Batterytec 4000mAh Power Bank Review

The Batterytec 4000mAh power bank sells itself as a portable, super slim charging device for your smartphones. It sure is a beautifully designed battery pack, neatly resembling my 4th-gen iPod Touch with a shiny metal rear. Slim it is too, being only marginally thicker than my iPod Touch.

Before opening it, it was preparing myself to be bitterly disappointed. Most 4000mAh battery packs are very small, compact and portable – however in the box this was looking much larger than it’s competition. However, after opening the packaging, it is safe to say that it is very small and compact and easily fits into a small pocket.

Features:

  • Universal compatibility with USB output port
  • Super slim design
  • 4 LED charge indicator

With 4000mAh of juice this battery pack is able to charge your iPhone 5S from flat to 100% three complete cycles before requiring a recharge. For shorter trips and journeys, this is a great addition to your travel kit – and it’s design and size make it suitable for slipping it into your pocket for college or work too!

Batterytec 4000mah Power Bank 2

As long as the device you wish to charge is compatible with a USB cable (which almost all devices today are) you’ll know that the Batterytec 4000mAh power bank will charge your device.

However, since this is a power bank with a smaller capacity; output is restricted to 1A so charging tablets and more power-hungry devices that require 2A will take a painfully long time. This also rules out compatibility with some Kindle’s and tablets which will not charge with an output of less than 2.1A.

Overall, if you are looking for a small, stylish and well thought out battery pack to give your smartphone extra juice I would thoroughly recommend the Batterytec 4000mAh power bank!
