Hello

I am off to a festival for 3 days in Aug, does anyone recommend any Solar chargers that would be good to take?

I can't really recommend solar chargers at all. They are not great in the UK. I have used a Solio one at festivals, but in all honesty charging it via the sun is most likely to take days. You generally have to keep them aimed at the sun, and you will have better things to do! Most of them do have built in batteries that you can charge directly though.

Better bet is a charger with either a large built in battery, or one that uses chargeable AAs.

The usual power saving tips apply - turn off WiFi, 3G, GPS, etc and even the whole phone when you are not using it.

I would also consider a cheapo handset that sips battery power. I have a couple kicking around that will last nigh on a week without charging. The upside is f you drop it in the mud or get it nicked you won't care.

Don't bother, they are a waste of time.
Get a Powermonkey or similar

ive recently got hold of a new trent IMP1000 charger pack, and that is nothing more than a large capaicaty battery pack, that cna be used to re-charge mobile phones etc, with it i can get up to 4 days extra use from my android phone.

Thanks for your replies. These AA battery chargers, realistically how much charge would i get from charging via batteries?

I'm thinking of the battery pack, what one is good for the SGS?

I got one of these off ebay for my Galaxy S:

Its a replacement battery which in my Galaxy S lasts twice as long as the normal battery. It is thicker than the standard battery though so it comes with a replacement back cover. It makes the phone more bulky of course but i'm more than happy for the peace of mind of not worrying about the battery running out! Take the standard battery (and the standard back cover) with you fully charged as well and you've got a spare battery of course. Buy 2 of these new batteries, charge them up before you go and with the standard battery as well you should have more than enough power for 3 days! You also won't have to wait for the phone to be charged whilst youre away - just change the battery when it goes flat.

I would agree about solar chargers. Total waste of time.

Unless you have a power requirement that makes it problematic changing the battery, 2 or 3 normal spare batteries are the lightest and cheapest option.

Probably under £3 a piece off ebay or elsewhere. Cycle each battery 4 or 5 times to ensure they work at full capacity.
Solar chargers are bulky, expensive and often useless in the UK.

Whats these external chargers like?
