Batboostor claims to be an eco-friendly recharger of disposable batteries, both alkaline and saline. Instead of throwing batteries away, you can re-charge them up to 20 times before taking them to the recycling bin. The device, which is priced at 45 euros, accommodates AAA, AA and 6LR61 batteries.
The gadget – unlike traditional rechargers which damage the batteries with heat – relies on a cold charger which does not generate any heat, supplying a discontinued charge in packets. Comes with a one-year guarantee. Available from La Boutique Econologique.
