I purchased this power bank by #TopMate for a good friend of mine. This friend is pretty much technologically challenged, so I needed something very basic for her to use to charge her phone. This one definitely does the job. It has 10000 mAh and so it can charge a few times before you need to recharge the powerbank itself. I like the built in cable feature so that she doesn't have to bring her own cable. The cable that doubles as a lanyard handle makes it easy to carry on your fingers but it won't fit around your wrist. It's too small for that. I also like the 4 lights that let you know how much power is left as each blue dot represents 25% power. All 4 dots lit means that this power bank is fully charged and ready to be used. This powerbank can be used on both Android and iOS phones so it can b ed the perfect gift especially for those that like the very basic types of accessories. My friend is very pleased with this powerbank and its simplicity.
