Re: Battery capable of charging in 30 seconds

Ah, thanks. Yeah I was pretty sure phone modifications would be necessary but just how much was the curious part. Even half the capacity of the original phone battery (1.3 amp-hours) would require a current of over 150 amps to charge in that time, even assuming 100% efficiency.

Well if you can charge it to full in less than a minute, then you can practically recharge it several times a day... Helps as bit IMO.

It's not that bad. These cables take 50,000 amps and aren't much thicker than a petrol hose.
