Default Li-Polymer external battery charger - 01-02-2009, 09:41 PM

Hi

I wonder if you guys would mind offering an opinion on this item
http://www.my-battery.co.uk/external-laptop-battery.htm

I have been looking for a Li-ion (this is li-polymer which theoretically should be more advanced) adjustable voltage charger for use with my Mini9 and my HTC P3700 pocket PC. At first glance this would appear to offer what I wanted but I'd really welcome some advice from those of you who understand the techie stuff better than I whether this is worth considering.

I have been looking at a number of different items that vary from around £15GBP to £30 (plus a 4400MAh mini9 exclusive battery at £60) but none of them do all of the jobs I need them to do. This appears quite expensive at first glance but if it ticked all the boxes then maybe it is good value

Thanks in advance again

Alex

This item is not a charger - it is a complete external battery (with dedicated charger). That's why it's expensive. You charge the battery in advance, and then connect the battery to the "charger input" of the Mini (or whatever) to let it run from the external battery. This is great if you need REALLY extended run-times.

It doesn't sound to me as this is what you're looking for.

Looking at the listing again I'm not 100% sure one way or the other :?:

21200mAh External laptop battery pack power and charge laptop(pc) computer, cell phones, car cord

I think it will power the Mini9 without its own battery but would also charge it if it was fitted. I don't think it is exclusively an external battery. Do you think that is right or not?

Why do you specifically want "adjustable voltage"? I would think that any external power supply compatible with Dell laptops would do. The voltage and connector size is common.

I thought I had explained that in my original post but maybe I didn't make it clear enough so here goes again. I need 19V for the Mini9 and 5V for my PDA (with GPS/satnav). Here is a bit more info that might explain why I want this type of charger. I will travel with the Mini9 on my motorcycle. I deliberately bought a Mini9 for its compact size and the (more robust) SSD memory. I may not have access to a charging source and felt that this type of item would ensure that I had use of my Mini9 and PDA. Hope that makes more sense now.

Ah. Look then at one of the chargers from iGo or Kensington that have different tips and self-adjusting voltage. Some of these have USB power outputs which your GPS will use. On the other hand, a small USB power adapter and the Mini adapter together are smaller (and way cheaper) than these adjusting power supplies.
