Hi,
I noticed a few people talking about making a 'DIY' USB powerbank with these Eneloops.
Just got a great deal from Dick Smith and interested in taking them with me overseas; has anyone got any ideas as the best way to use these batteries to charge my phone (HTC one) and PSP?
Cheers!

Thanks Scrimshaw! Can that one charge the batteries as well?
Yes, it's also a charger.
Not really ideal.. AA's aren't particularly energy dense. You'd be better off buying a Lithium battery that is more space efficient and has significantly higher energy density to boot especially for travel where space and weight are important factors.
ie. a Lithium battery pack of the same dimensions as a AA battery pack will store 3-4 times more power!
Thanks for the advice, guess I OzBargained myself getting the Eneloops. Never mind. Thanks again!
yes me… use this and 4 eneloop:

Thanks! I'll give it a try. Will have enough space to bring batteries and a Lithium battery as well. Got a few longggg bus rides :)
I quite like the look of this one…

are these any good?
Way too expensive.
For $30 dollars, you might as well go buy yourself a decent powerbank.
for people with enloop charger, do you think it takes long time to wait the charger green/yellow light to go off? i think around 8-10 hours? or you just recharge for 6 hours and then turn off even if the lights still on?
The better DIY PowerBank would be an enclosure from Fasttech, combined with trusted Protected 18650 cells. These are Lithium Ions, 3.7V, up to 3400mAh. Larger than AAs but much greater energy density.
(Believe it or not, 18650 Lithium Ion batteries are what are used in the Tesla electric cars - 6,000-odd of the things!)
