If you’re a gadget-mad hiker then you need transportable power. This Solar ChumAlong keeps your solar cell angled towards the sun maximising its output. The solar cell puts out 5 Watts at 15V and charges your choice in 12 V battery (not supplied). You can then charge your stuff via the included alligator leads or cigarette lighter socket. Best of all the unit wakes up automatically at dawn and switches off at dusk so it’s completely autonomous. US$399.
ChumAlong is a device for orienting a solar photovoltaic panel toward the sun. As the sun’s position in the sky varies during the day, ChumAlong’s job is to make sure the Solar Panel is always pointing at the brightest point in the sky.
