How to select the right mAh portable battery charger?

You are correct, and I didn't mean for my post to sound like I was discounting your comment. Perhaps you missed my comment further on... "The previous post was a good explanation.", referring you your post.....

its all gud
i tend to be more technical, what i stated was acquired from my profession and past experience.
i mainly recommended shorter charges to keep the heat and stress on the host battery at a minimum.
the benefits you stated and your link provides good reasons as well.

I ended up getting the New Trent iCruiser IMP1000 which is an 11000 mAh charger. It works great. So far I've done three charges from ~33% to 100% which have taken ~ 2hrs each (although they reach 90% in about 1 hr). There are three led lights on the charger to tell you how full it is and they are still all still lit up so I'm sure I'll have plenty of charges left.

The current model does not have two ports, one at 1A and one at 2A. It only has a 1A port, although I understand that will be changing soon. the 2A port is better for charging iPad tablets, which I don't have and don't plan on getting. However, as an fyi, the reviews I read have plenty of people with iPad 2 devices who are charging them on the 1A port without problems. But, like I say, I think they will be changing this to a two port model soon.

I'm very happy with it. :biggrin:
