Baofeng UV-82 Charge Battery with AC Invertor?

[rtorella]

Recently purchased a Baofeng UV-82HP. There are no DC cigarette plugs which will work with the desktop charger and the battery packs lack any power plug openings.

Here is my question. I have a 12v DC to 110v AC Power Invertor, plugs in the cigarette lighter. I used to run my laptop computer off it when on the road.

The wall adapter is 100-240v input with output of 10v 0.5a to the desktop charger. If the AC Power Invertor runs and charges my laptop computer, would it also work if I plugged in the Baofeng wall adapter into it and charge the batteries with the desktop charger?

Would that work when on the road, since there is no other way to charge the batteries except with the wall desktop charger??

Thx,

It will. The charger with this radio sucks. I also just picked up 2 BF888's that use a similar charger. We are at the NASCAR track and the only way i can charge is via inverter.

The 'desktop charger' has a DC voltage requirement of approximately 10 volts, check the specs on your charger. Too high of a voltage into the charger will destroy the charging circuit, a very small IC that does not seem to have any data on it.

I have not found any good cig lighter cords with a built in regulator to match the requirement.

I did make up a few cig plug cords with a regulator in them using a three terminal regulator IC on a small heatsink.

A search for "Baofeng e-bay" turned up several.

Yes, it's just like you were

plugging into your house wall outlet.

Inverter is not a good way to do this. It is much better to put together a very simple DC regulator circuit to drop the 12-14V from the vehicle to 10V to go into the charge base.
I have one fitted in an adaptor cable.

(although worth noting that the switchmode psus 'may' not work with non-sine wave inverters)

I am not electronically inclined, so it is the invertor or nothing. I plugged the invertor in, then the wall adapter. Plugged in the power cord to the cradle and watched the green power light come on while I held my breath. Did not smell smoke and the cradle did not get hot. Contacted BaofengTech support, who said the low power 50watt/100watt peak invertor should work with no problems. I have some of the Ebay DC cords but do not know how to tell the power plug size and polarity. Tried the local radio shack who wanted to sell me the $45 kit with the 10 adapters.

Save your money. The inverter will work finel

As already posted, it's just like you were plugging in to your house receptacle.

KCRAF...I'm with you on that one. Thanks

You asked the questions and got valid answers, yet you continue to talk about an inverter.
1. The 12 volt inverteer output will likely damage the UV-82 charging cradle.
2. Any Baofeng cable with a cigarette lighter plug will work with the UV-82 charging cradle.

Hey chill out there! Your opinion is not the only valid one here. Split down the middle so your "yet you continue to talk" blah blah is irrelevant. Please find another topic to be negate on, or go to Facebook where that thrives.

I was merely gathering several opinions regarding, yes, using an Invertor. I have searched for a DC Cigarette plug to use on the desktop charger. The ones on Ebay do not show or have the correct power end. Otherwise, that would be my first choice.

Didn't you read my last post?

Yes 12 volts into the charger will destroy the battery charging chip.

Most all "Baofeng cable with a cigarette lighter plug" do NOT have a voltage regulator in them.
