Energizer is saying goodbye to cumbersome battery chargers with what it claims is the world's smallest and lightest ultra-compact product.

The charger has been designed for people on the move and features a sliding bay which reduces its size by half when not in use. It can charge both AA and AAA batteries and has a dual voltage switch for the US. It also has a removable plug socket for easy transportation and automatic switch-off.

The product arrives in stores this week (rsp: £24.99).

A travel version, with an additional European plug fitting, will be added in August (rsp: £29.99).
