SWPKPOWER SW-A44920 Portable 5200mAh Battery w/ 5 Adapters - Black

Pros: - It features a digital display which shows the remaining capacity of the portable battery. - It comes with a mini LED torchlight. - Can be used for different phones as 5 different adapters have been provided. - It is small and compact. - Great build quality

Cons: No cons have been found after using it for almost a month now.

Other: A very handy charging device or as a back-up power source. Highly recommended, specially if you travel a lot or if you are a heavy phone user.

Pros: I have ordered two other types of Portable Batteries over the past two years from DX, three batteries in all, two of them could be fully charged, but had no output on the USB Connector. So this order was my last attempt at getting a working model. I was not disappointed, this Battery Pack is compact in size and has more than enough power to keep my devices working for a very long time. A great plus is the Digital Display which works very well. Like most Portable Battery Packs this also comes with a good selection of adapters, but like most others a 2.5mm adapter is missing from the otherwise good selection. It also come with a USB extension cable, which is very useful, so you do not need to have the Battery near your device.

Cons: I can find no cons whatsoever.

Other: It has taken me quite some time to find the right model, that actually works all the time. So my search is now over!
