Bests & Worsts Reviews from Amazon

I just received my IMP1000 from New Trent earlier this week. I was looking for a reliable way to easily charge my iphone and ipad when traveling, especially on long flights. This seems to be the device to bring along. I recently flew overseas with their IMP880 and it performed wonderfully. I was looking for a bit greater capacity though, because I use both an iphone (was the 3g, now the 4) and the ipad, and wanted to be able to charge both of them when I don't have access to an electrical outlet. The unit's size is great for traveling. It's about the same size and weight of a portable hard drive, which these days means it's small and will easily slip into a briefcase, overnight bag, purse, etc. The retractable cord makes it easy to hook up with the mobile device without any strain on the connections. The unit's indicator light is simple to see and determine the amount of charge remaining. While charging the unit itself those lights let you know the progress. And after charging a mobile device, the unit slows down to a trickle charge. The placement of the button is an improvement over New Trents IMP880, which I also own. That button could accidentally be turned on because it actually protrudes a bit from the case, and sits at an angle. The IMP1000's is flush with the case's edge, and the button itself a bit recessed which should prevent that from happening. I haven't drained the power from a full charge yet, so not sure how long it lasts, but after topping off my iphone and ipad a few times, it still shows a full charge. Of course you can use the device while it's charging. The IMP1000 comes with iphone/ipad adapter, along with a few others (mini usb, etc). Good design, seems well built, and I know from past experience with New Trent's customer support that they are very responsive. Recommend you give it a try if you need a back up battery.
