I want to use a dual USB car charger to run the Axim and the BT GPS Unit.

Is this any good or can you suggest something else?

I need it to power and Ever More BT GPS receiver and also my Axim X50v.

Many Thanks in advance,

There are 2 issues:

1. Powering X50v through USB is a big problem though with proper/right cables it is OK.
2. X50v needs a high current if the battery is near empty. 850mA is barely enough to do it but it is OK, IF it can output what it say it can (850mA). But very often cheap car USB chargers output a lot less than indicated.

Search the relevant inforation on Axim dedicated site.

It is difficult to see what type of connectors are fitted to the output of the E-Bay charger, the output voltage is fine at 5V but the current is 850mA, fine, if that is available to both outputs, but it is a little low if its supplying both (425mA max each) - you will find the Dell needs more than that to charge and be powered up running navigation software.

To be honest if both your devices came with car charger leads I would consider one of These and use the correct lead for each device - Mike

This applies to most chargers being manufactured and supplied down to minimum cost, most laptops will not charge if used constantly when trying to charge from a flat state, they rely on an average between max and min use, I dont think any manufacture allows for constant max power consumption.

I can only speak of my own experience, 2 out of my last 3 laptops suffered this, and admittedly subject to the intensivety of use and disc drive, also agree entirely with your sentiments on non-volatile memory with mio now being over 2yrs old and the battery life being somewhat less than usual, it is a worry when being away from home.
