It must be working because the little red light on the thingy came on, the GPS had the picture on it till it went completely flat and the phone said "charging 13%" followed by "charging 11%" when I stopped and "charging 3%" when I got home. They're discharging much quicker then they would have done if I hadn't plugged them in.
I've plugged them in at home (phone on the PC and GPS on mains) and they are charging fine now so it must be the 12v socket in the van.
........................Also, as a back-up for when my phone battery is dying (dead useful if cycling) ...
EC Technology 2nd Gen Deluxe 22400mAh 3 USB Output: Amazon.co.uk: Electronics
I originally bought one for my daughter and was so impressed I got myself one ... I use it mostly for keeping my phone alive when geocaching on my bike if I'm using the phone's GPS and caching app.
Might be worth considering if you have high USB needs.
I had a .5 amp wouldn't charge my phone bought a 2,4 charged OK.Surely 0.5 amp is enough for charging phones etc?
Help please from any knowledgeable bods out there.
The 12v socket in my van has suddenly taken to discharging things plugged into it instead of charging them up. It did it to my GPS on Friday night and has gone and done it to my phone today. Why?
