Huawei, China's largest mobile phone manufacturer, is releasing a phone that can be thought of as the inflight refuelling system of the mobile world: it can be used to recharge other phones.

It's the successor to a phone of the same size launched last year.
The first Ascend Mate was not sold in the US, but Huawei CEO Richard Yu said the Mate2 would be.
