How many times have been out on the road and your mobile phone battery has died on you?

It is a lonely experience to know that you are completely on your own.

A new product, Instant Power, is making all that a thing of the past as it allows a flat battery to be recharged without an electrical outlet.

It is absolutely ideal for emergencies on the side of the road, up a mountain or even on a sailing boat.

The Instant Power pack is about the size of a slim bar of soap and comes complete with an adapter to fit your phone (the adapters are all phone specific so you do have to know what phone you want to use it with).

The adapter will last the life of your phone, but the power packs are good for around three charges and, after that, are completely disposable.

The unit is extremely lightweight and can be carried in a pocket or briefcase without any danger of leaking chemicals or other noxious nasties.

Simply plug the Instant Power pack adapter into your phone and connect the other end to the power pack.

Your phone battery will immediately start to charge and can even be used while it is gathering power.

The makers claim the Instant Power charger is environmentally-friendly, safe to use and safe to dispose of after use. It is an equally useful accessory to ensure your personal digital assistant stays fully charged.

Genuine plug 'n' play at its best.
