Laptops are renown for having poor battery working times, and that’s where the YoGen MAX comes in useful. By exploiting foot power, you can charge devices that need a 50-60W power supply, such as laptops.
The YoGen MAX exploits foot motion to charge up the internal 12V 1,500 – 3,000 mAh lithium-ion battery. You could use the YoGen MAX as part of your exercise regime, or even in front of the TV. You then get free laptop charging power.
When used for travel, the YoGen MAX measures 170 x 170 x 45mm, and when in use, it measures 170 x170 x 93mm. If you’re travelling, it could be a viable eco-friendly battery charger alternative, compared to using a solar battery charger. It’s refreshing to find a range of laptop accessories that actually have some use!
