For anyone with a Kaito KA500 or KA600 radio, check out this simple mod you can do: https://www.youtube.com/watch?v=wwih6htDxoo By default, the Kaito radios have two separate battery compartments: one for an included battery pack, and another for your AA batteries. The solar panel, hand crank, and power bank functions only work with the former, not the latter. This mod lets you ditch the (probably poor quality) generic Chinese rechargeable battery pack, and run the radio fully off your high quality Eneloops. The solar panel and crank charger will recharge your Eneloops, and you’ll be able to use your Eneloops as a power bank. Do keep in mind though that you must never use non-rechargeable batteries while using this mod. I wish this could also be done with the smaller Kaito Voyager V2, but it doesn’t seem possible, at least without opening it up and messing with the internal electronics.
Great article. Don’t worry about the naysayers on Reddit. You’re 100% correct. I’m personally sick to death of having to babysit all my Lithium-ion batteries in all my modern “smart” devices. It’s so frustrating how quickly they lose their charge and how easily they get ruined if left alone. AA master race.
