Here at the Gadgeteer, we’re always on the lookout for something ‘different’ to review. So, when the folks at SideWinder contacted me to ask if I was interested in reviewing a manual powered cell phone charger, I said sure! Just the idea of cranking for talk minutes piqued my curiosity.

The SideWinder emergency cell phone charger is a small handheld unit measuring approximately 2 x 1 x 1 inch and weighing only 2.5 ounces. On one end there is a high-bright white LED and a connector for a cell phone cable. On the opposite end is an eyelet that an included woven hand strap can attach to.

On the right side of the device is a fold out plastic crank. To use the SideWinder, you unfold the crank, grip it in your right hand and start turning it as you would a fishing reel. As you turn, the LED begins to glow (if you don’t have the cell phone cable inserted). The faster you crank, the brighter it glows. 30 seconds of cranking will yield about 5 minutes of light. Turning the crank is not hard to do, but there is some resistance, and the gears inside the module do make a grinding noise. This isn’t a stealth device by any means. Output from the SideWinder is a steady 6.2 volts.

It makes a pretty nifty little flashlight that will never require replacement batteries as long as you don’t mind winding it up when the light gets dim. Of course the light is only one smallish LED, so don’t expect much from it. It works fine for reading in the dark or trying to find a key slot in a door. But, it doesn’t work too well for lighting your way in the dark.

The main function of the SideWinder is for charging your cell phone’s battery. A short (2ft) cable is included that plugs into a jack next to the LED on the module, while the other end plugs into the cell phone’s charger jack. I first tested the SideWinder with an old Motorola V120 that I had let the battery drain on for weeks and weeks. The phone would not turn on at all before I connected the SideWinder to it. The first thing I noticed when I started cranking was that the resistance seemed much stronger when connected to the cell phone than in did without it. According to the instructions, 2 minutes of charging would equate to around 6 minutes of talk time. After only about 1 minute of cranking, my left hand was tired from gripping the module and my right hand was cramping from winding the crank. I was surprised that after only a few seconds of cranking, that the phone turned on and showed the CHARGING indicator on the screen. However, if I let up on the cranking speed, the phone would turn off. Two minutes felt like forever, but when the time was up, I stopped winding, unplugged the SideWinder and tried to turn the phone on. No luck. It was still deader than a doornail. So I plugged the module back into the phone and cranked for another 2 minutes. Afterwards, I tried to turn the phone on and still nothing. At this point, I figured out, that this type of charger requires a lot of effort if you want to charge a dead battery.

My next test was with a Motorola T730. This time, I just let the battery drain to the point where the LOW BATTERY warning appeared on the screen. The results of this test were quite a bit better. Two minutes of cranking was sufficient enough to make that warning disappear for a few minutes of talking. Incidentally, you can charge with the SideWinder while your cell phone is powered on and you are talking. How you might be able to do this with only two hands is beyond me, but it is possible.

I can see where this device would be handy for outdoor enthusiasts. It is great for emergencies. People that are still within a cell phone service area (“Can you hear me now?”), but without access to an electrical outlet will find it to be a handy tool. The SideWinder feels like a robust little module that with a little effort, can juice up your cell phone for a quick call, anytime you need it.
