>The prototype charger is currently the size of a laptop charger That's not the charger, that's the battery attached to the phone. A Li-Ion would blow to pieces charging at 120C (120 times the capacity). So what's wrong: - that's the battery - they don't actually say the battery capacity (the phone would report 100% charge even with a 100mAh battery, if it's "fully charged"). - they don't say anything else about the battery (weight, internal resistance) - the current provided by that plug they connect to the battery can probably be used to weld thin metal, if the battery capacity is close to the original one (think sparks/small fires in an accidental short circuit)
