Duracell Powermat Portable Battery with up to 100% Extra Battery for Android and iPhone 4/4S -Black

Recharges via Powermat wirelessly although it is slow. The first charge this way wasn't working properly and I had to charge it multiple times before it reached full capacity. The device does work fine as a power bank with the two connectors. However, the capacity is low at under 2,000mAh. The device is rather old as it has a 30 pin Apple connector which is obsolete and only useful if you have older Apple devices. The MicroUSB is the more useful of the connectors. Despite the age and finicky charging, it does work and the price is very low. It's actually quite neat for the price and the wireless charging capabilities makes it very unique. It's a great addition if you already have Powermat devices for the novelty of wireless charging. Otherwise, it's nothing worth getting. You can easily find power banks around this price with 2x the capacity, some with 2A outputs for faster charging.Update: The device is proving to be unreliable. It will work well sometimes, showing proper charge level with LEDs and other times, it doesn't work at all; no LEDs and no power despite it being fully charged. Sometimes, it won't charge up at all. Occasionally, it comes back to life through pass-through charging (charging something via the portable battery while it itself is getting charged). I find that using the USB cable is more reliable than the Powermat to revive it. Either way, it's unreliable and probably due to the age of the device (it probably sat in a warehouse for several years before getting sold and I think the battery is shot from age). In all honesty, it's a device you should avoid. It's outdated, unreliable, and you can do better for the same price with other power banks.

Pros: you can charge this on a wireless charging mat - which is very convenient. The attached multiple cords are nice. It comes with a short USB cord so you can charge it that way, too.Cons: It will not charge your device wirelessly - so if you bought this, like I did, for a phone whose charger port is loose and doesn't work - you're going to be disappointed.

Does not come with a charging cable and a regular usb does not work. Also does not charge a c type. So it's worthless to me. Bought it with the powermat but that won't charge my kyocera.

This thing is awesome. I bought for my daughter and she offered to lend it to me for a road trip I took. We both thought it world need to be charged because it sat unused for awhile. We were wrong it still had a complete charge.The only down side is that I have to remove my otter box to use it

It's really good, it's small and the charges are good, recommended
