something that didn't exist in 2016 and does now, are AA batteries that are composed of an internal lithium ion cell, a DC-DC converter for 1.5VDC output to the end terminals, and internal 5V-USB to li-ion charge controller circuitry.
With a USB port literally built into the body of the battery. They're more expensive, but can pay for themselves...

there are lots of other models if you search for "AA battery lithium ion USB"
I would recommend these over anything that is NiMH based (memory effect) or needs a proprietary charger.
- intrasight 5y agoI'd seen those in the past. Prices have come down. Am curious what are the benefits over NiMN.
- walrus01 5y agoshould be little to no memory effect unlike NiMH
- Zak 5y agoModern, high-quality NiMH has little to no memory effect. Eneloops are the gold standard, though rumor has it many other brands have caught up.
- exhilaration 5y agoAt first glance, capacity seems to be the main benefit, from the above link: Battery Capacity: 3400mWh Compare that to Eneloop pros: 2500mAh Using this converter https://convert-formula.com/mwh-mahz https://convert-formula.com/mwh-mahz 3400mWh at 1.5v is 2256mAh so the Eneloop pros actually have more capacity.
- walrus01 5y agoDownside being that the eneloop pro needs its own charger, these should be able to charge from any phone charger, or come with their own 4-to-1 usb cable.
