Accessories Emergency Power from AA battery

[Mike777]

Hi all

Often I run out of power on my HTC desire and I am very tempted to buy one of these for an emergency.........

Battery Powered Emergency Mobile Phone Charger : Accessories : Maplin

Any idea if they are any good or other recommendations for emergency power ?

Many thanks

Regards

Mike

They're supposed to be alright. Apparently you can get quite good mAh out of some AA batteries.

Better check whether the supplied connectors will include a Desire one. Doesn't seem so by reading.

I keep an Eneloop AA Mobile Booster (I think that's what they call it) in my work bag at all times with 2 Eneloop AA batteries... The beauty of that one is that it simply has a USB port, so you can charge any device that has a USB charge cable (Phone, DS, etc...).

It is the first one in this list, but I'm not sure in which countries it is available (bought mine in Japan):

I got 2650mAh energizer rechargable AA's, would make a decent backup battery pack.

Never used one of those, however i do have a Pebble which i use nearly everyday for a last minute charge for both my Desire and Mp3 player (non ipod!!!!) and can not rate it highly enough.
Comes iwth loads of different connectors and recharges my desire 4 times on average between charges itself.

Submitted a question asking if it supports Micro USB.

given that this is now the standard, you would hope it does.

Ok they answered my question. It does not come supplied with Micro USB connector.

I once bought a multi USB cable from carphone warehouse which had a mini B to Micro USB adaptor. It was cheap as hell and didn't last long, but it would work in this situation.

Dry battery cells have 1.5 V per cell, rechargables only 1.2. Well fully charged they can reach 1.4, but that goes down to 1.2 quite quickly. There are applications where rechargables are not appropriate, for example those tiny cheap helicopters which are charged directly from the batteries in the infrared control. Better test your rechargables whether they work for your emergency charger.

I just bought something called "Battery backup" by a company called Signalex. It's a small, plain black plastic box that holds 4 AAA batteries and connects to my Desire via a USB cable. It charges the phone, but I haven't properly tested it yet for how long it takes or how many cycles I get from one set of batteries. I'll give it a whirl if anyone wants me to post my findings though.

The best bit is that I paid
