If you own a mobile phone or an iPod -- or more likely, both -- chances are you've been in a situation where a solar charger would've been welcome. So far, though, the price of solar power may have been putting you off. The Solio typically costs £60 and solar backpacks from the likes of Reware or Voltaic Systems typically cost £100+, while the Freeloader costs just £23 if you shop around online.
The concept's simple. The folded-up charger opens into two teeny solar panels that you attach to a battery in the middle. Stick it on a window sill in the sun or, even better, outside, and it'll start converting the sun's light into electricity.
The Freeloader's makers claim the battery can top up to full in five hours, but we found in winter sun behind a window it took more like eight to nine hours to power up around half-full. Still, that was enough to bump a 5.5G iPod battery from half- to fully-charged in the evening. Generally, we were impressed with how much electricity the Freeloader generated, even in gloomy conditions.

Obviously, powering via the sun is the greenest option, but the other road you can take is to power up using a computer. Just plug in the supplied USB cable and you can top the battery to full in three hours, creating a handy source of power for most nearby gadgets.
This solar lovely comes with a decent bunch of adapters for most phone names (Nokia, Samsung, Moto), plus games consoles like the PSP and DS, as well as anything that charges via USB, like an iPod. See here for a full list of adapters.
Although sod's law says you won't have the Freeloader on you when you most need it, the charger is fairly portable. It's about the size of an old-fashioned chunky phone like the Sony Ericsson P990i, but is surprisingly light and pocket-friendly at just 185g. Continue reading...
