And it has an off button!

I haven't really used it much, but I'm thrilled that it has an off button, as I'll be using it to power a Raspberry PI.

Great Backup Battery!

I love this power bank. It charges really quickly and holds a lot of charge, perfect for long trips!

Well Worth

I bought this out of a recommendation from a co-worker. A great price for the product. Definitely hold a large amount of charges. I have charged my tablet, phone and headphones at the same time. It is a little bulkier than I would have like, but it is expected with it's capacity. It was appropriate to have included a micro usb cord with it, but would have rather if it was substantially larger. Hardy and useful, overall a great product.

Exactly as advertised

Exactly as advertised. Good for four charges and two devices at the same time.

nice one!

nice one! charged 4 times, 3000mha samsung phone. however it should be charged at least 5.5 times

  • from Mississauga, ON


Can't go wrong here. It's a huge battery so charge it overnight and have it ready. Charged my devices quickly too. Up to 3 at the same time. It's big and heavy but the capacity is worth the trade off.
