Another mobile charger review, these are getting to be fun! This time it’s a solar-powered charger that can be attached to pretty much anything with it’s velcro, fold-over strap. Unfortunately, because it is solar-powered, it takes a while to charge; according to the instructions that came with the SolarStrap (which you can download and read on their site), if it’s a sunny day it will take 12 hours to charge, if it’s partly cloudy you are looking at a full 24-hour charge time, or if it is completely cloudy it’s going to take 5 days of charging.
To speed up the process, though, (or if you just so happen to get it when the heavens decide to rain every day of the week) they include a handy AC charger and a USB charge cable. I let mine hang on the blinds in my office at home for a day and then plugged it up that night to top off the charge.
To show the charge status of the SolarStrap you are given two LEDs, one green and one red. The green one, when a device is plugged in, will flash according to the SolarStrap’s battery charge. Four green blinks is full, three green blinks is nearly full, and so on until you have no green blinks and only the red one blinks once, which means the battery is empty. When charging the battery with an AC adapter the red LED will continuously blink and it will cease blinking when the charge is complete.
I received a few adaptors with my review unit as well, along with a generic “charging” cable I received: USB-B, USB mini, USB mini 8-pin, USB-A female, Samsung D600/A300, Samsung G600, Nokia 2.1mm, Sony Ericsson, and iPhone/iPod adaptors. There are other target specific adaptors available as well as a cigarette lighter and AC adaptor. According to the instructions you only get the strap, the charging cable, and the user guide, so you will be able to buy adaptors to suit your needs when you get it.
The SolarStrap has kept a charge very well and is pretty flexible. It’s made of some kind of a foam exterior with the wiring, battery, and solar panel glued into place between the two pieces of foam. I was assured that this was not a production unit and it had been hand-glued, which is good because in one or two places around the solar panel the foam wasn’t glued down all the way.
As for the foam itself, I don’t know how well it will hold up, after unvelcroing and velcroing a few times I could see how it could start to break up if it was used regularly. Also, if it was left out in the sun (on your car’s dashboard or in a window sill) I’m not sure how the foam would hold up.
The only beef I have with the SolarStrap is that I don’t know what the charge amount on the battery is until I connect a device to it. I wish there were a button on the battery to show charge status of the battery, or something along those lines. But, overall, it’s a great charger if you are out and about a lot but if you are like me and stuck in a windowless office all day it may not be ideal for you.
The charger is scheduled for shipping this month (August ‘09) and currently there are only a few dealers listed on their site, with only one being in the USA. The SolarStrap is priced at 29.00€ (about USD$41), for more information visit the Suntrica website.
