Just before we went off to Interbike, our friend Jim at Bushnell sent us a sample from their new PowerSync line of portable solar chargers. The sample we received was the SolarWrap Mini:
Some details directly from Bushnell’s website:
-Durable, flexible solar panels roll up into a small lightweight package for easy storage
-High solar collectivity even in less than full sun conditions
-1x USB outputs for charging your devices
-1x Micro USB for charging from a wall outlet
-On board dual long-life Li Ion batteries
Also, according to Bushnell, the SolarWrap Mini will:
-charge the internal batteries via wall outlet in 4 hours
-charge the internal batteries in full sun in 10 hours
-provide 2.5 charges to camera or GPS, 2 charges to an MP3 player or 1 charge to a smartphone.
The solar panel itself is made of a very thin and flexible film over a woven nylon backing. It’s pretty amazing how far solar technology has come in the last 20 years — no heavy plastic or glass panels here!
Rolled up, the SolarWrap Mini is about the size of a BMX handlebar grip (about 4″ x 1.25″). It easily fits into a pocket or bag. The SolarWrap Mini comes with a “bikini-style” endcap system (rubber caps, elastic cords) to keep dust out of the USB ports. There’s a port on each end; one side houses the Micro USB “input” end (with LED charge/full indicator), the other has a standard fullsize USB port for output.
Unfurled, the device is just a hair over 18″ long. Hook-and-loop fasteners on one side of the solar panel keep everything tidy when it is rolled up. There’s a sewn eyelet on the end of the panel to lash the device to something. I would have liked to have seen additional lashing points so that I could securely strap this device to the top of my rear rack or over the top of my backpack as I rode.

As claimed, the SolarWrap Mini charged in about 4 hours via wall outlet, and about 6 hours via computer USB. In the most direct sunlight I could find, I left the charger out for 12 hours and the red charging lamp was still lit. I have no way to test how much charge was in the internal battery, but the red lamp indicates that there was additional charging room to spare. Granted, the sunlight shifted throughout that period and I may have gotten some inadvertent shade at times — this is why being able to securely lash the device out into full sun would be a great addition!
The SolarWrap Mini was a godsend during our trip to Interbike. With all the time spent in airports on my way to and from Las Vegas, I put the hurtin’ on my smartphone’s battery. By plugging in the SolarWrap Mini, I was able to fully recharge the battery. Eventually, I just used it as an auxiliary battery, leaving it plugged in to my phone while I texted, chatted, and Facebooked in the various terminals I visited. The SolarWrap Mini also came in handy out in the desert — allowing me to trickle-charge my phone via solar panel while I walked around the Outdoor Demo.
The Bushnell SolarWrap Mini retails for $89.99. I think that’s a reasonable price for this device — a little extra power when you really need it can be a lifesaver! Other than the issue of securely lashing the device, the SolarWrap Mini worked as claimed and kept me in contact during long trips away from electrical outlets.
Bushnell offers a few other sizes in their PowerSync line. That means there’s a charging solution for everyone’s needs!
