The Changers solar panel, power pack/data logger and community is an interesting concept and, I think, a well designed product. Lithium battery charging and solar power don’t fit together easily but when they do you have the potential to get a powerful and lightweight solution. The equipment arrived today, it’s in working order and over the following weeks i’ll be doing some testing.
The consumer-focused solar charging sector has been damaged in recent years by the influx of cheap China-manufacture red solar chargers that really don’t do what they say. This solution from Changers.com is in a different league. I had the pleasure of speaking to the founders today and got a bit of tech talk in. What I found out got me excited about doing another solar computing tour because the intelligent power pack is one of the best i’ve seen. I want to pair it with the Lenovo Lynx PC. Clovertrail is perfect for travel computing and the Lynx even charges via micro USB. In theory, one 4hr charging session will charge about 60% of the Lenovo’s internal battery for about 4hrs of work. 1hr charging for 1hr computing is a real groundbreaking achievement, if it works.
The Powerocks Stone 3 portable power pack for iPad and Galaxy Tab solves a problem. It’s all very well having a common interface for charging but when people break the specs it becomes less useful. The iPad and Galaxy Tab charge using very high currents through a USB port that excedes the capability of the USB port you’ll find on nearly all laptops and PCs which means you generally have to carry the mains charger around with you. I found a portable power pack at IFA that supplies the correct current to allow full-speed charing on the go and it works. At least with the Galaxy Tab I tested with it.
There’s no European distributor for the Stone 3 yet so you’ll have to keep your eyes open for availability. Alternatively, wait a while because I’ve got a unit coming from Znex. The Power-Pack IP is said to do the same so i’m looking forward to testing one that’s available right now.
Here’s a video and you’ll find some images below that.
