

      The input connector of a USB cable goes into a device that is being charged and the output connector goes into the host device, or the entity that is providing the charge. For example, picture your cell phone. You know that when you charge it, there's a small port that a small USB connector enters. This is the input connector. You also know that a larger, rectangular port exists in your charger, and this is the output connector. Your phone draws energy from the host device by way of the output connector. The energy then flows through the USB cable and up through the input connector and into your device.


      Promotional Power Bank Materials

      Our custom power banks for businesses are constructed of a variety of different materials, each with its own advantages and unique properties. The best material for a power bank all depends on your business's particular promotional needs and requirements.


      Plastic Power Banks

      Many of our more affordable power banks are constructed of plastic. Our plastic promotional charging banks are lightweight and easy to transport. Two of the most common plastics that go into the construction of power banks are ABS plastic and EVA plastic. ABS (Acrylonitrile Butadiene Styrene) plastic is known as a thermoplastic. This is because it isn't destroyed by heat - it's highly malleable and can be melted down and reformed into nearly any shape over and over again without losing its integrity.

      All told, it's pretty much the ultimate in recyclable plastics. It's also inexpensive, surprisingly sturdy, and resistant to impact and most chemicals. It's seen in many items that you use every day. One example would be the keys on a computer keyboard, which are almost always made of this kind of plastic. Our custom ABS plastic power banks are among our most affordable models and are great when buying power banks wholesale.

      EVA (Ethylene Vinyl Acetate) plastic can exist in many different forms. Despite being highly elastic and rubber-like, it can be compressed into hard, rigid forms as well. When existing in this form, EVA plastics are typically used to provide sturdy and reliable protection, usually beneath other materials. Rather than being used in the devices themselves, EVA plastic is seen in many of our promotional power bank carrying cases.


      Metal Power Banks

      Many of our high end promotional power banks are made of metal, particularly aluminum. Our business logo aluminum power banks come in a few different forms. Some of our power banks feature aluminum alloy construction. Aluminum alloys consist of aluminum combined with metals such as copper, magnesium, zinc, tin, and manganese. These bolster the aluminum with additional strength for greater resistance to corrosion. We also offer personalized power banks made of anodized aluminum. Anodized aluminum is treated by way of being immersed in chemical coatings which provide an even higher level of protection against rust, abrasions, and smudges. Our company branded stainless steel aluminum power banks are among the toughest models money can buy. They offer ultimate durability with a powerful, modern look.


      Bamboo Power Banks

      Our promotional bamboo power banks bring together rustic charm and cutting-edge technology in a single product. Quality construction and impeccable visual design make these some of our best-selling power banks for businesses.


      Power Banks with Protective Epoxy Domes

      Many of our promotional power banks have protective epoxy domes. These domes consist of thick layers of liquid adhesive which are applied at the surface of the area where your custom business logo is printed. It provides a 3-dimensional look and protects your logo from being scratched, smudged, or fading over time.


      Promotional Power Bank & Custom Phone Charger Terminology

      Our custom logo imprinted power banks and promotional phone chargers probably have more technical and in-depth descriptions than any other class of items on our site. Therefore, it's natural that many people won't be familiar with a lot of what they read on our product pages. In this section, we'll provide some definitions for some of the more often-seen terms on our individual power bank product pages.


      What is Battery Capacity?

      Battery capacity is something that you'll see mentioned in every one of our individual power bank descriptions. This is because it's quite possibly the most important statistic you'll need to know in order to decide which one of our wholesale business logo power banks best fits the promotional needs of your business. To put it simply, a power bank battery's capacity is a measure of its longevity. In other words, it lets you know how long you'll be able to use a power bank before its batteries will need to be recharged. It also helps you to know which devices a given power bank is able to charge.


      What Does mAh Stand for?

      The battery capacity in our promotional battery banks is measured in mAh. These are milliamp hours, though mill-ampere hours and milliampere hours are also commonly used terms. A milliamp is one thousandth of an amp. As stated earlier, amps are the units of energy which devices pull from power banks in order to charge their own batteries. If a battery has a capacity of 2000 mAh, that means it can consistently provide 2000 milliamps, or 2 amps of energy, for one full hour at a time at a specific voltage before it runs out of energy and needs to be recharged. Nearly all power banks run at 5 Volts, so that's a number than can always be assumed.

