Lumsing Mini 3000mah Ultra-compact Portable External Battery Backup Power Bank

This Lumsing power bank batteries comes nicely boxed and is very compact but still manages to provide 3000mAh. In terms of size it is a little bit bigger than a lipstick and beautifully crafted – it measures 3.7” long and is square in section, albeit, with nice rounded corners and each side measures 0.86” with the whole device weighing just over 2.5ozs. In the box you get the power bank with a neat Micro USB lead which doubles for charging the device as well as connecting to a lot of smartphones, plus instructions, warranty/support details. If you want to charge an Apple device you'll need the appropriate lead.

The exterior finish is mainly coloured aluminium that looks very chic with white end panels. The top end panel sports a full size USB port with a standard 5V 1A output plus a Micro USB socket for charging. On the side is an on/off switch and a 3 LED charge/charging indicator - when the battery senses no load it switches off automatically. There is also a small LED torch facility built into the front panel which will certainly help you locate your keys etc. The device features electronic charging/short circuit protection etc. plus uses a Samsung power cell sio it should be safe and carries FCC, CE and RoHs approval marks. The unit takes around 2.5 hours to charge from flat .

 In use the power bank is easy to use and despite its modest size it will recharge an average smartphone nearly twice but rather than a charge from flat, if your battery is running low, it will prolong your usage of the device itself considerably. In the case of a tablet it will extend the usage time or charge it a bit but obviously not to full capacity. I tested it with an iPhone, Nokia Lumia 630 Smartphone, Samsung Galaxy Tab 3 (7”) and it worked very well with all of them.

 Because of its compact size, chic look and reasonable output this is a mini sized external battery power bank that you are likely to have with you when you need it most, plus, it has enough power to be genuinely useful - I like it a lot. Recommended.
