Brunton Hydrogen Reactor
The product itself is great, does what it says on the tin in my opinion.
there are some drawbacks however that some people may not realise.
its difficult to find places to get the "cores" recharged as not many places have bought the recharge stations... they may be waiting to see if the technology takes off before paying for one?(had to buy my own)
and then the second drawback is that it pumps out 1amp of power, so its good enough to charge most electronics but for those who have a smart phone and thats its intended user then may struggle with this.
i have a GS4 and it does charge up but it is very slow (from 29% to 60ish % took 6hours i think before i got bored? and that was with energy saving mode with wifi/bluetooth + data turned off)
overall though its a good device that does what it says (it charges my GPS and headtorch ect just not power hungry 2amp kit)
but it might be worth waiting for the masses to catch on and you can find a local refill station.(gooutdoors just says soon on the website and maplin only can do it in some stores)
