..and I killed it. I'm not sure if the mini USB charger port contacts spread, if the charger board is bad, or if the battery is completely shot. But, I beat the crap outta this thing! What i really needed was a new phone due to dead battery. This charger was plugged into the phone from noon to midnight for the last 3months.

I got it down to 1 LED on the power meter. If I plug it in and lay the cord just right, the LED flashes to tell me it's charging. I've left it alone for hours on end on the charger. Every time I came back to it, it quit charging on it's own. I was able to pull one LED, may be two after a long (failed) charge. I still got 2-3 evenings of continual charge to the phone off of only 1-2 LEDs.

Last night, it finally stopped charging the phone. I left it on the truck dash all day long, out in the sun. When I retrieved it, nuttin....completely dead. No flash light even.

I think I'm gonna kit bash it. Imma pull the battery out, gut the inboard charger and replace with guts from a 99cent gas station phone charger, and place it all in a smaller project box.

If you're still looking for a BOB charger, I still recommend the unit. If you're like me and putting off replacing a phone due to age and dead battery, this will buy you some time,...but it ain't a fix.

When you are dead, you don't know you are dead. It is difficult only for the others. It is the same when you are stupid.

I don't know if this will help, but I saw on YouTube I think, about a rechargeable battery going dead.  He recommend that you freeze the battery for a couple days.  Then let it thaw, then charge.  I recently did this to 2 lap top batteries.  It worked on both. 

I don't know why it worked or the physics involved, but it work on both laptops. I had already ordered new batteries, and would have to wait several day for them to come in.  So what did I have to loose?  What do you have to loose?

The battery still takes a charge from an external bench charger. I can't tell you the extent of life left. I'm sure memory has taken it's toll on the pack.

The charging board has failed in some way, which was the ultimate end of the device.
