guys.. i can't remember the name. but i came across a particular solarpowered device in the last hwm issue.

3 fin, fan lookalike device that has it's own battery.
full charge under teh sun is 3hours.
can charge ur hp after that.

Even when there's no sun, it has it' own battery juice to charge ur hp should u need it.
i think it's quite cool.

if i dun remember wrong, is ard USD99

Don't think so. Camera batteries are now made of lithium Ion and need special chargers or risk explosion or at least damage to your other po puay equipment in the bag :nono:

handphone batteries oso lithium ion wad rite?
can charge hp y cannot charge camera? just findnig the right adapter maybE?

thats because the handphone already has a built in charger/regulator, so all you need is in input the correct voltage.
