Reply With QuoteI'm not an expert but first off is the existing transformer heavy (i.e. has a wire wound transformer inside) or quite light like most modern phone chargers (i.e. electronic / switch mode transformer). The two act quite differently under load.

A question for those with any electronics or electrical savvy (I have none). I hope there is enough information below.

I have a recently purchased Baofeng VHF/UHF FM Dual Band CB with a 240V Lithium ion Battery transformer charger with output of DC 8.4V and 600 mA.
Q1 - Can I use any of my accumulation of DC car chargers collected over the years to plug into the charger/docking station? (the 240V transformer bit has an RCA type plug into the back of the charging/docking station so can be replaced). I don't have an 8.4V output 12V charger but have two adjustable (7.5V or 9V) (one at 1.2A and one at 800mA) plus a 7.4V with 600mA as well as any number of direct 12V to 12V versions.
I'm assuming a 12V to 12V direct charger is NOT acceptable and will blow something.

Similarly, my iCom IC-41S CB has a 240V transformer that outputs 16V and 0.92A (plus 14.88W and Efficiency Level IV whatever they mean). It also has an RCA connector system. I thought I had purchased a specific 12V charger connector as part of the package, but it seems to have disappeared.
Q2 - Can I use/plug in a standard 12V car charger into the charging/docking station for this unit, or will a direct 12V/12V not generate enough power for full recharging?
Of course everything is negative ground.

regards q1 you can use the adjustable 12 charger set at 9v for the boafeng providing it has the same polarity and connector as the factory one, is this the radio

and q2 same applies this is the brochure for the icom
http://www.icom-australia.com/produc...20Brochure.pdf
the brochure dosnt say what the output for the transformer is so have a look at the sticker on it and adjust your 12v charger to the nearest setting above the voltage stated.
In both cases plug into the charging dock

Rufusking - yes both are the lightweight version transformers.Originally Posted by THE BOOGER

Thanks Booger - brilliant response.
Yes the link is correct/I have the UV-5R (which I will find out how to program one day as the cryptic instructions are not detailed enough for me and I'll hopefully get onto some web videos as previously suggested on this wonderful site/people).
Interestingly, although the iCom Li-ion battery is listed as 7.4V [the same as the Baofeng] , the output for the iCom transformer is 16V - and they wonder why dummies like me get confused!!!

Just a cautious note, these devices are illegal for use even if you only use it for UHF CB operation.
ACMA radio inspectors across the country are on the hunt for these sorts of devices.

Just a simple but most likely a stupid question ????????????
Why are the handheld vhf/uhf transceivers illegal in Australia if there programed to operate on UHF only
BTW im only new to this communications stuff
