The battery charger that makes you run… and run.. and run

There’s growing anger among the supporters of Ampy, a Kickstarter-funded wearable battery charger which promised to “power your devices from your motion” but has been described by disappointed investors as “a deadweight” and “an overpriced brick”.

It highlights the risk of investing in product ideas before they have actually launched.

Ampy says the complaints are being made by a small minority.

The battery pack is designed to be worn on the arm or elsewhere around the body.

The idea is that movement shakes internal magnets which generate current that is then stored in the battery. There are three LEDs which indicate how much energy is stored – three lights means it is fully charged.

While this is its main selling point, the Ampy can also be charged by being plugged into the wall.
