Worst documentation ever This solar charger comes with a one page “manual” that tells you absolutely nothing about how to use the product. The charger has 4 blue LEDs in the bottom right corner, and at first they seemed to flash at random.On the plus side the charger, when exposed to direct sun light, (not indirect winter light) charges quickly and provides more than enough power to charge my Android phone every night.On the negative side, if you don’t figure out how to use the charger (and you won’t from their instructions) you can’t charge your device. Here’s the owners manual they should have included:1) When placed in direct sun light, the four LEDs at the bottom right of the device will flash from left to right. The rate at which they are flashing indicates the rate at which the internal battery is being charged. The faster they flash, the more power you are getting from the sun. Put the solar cells in direct sun light for maximum charge.2) When the device…
Very Useful, Well-made Accessory I ordered both the Opteka BP-SC4000 and the XTG Technology Solar Charger, just to compare the two. I was looking for a compact, lightweight, solar-rechargeable backup power supply for my iPod Touch, satelite GPS unit, and cell phone. Bottom line: Except for the User Guide, which is practically worthless, I found the Opteka unit to be superior in almost every way to the XTG model; here’s why:1. The specs for the Lithium-polymer battery on the Opteka BP-SC4000 claim 4000mAh capacity -almost three times the capacity of the battery on the XTG.2. The maximum solar charge rate for the Opteka is spec’d at 250mA – more than twice the 120mA rate specified for the XTG. This should translate into significantly faster recharging of the Opteka’s onboard battery for the same amount of draw-down. (Example: If your cell phone, during recharging, draws 1000ma, it will take about 4 hours of direct sun to replace the charge in the Opteka vs approx 8.5 hours for the XTG.)…
