GP Solar Charger
To help minimize the waste problems as far as using batteries are concerned, rechargeable batteries are being offered in the market as a great alternative. Now while that may have resolved one issue, the manner of recharging may be another issue. Energy is a growing concern and the manner of recharging or plugging them into outlets is sure to be a problem.
But for the GPS solar charger, this issue should be resolved as well.
According to GP, it takes almost six hours to recharge two AA batteries (or 2 hours for AAA cells) under direct sunlight, which is slightly longer than what is usually expected of regular AC battery chargers. The advantage, however, is that the Solar Charger can be used outdoors where there is no access to the mains. Of course, with solar power being a free renewable source of energy, the Solar Charger also makes more economic and eco-friendly sense, too.
