High Power 10400mAh Dual USB Emergency Charger – Review

Manufacturers have been working constantly to improve their Smartphones and Tablets in order to better their offerings from the rest of the crowd. High resolution displays, bleeding edge processors, improved camera sensors are few of the vast features that devices these days must have in order to make a name for themselves.


But one aspect where manufactures are lagging behind considerably is battery life. Smartphones hardly last for a full day use while tablets can last for a day or two. And this is when Kit: High Power 10,400mAh Dual USB Emergency Charger comes in handy.

The massive High Power 10400mAh Dual USB Emergency Charger delivers more than 5 charge cycles for your smartphones while 2-3 cycles for your tablet. Retailing for £29.99, this battery pack provides dual USB output and is compatible for charging any USB compliant device.


The design is quite minimal to look at. It resembles the set-top box, only smaller with glossy curve finish at both ends while the top and bottom surface is matte. On the top, there is a power button to initiate the charging accompanied by small LEDs to indicate the charge level of the device.

The front of the device features a Mini USB port to charge the device whereas the back houses two full sized USB ports, one of 1000mA and another of 2100mA .


This allows charging of two devices simultaneously as much as two tablets. While the offering is quite good, inserting two USB cable at once is a difficult task as the other one gets disconnected easily. I would have liked the USB slots to be featured on either sides of the device than the back.

The charger is on the heavier side compared to similar other products but considering its high capacity, it’s something we would not mind to carry around.

Real-life usage

Most of us love traveling and a device like this becomes quite important when a wall socket or a charging port is not readily accessible.

While charging the Samsung Galaxy S4, I was able to get five full-charge cycles before the indicator LEDs turned red in the device. The S4 was full charged from 15% in just 2 hours and the device itself took only eight and half hours to charge from the main adapter. This is better than some of the more expensive device on the market right now.


To charge the Kit: High Power 10400mAh Dual USB Emergency Charger, you can simply plug it into your laptop or a desktop via the USB to Mini USB cable and the charging begins without having to reach for the main adapter.

You can use this battery pack with any device including top smartphones like iPhone 5s, Galaxy S4, Galaxy Note 3, Sony Xperia Z. This is one of the must have emergency charger in your Sony Xperia Z1 Compact Batteries collection.

In the box

After spending £29.99 for the device, you will get a 10,400 mAh charger along with 3 interchangeable charging adapters, a Micro USB, Mini USB and 30 pin charging adapter.



For a frequent traveler, the Kit: High Power 10400mAh Dual USB Emergency Charger is really a nice device to have. It will charge your smartphone or tablet quickly and simultaneously which enables you to check your important emails or social updates on-the-go. The only complain I have is the close placement of the two USB ports at the back but it is not a deal breaker by any means.
