I wouldn’t want my radio to depend only on AA batteries. Usually those are as an emergency. They would maybe able to generate 1-2 call with them and even i don’t think you would get the full 5-6 W out of your radio. Instead my radio is usb rechargeable. There a lot of people now carrying electronic and battery banks in group making easy to recharge in case of emergency. I have actually an emergency bank in my ditch bag. That way i can recharge my phone and my radio.
