Recharge the Voltmaker at home or at work.
At work or at home, there's nothing easier than plugging your Voltmaker into your computer via USB to recharge its battery effortlessly. Just recharge your Voltmaker as you'd recharge your smartphone using your computer, in under 2 hours.
You can also plug your Voltmaker into the mains to recharge it. It is fully charged after two hours.
Two different USB ports to avoid mistakes.
The Voltmaker is equipped with two USB ports, allowing you to recharge your portable devices (smartphones, MP3 players, etc.) and the Voltmaker's own battery. In order to avoid mistakes, the Voltmaker is supplied with a standard 5V Type A USB port, for recharging your portable devices and a micro USB port, used to recharge the Voltmaker.
The Voltmaker is also equipped with a charging indicator LED allowing you to check if the battery is charged.
A high density battery.
The Voltmaker uses high density lithium batteries (2,000 mAh), which can be recharged in under 2 hours when plugged into the mains. These batteries are protected against deep discharge and overcharge. This protection improves battery life (they can be used for over 100,000 hours!). They also tolerate partial charging without any problems, making them fully compatible with manual charging.
When fully charged, these batteries can completely recharge an iPhone's battery.
A fun charging process you can use anytime.
With a few flicks of the wrist, you can generate your own energy to recharge your portable devices. The thrust of the hand is enough to activate the generator. This fun, effortless and single-handed movement, inspired by the ratchet device, allows you to have enough battery to make a phone-call, listen to your favorite song, or to provide lighting when you're in the cellar, in a few minutes.
