solar trickle charger other uses!

skater_kat

i have a trickle charger which is unused. (12v 2.4w i think)

i am wondering if it would work if i put it up in my southfacing window and tried to run a small battery off it, like a small scooter/motorbike battery type affair, which could in turn do things like power my mobile, ipod etc.

any techie able to help figure this out?

thanks

Its 2.4w. It can barely light a bulb. A normal 12V 4ah scooter battery would take roughly 4 full days to charge. But as there is only daylight around 12hrs a day at the moment, it would take over a week.

maybe a very small model scooter or motorbike battery but that's about it!

Like Hammyman says, 2.4watts can bearly light a tiny lightbulb or a couple of LED's but that's about it unless you can leave something on charge for a few weeks at a time.

Idea:
get a battery charger and a load of rechargeable batteries. hook it up to the charger and leave for a week or so changing them when they are full charged.. lol

Or use it to trickle charge a spare mobile battery.

Go to Poundland and buy a USB car adapter* plus the two-cell USB battery charger. Attach the negative output from the solar panel to the external spring clips of the car adapter, and the positive to its nozzle. Insert the battery charger into the USB socket and this will charge quite efficiently any pair of AA or AAA NiCad or NmHi rechargeable batteries that you have.
