DoCoMo battery phone case recharges in 10 min
MAKUHARI, Japan–If you forget to charge your phone overnight, NTT DoCoMo has a prototype case that can do the job.
The prototype super-fast rechargeable battery case, being shown off here at Ceatec 2011 takes only 10 minutes for a full charge. When your phone battery dies, just slip it into the case for a recharge.
You still have to charge your phone at the regular speed, of course, but you have a portable source of power that’s fully juiced in minutes.
That could be handy if you’re not near a power source.
The case uses a lithium-titanate (LTO) battery that’s much faster on a recharge than lithium ion.
It’s similar to Toshiba’s Super Charge Ion Battery, which can recharge in 5 minutes and lasts for 6,000 charge-discharge cycles.
DoCoMo hasn’t said when the battery case could hit the market, or a possible price.