      A higher capacity means that a battery is able to provide more energy for a longer period of time. Even if you no longer have the manual that came with your phone, tablet, or iPod, you can still look online to see what the capacity of its battery is and therefore know how much energy it needs to be fully charged. It's a whole lot easier than opening the device up and extracting the battery to read its specifications.


      What are Amps?

      Amps, short for amperes, are a unit of measure for the volume of electrons passing through a wire in one second. Basically, amperage refers to the energy a device is drawing from a power bank and how quickly it is doing so. It's the current rating for a battery's output, and shouldn't be confused with the mAh number, which, as we said earlier, is a measure of the battery's longevity.


      What are Volts?

      Voltage is a number that remains at a constant. It's a measure of the electrical pressure and strength of current being pushed from an energy source. In this case, of our promotional power banks, it concerns the level of electrical pressure the power bank's battery is running at to push energy toward its output port and connected device. The input voltage of a power bank's battery refers to the voltage supplied by a grounded electrical outlet that a power bank is plugged into while being charged.


      What is SmartSense?

      SmartSense is a technology used by our power banks that allows them to identify and properly charge mobile devices.


      What is Standby Current?

      Every battery, regardless of what kind it is or what it is being used for, consistently leaks energy at all times. Standby current is the number used to measure this energy leakage, particularly when a battery is not being used. It's also known as quiescent current. One shouldn't be overly concerned with this number, as the standby current rates for our promotional power banks are extremely low. They're so low that they're measured in microamperes, which are equal to one millionth of an amp. The amount of time that a charging bank's battery can lie dormant before needing to be charged again is known as its standby time.


      Promotional Power Bank Certifications & Approvals

      Mobile technology, for better or worse, is becoming an ever-growing part of our lives. Consequently, it is important that they are functional at all times. This means that our promotional power banks need to be efficient, reliable, durable, and environmentally-friendly. For all of these reasons and more, there are several different standards, certifications, and approvals that a power bank needs in order to be sold, though requirements do vary by geographic location.


      CE Approved Power Banks

      CE stands for Conformité Européenne. Since 1985, this organization has set the standards for requirements a product needs to meet in order to be sold in Europe. It is most commonly seen with electronic items and centers around quality and safety.


      FCC Approved Power Banks

      The Federal Communications Commission is a United States government agency that you've likely heard of before. Rather than dealing with censorship, the FCC regulations pertinent to our promotional power banks are in place to ensure that they operate within frequencies that won't interfere with the electromagnetic currents needed for radios, television, mobile devices (kind of ironic), and satellites to operate efficiently.


      MFi Certified Power Banks

      MFi is a set of standards maintained by Apple. It stands for "Made For iPhone/iPad/iPod" and it means that a given peripheral device is compatible with and well-suited for these products. We provide several MFi certified promotional power banks for iPods, MFi certified promotional power banks for iPhones, and MFi certified promotional power banks for iPads.


      IEC Certified Power Banks

      The IEC is the International Electrotechnical Commission. It's an independently-run organization that has no connections to the government of any one nation. Essentially, IEC certified power banks are power banks that live up to what they claim to be. In other words, an IEC certification guarantees that a product has the qualities and capabilities that it is said to have by its vendors.


      RoHS Compliant Power Banks

      RoHS is an acronym for Restriction of Hazardous Substances. The goal of its relevant standards is to ensure that technological products are produced with as few hazardous substances as possible in order to prevent pollution, environmental damage, and health risks. You can rest assured that our RoHS Compliant power banks are eco-friendly promotional products.


      UL Listed Power Banks

      UL is an acronym for Underwriters' Laboratories. The UL is a worldwide safety and health assurance testing organization. While it is an independent organization, it is approved to conduct safety and quality testing in the United States by OSHA, which is the Occupational Safety and Health Administration.


      Promotional Power Bank Styles

      We offer power banks in a cornucopia of different shapes, styles, sizes, and functions. We have a custom logo imprinted power bank to your promotional needs, no matter what industry your business operates in. Read on to learn a bit more about some of the different types of promotional power banks we offer.


      Credit Card Power Banks

      Our promotional credit card power banks are extremely thin and compact. They get their name both due to the facts that they have a similar shape to credit cards and that they're designed to fit within the credit card slots of a typical wallet.


      Solar Power Banks

      Our business logo imprinted solar power banks, as one would expect, are solar powered rather than reliant upon electricity for charging purposes. They're among our most eco-friendly power banks and many feature batteries with significant capacities.


