Frequently Asked Questions

There is no need to spend extra time in charging  or charge it after discharging off all electricity for the first time.

Most power banks have a built-in four LED lights indicator. After recharging mobile devices, please check how many LED lights illuminate to know the remaining power.

ACT  power bank supports charging most of different digital products including smartphones, MP3s and MP4s. Please refer to the specification before purchasing and charging.

Yes, most of our power banks can be charged and charge other mobile devices at the same time. It varies with different product models and depends on how many outputs the power bank has.

Power banks work with all brands and models— Android, Apple, whatever.
Smartphones require a capacity of 2000 – 4000 mAh
Tablets need between 4500 and 10400 mAh

The charge speed depends on the output current (1A, 1.5A, 2.4A.) The higher the A, the faster the charge. A larger mAh won’t charge your device faster, but a larger A will. If the 2200 mAh and 4000 mAh power bank both have an output of 1A, the time it’ll take to charge your device is the same.

USB Company products are based on the USB standard and operate with all PCs and Macs and devices with a USB port and running Windows ME or later or Mac OS 8.6 or later. (USB drivers are also available for Windows 98, Windows 98 SE and Windows NT).

Using a flash drive to store files is just as easy as using an old floppy disk and even simpler than burning a CD or DVD. Just plug your Flash Drive into a USB port on your computer and drag the files you want to take with you into the folder that appears in “My Computer” or on your desktop. Your files are quickly copied over to your Flash Drive. To transfer the items on your USB flash drive onto another computer, simply plug your Flash Drive into the new computer, open the folder that appears on your screen, and drag the desired files onto a folder on the destination computer.

Flash Drives are currently available with up to 64GB in storage capacity and are available in a variety of storage sizes for different needs. For reference, a 4GB Flash Drive can hold about 500 songs in MP3 format.

USB ports are much more common than DVD burners so while your Flash Drive will work with almost any computer, blank media (CD-R, CD-RW, DVD-R, etc.) would require the hardware necessary to write data to them. Also, the process of copying files from your computer to a Flash Drive is much faster and simpler than burning a CD or DVD. What’s more, Flash Drives act like portable hard drives to which you can add and delete files as many times as you like-as opposed to CD-R’s and DVD-R’s where you can only add data once and you cannot remove data once it is burned onto the disc. Also, unlike blank media which are sporadically faulty and deteriorate consistently over time, Flash Drives are manufactured and printed under rigorous quality control standards.
