Verdict
If you are looking for a power solution for emergencies or for days camping, away from electricity that can run your mobile phone or MP3 player, the Medis Fuel Cell is great. If you want something that you can toss in the cellar in case of an emergency the expiration date can be a hassle, still this is an interesting product that has much less environmental impact than disposable batteries.
