Looks nice, I love the COB style lights for broad, yet close quarter even illumination.
I wonder about the charging and runtime specs though,
This makes it look like it doesn't have a protected charge circuit. Maybe that warning is just wrong because that setup would be dangerous for a Li-Ion battery. Usually in such cases w/o charge termination they don't provide USB charging capability, instead use a wall wart with a fixed peak 4.2V output. Maybe that text is just a mistake, throwback to the NiCd charging era where anything that wasn't rapid charged was just resistive current limited.
It's doubly confounding that it's spec'd as 5V 1A yet if it takes that to get a charge in 4 hours, what's the strategy supposed to be if charging at 500mA?
Meh I'm a stickler for accurate specs and another that doesn't make sense is a claimed 11 hrs 39 mins runtime, can't be a standardized 390 lumen rating off a 2200mAh cell. They must mean till it's barely lit or (hopefully) an over-discharge protection circuit cuts out the battery.
On the other hand, VALUE! I paid about $20 (at the time) for my Big Larry COB light and that didn't include batteries. It gets a similar 400lm from 2000mAh cells for about 4 hours so I'd expect apples:apples, that HF light runs around 4.5hr at equivalent good brightness.
Can the battery be swapped out quickly? That's one of the reasons I chose a Big Larry, that I didn't want to have to wait for cells to recharge, can just swap in already charged AA cells and keep working. If it can have the 18650 cell swapped then it meets that. Then again I use an AC powered LED shop light when I can, mostly the Big Larry for tight spots.
