What is a Power Bank?

A Power Bank is a portable mobile charger that you can charger your mobile phone anytime anywhere without the presence of a socket. You do not need to worry that your cellphone is power off, or search for a socket when you are traveling or out for business. And it is only the size of a cellphone, so small that you may slip easily into your pocket, on your key chain, or hold it in your hand.

How to use a Power Bank?

Firstly, make sure that the power bank is full charged. To charge a power bank, you just need to connect one side of the data cable with your cellphone charger or any computer with USB port, and plug the other side to the power bank where marked “IN”. When the power bank is full charged, then you can charge your cellphone. To charge your cellphone, connect one side of the data cable with your cellphone, and the other side to the power bank where marked “OUT”. When charging is done, remove the cellphone and the data cable.

How long should I charge my power bank?

It depends on the capacity of your power bank and the output current of your charger. For example, if the output current of a charger is 1000mah, while the capacity of the power bank is 5200mah, then the charging time is 5200mah ÷ 1000mah= 5.2 hours. If the output current of your charger is less than 1000mah, then the charging time might be longer. 

Will Your USB Flash Drive work with any computer?

Yes, all our USB Flash Drives operate with all PCs or Macs manufactured in the past 10 years as long as they are equipped with USB ports and operating system capability. 

Why my USB shows less capacity than it should be?

It's because for hardware manufacturer 1k=1000bytes. But for Microsoft 1k=1024bytes. That's why a USB drive 512MB shows only 499MB under Windows OS.

 What is the difference between USB 2.0 and USB 3.0 ?

 The main difference between 3.0 and the previous standard of 2.0 is that USB 3.0 drives are 10 times faster in Reading and Writing. As USB 3.0 chips are costly, USB 3.0 drives are much more expensive than USB 2.0 drives.

How much do Flash Drives cost?

Prices are based on the capacity of the Flash Drives you order, the amount of Flash Drives you order, and the method and amount of colors your logo imprint will use. Services such as graphic design, pre-loading/auto-run, and customized packaging will incur additional costs. Please contact your Account Manager for the exact cost.
