This is it top right of page, the one on the left is the same but with various pin adaptors, The single 1amp output travel charger I already have has the pin adaptors but to be honest I find them just more bits to cart about and loose and I always have the standard travel adaptors anyway.
I did say in last post it had 2.5amp max output, sorry it is actually 2.1 amp, but read on http://www.maplin.co.uk/search?criteria=USB+Charger
I bought this Saturday afternoon in the local high street Maplins and when I posted on Sunday I hadn't had chance to try it out as I wanted to monitor its charging against the standard Archos charger as Lith Ion batteries (and the other rechargeables) will try to take whatever current you chuck at them unless controlled.
(main reason for buying besides it cutting down on number of chargers to carry about, is that I am good at loosing chargers and I would rather loose this than the genuine Archos)
Now Maplins assure me that it is ideally suited to the Archos, and they sell Archos kit, plus Maplins staff usually have quite good technical knowledge. So the way this thing is supposed to work is:- .. if just one USB devise is plugged in then 2.1amps will be available on the one USB socket in use, but if both sockets are plugged into it is supposed to automatically switch down to 1.01amp per outlet.
So, I first timed the Archos charger and it was averaging 1% of charge every 3 minutes 22 seconds. When I tried the one from Maplins I didn't get any kind of slow charge warning but then a few seconds after plugging it in the % of charge dropped down a notch, I waited 3mins 30 seconds and it didn't even go back to where it had been. I checked the USB polarity and it is the same as the Archos charger. The only thing that appears to be different is it has the extra 600ma more output than the Archos which of course should be good, but then different manufacturers control the charging in different ways and if Archos shut down the charging circuit on detection of any over current in order to prevent the battery from frying, rather than just regulating the charging current then this charger isn't suitable.
On the other hand it could be that the output switch over isn't working and I am only getting 1.01amp on the single output. Or maybe technical spec is wrong and it needs on of those linked power leads you sometimes get with small ext. HDDs.
So it will be going back and they will be asked to explain what's going on although it does charge my phone up quicker than on it's own 500ma charger and when it gets to 100% the phone just shuts down the charging as normal.
