DIY LED light jvc gr-dv500u charger bulb transform old man lamp, spend minimal, the effect is very good, and continue to carry on the DIY spirit, spread, use small snail mouth bulb drawn power, transfer to standard miniUSB interface can give ordinary mobile phone batteries.

Now most of the cell phone charger jvc gr-d270u charger is actually a 5V dc output power, so long as can provide stable current power 5V can be to recharge the phone number five, and section 4 nimh battery good electricity is exactly the cell phone battery, to more than 5V should be just right. Checked on the net, does anyone really do this, he is oneself do four batteries power box, and my hand head lamp is four batteries, not just right? So immediately begin, still need a little light bulb snail mouth, then grafted in a root do miniUSB line will do.

The snail mouth posted above references miniUSB line can directly find a miniUSB this data, as long as the can, I use a broken charger jvc gr-d270 charger. Cut open, it after it 2 lines, red is positive, blue is negative, if is, must make clear data which two line is power supply, made a mistake is to be burned cell phones, meanwhile polarity is also must make right, wrong also is very dangerous, don't know is there to prevent phone circuit protection of reverse connect, be careful.

So, after two days of activities, generally a night of electricity is exhaustless head lamp, just the cell phone battery night. I use mobile phones do GPS navigation, had the recharge, the next trip, don't worry, ha ha.

Checked, like someone say this to cell phone charging, blunt discontent, even then, I feel, had this wire, emergency, direct to cell phone power supply is no problem, after all four sections BiRongLiang almost nimh batteries are cell phone batteries 2 times, can be at ease use mobile GPS. jvc gr-dv800u charger
