Hi Assaf: All of the Baofeng radios I'm aware of use a drop-in charger so while it may be possible to charge and operate them at the same time, it probably isn't practical. You can learn everything you want to know about Baofeng radios at: http://www.miklor.com Search for the model of interest, sit back and read. There's far more info there than you'll find in the owner's manuals. 73s, Steve VE3KC
