About 9000mAh per core he said towards the end of the video. He also said a core was equivalent to 30 AA batteries, if you bought 30 batteries from the pound shop maybe!! A good alkali AA battery is 2500mAh and a good Lithium AA battery is 3000+mAh.
He said it would charge a typical smart phone 6 times and a tablet to about 80% as their batteries are about 11000mAh.
I suspect 3 Lithium AAA batteries in a backup phone charger holder thingy has the same capacity. Cheaper and lighter. Good quality NiMH rechargeables would be even better and much cheaper! I suspect the price of the device, cores and recharges of the cores is going to be painful.
Fun tech gadget but still seems to be trailing batteries. Gimmick. Give us a charger fuel cell that will run from just a piped H2 source.
Correction Update
The rechargeable hydroCores each output 4500mah [as two are supplied with the unit the max is 9000mah]
Each hydroCore can provide approx power to charge a tablet to 70 or 80% or an iPhone three (3) times as two hydroCores are supplied that would be to charge an iPhone six times.
The product costs in the USA $170 and extra hydroCores are $20 - assuming they are simply swapped over for fully charged hydroCores.
The cost in the UK is £135 for the Hydrogen Reactor.
Each hydroCore units can be recharged up to 1000 times and is then discarded [recycled as tin].
The Hydrogen Reactor is USA TSA [Transportation Security Administration] approved so can be transported in your carry on luggage.
The hydroCores can be recharged multiple times using the Brunton Hydrolizer - a H2O based hydrogen core recharger can be purchased to do this so the hydroCorers are fully recyclable.
In the USA the recharger Bruntons Hydrolizer costs $280.
All of the Brunton equipment has a full life long product replacement guarantee if the product is somehow damaged. Rosker UK [rosker dot com] is the UK distributer of Brunton products.
