Yes, this has to be the coolest rechargable battery that I have ever seen. I can’t wait to purchase a few of these. Don’t know how long we have to wait as it looks like you can only purchase these in the UK right now. But I am pretty sure we will start seeing these in the US and across the world soon as this is the coolest way to use and re-use as the charger is built into the battery itself. The only draw back I see but it really is not that big of a deal is that the battery only is a 1300ma battery. Where a lot of the newer rechargable batteries are 2300ma – But they all require you to have a battery charger with you to charge them. This little battery only requires you to pop the top and plug into the usb port and charge away. They can even plugged into a usb hub. or anything that outputs the 5v required to charge it. They are like any other battery the charge time takes about 5 hours for a full charge from a totally drained state. But you can plug them in anytime to get them back up to life. Plus these are NiMH Batteries and don’t have the “Memory” issue that older Rechargable batteries have.
