Last September, a company named Lumafield scanned 1,000 cylindrical lithium-ion batteries to shine a light on the hidden risks of cheaping out. At roughly the same time, I found myself testing two awesome new kinds of AA battery that recharge using USB-C cables.
It gave me an idea. Could we find the very best USB-C AA batteries by combining my own anecdotal testing with Lumafield’s scanning tech?
The answer seems to be yes! Knowing what I now know, the Zepath 3600mWh is the only rechargeable…
