Keep in mind you can also run it off of an external battery pack. I use a 20,000 mah battery pack. Lasts for days. Get a 6 or 10 foot long programming cable and you could have the battery pack in a coat pocket or backpackI might just buy a third set of 3x AA Ni-MH so I have 2 sets ready to go for 1-2 days. Cheaper, easier and more reliable. No chance of destroying the radio that way. The $60 wireless charging mod might be worth it though.
I use these cables, cheap but great quality.
