Review: Skilhunt H150 - my favorite small headlamp
The Skilhunt H150 is a small headlamp with great color quality, magnetic charging, and the ability to use both 14500 Li-ion and AA batteries. It sets a new standard in its size class.
Oh how interesting, that is a shame that they’ve removed that feature. I definitely would appreciate that compatibility, as I enjoy being able to use any AA battery ( or any other common type) for my flashlight, but would also love being able to use other battery types. Thanks for the info!
Reddit user fnksb pointed out that the measured current, runtime, and expected battery capacity didn't quite add up for the 14500s. I tested both my Vapcell H10s on my analyzing charger and got 737 mAh and 797 mAh, which is considerably lower than the 924 mAh figure I had been using. I've recalculated efficiency numbers based on a battery capacity of 797 mAh and also reran the M1 mode runtime test.
I got a bit longer runtime this time around and of course a little higher efficiency in every mode. My overall analysis remains the same though: boost/linear is a little disappointing and I'd much rather see boost/buck or boost-only using a 6V LED like the Nichia B35AM. So far, I think only the Emisar D3AA takes the boost-only approach to the AA/14500 problem.