      Power Sticks

      Our rectangular custom battery banks are often referred to as power sticks. A promotional power stick offers a familiar shape and a body that's easy to store and transport wherever you go. Many of our power sticks fit within the pocket category.


      Pocket Power Banks

      Promotional pocket power banks are relatively small and easily can fit in one's pocket. Therefore, it's no mystery as to how they got their name. Many people associate pocket power banks with low battery capacity, but there are some pocket power banks that are able to provide enough energy to still live up to the "power" part of their name.


      Phone Stand Power Banks

      We offer several promotional phone stand power banks. These power banks come equipped with suction cups, or suction feet if you will, to which you can stick your phone to during charging cycles. They're a handy way of keeping your items organized and conserving space. They're promotional products for businesses that are definitely built with ergonomics in mind.


      Promotional Multiple Port Power Banks

      We carry a grand array of multi-port power banks imprinted with business logos. These are highly convenient promotional products, as they allow you to charge your phone and your tablet at the same time. You can also charge two phones at once, two iPods at once, a phone and a GPS while driving, and so on.


      Custom Promotional Power Bank Accessories & Features

      Who couldn't use a bit of added convenience in their life? Nobody we can think of. That's why you'll love having your business logo imprinted on our promotional power banks. Many of our custom charging banks have additional handy features and accessories that will make your employees and customers want to take them everywhere they go. Mobile advertising on a mobile device is a match made in heaven!


      Custom Power Banks with Digital Displays

      Several of the custom power banks available on our site come with digital display screens that always let you know how much remaining charging capacity is available. Our promotional Zing power bank with digital display is just one example.


      Promotional Flashlight Power Banks

      Our promotional flashlight power banks offer a 2-in-1 tool that function perfectly in automobiles, on hikes, and on camping trips. When you can't get to an electrical outlet, it's pretty nice to still have both a source of light and a power source for your mobile devices.


      Custom Power Banks with LED Indicator Lights

      Some of our promotional power banks feature one or more built-in LED lights that let you know when they're fully charged, when they need to be charged, and when they're successfully charging a tablet, cell phone, or MP3 player.


      Promotional Power Banks with Wrist Straps

      Our customers love our promotional power banks with wrist straps. While this feature may just be an afterthought for many, they go far in preventing users from dropping, losing, or leaving their power banks behind when they're finished using them.


      Additional Features

      In addition to the above bells and whistles, there are many other special items and qualities offered by our various power banks. Key chains, carabiners, bonus USB cables, slide doors, custom packaging, and carrying cases are available in several of the promotional battery banks available on our site.


      A product isn't very promotional if it doesn't include a custom printed business logo. We surely haven't forgotten this fact, as our promotional power banks come with several custom logo imprinting options to choose from. We'll explain these options to you in the following paragraphs.


      Screen Printing

      Screen printing is one of the old standbys when it comes to product promotion. It's one of the most affordable ways to print your custom business logo on a promotional product to ensure ongoing advertising wherever your items go. Many screen printed logos consist of a single color, but multiple colors are often available for an extra fee.


      If you want your promotional power bank to be custom printed with your company logo in a speedy fashion that renders bold colors, this is the method for you. Multiple colors can be imprinted simultaneously, which saves time, and as every business owner knows, time is money.


      Pad Printing

      Pad printing is a custom company logo imprinting process that is often used on items that have unusual shapes or hard-to-print surfaces. The pad printing process starts with a custom etched metal plate being coated in ink. A soft silicone pad is then pressed to the plate so that it will take on the right patterns and colors, which are then softly pressed against the item that is to bear the design. Once this is done, the ink is dried and the process is complete.


      The ColorBLAST printing process is similar to full color imprinting. It makes use of specialized inkjet printers which are able to move items as they go through the printing process. Specialty inks are applied to the surface of the items and absorbed in a way that allows for more detailed and intricate designs.


      Promotional Laser Engraved Power Banks

      For a durable, elegant, and impossible-to-ignore company logo design on your promotional branded power banks, we recommend laser engraving. Through the laser engraving process, your promotional power bank will have your custom business logo etched into its outer casing for a textured look and feel that can't and won't fade over time.


      Our Power Banks with digital reset logo imprinting feature at least two custom logo imprint areas. The reverse part of the name refers to a logo's text and background being swapped. For example, if your business logo features yellow text against a blue background, the additional digital reversed logo imprint would consist of blue text against a yellow background.
