Comments about Sony CPF2LS Portable Power Supply (7,000 mAh):
I bought this device because my devices run out of battery quickly. I was very pleased with the fit and finish, it is mostly aluminum casing with a plastic top and bottom. The battery has two 3500 mAh Li-Ion batteries that do not heat up during use, and even while charging two devices simultaneously. The two usb ports are a big selling point for me and it is handy if I have multiple devices that need to be charged. Another neat feature this device offers is its ability to charge other devices while being charged itself. If you have two devices you need to charge and only have one micro usb cable, you can plug that cable into the battery and charge the battery and the two devices simultaneously. I like that feature. So, after rambling on and on about this battery, I have to say that I highly recommend it.
