Go with the FireFlies E01 from the USA warehouse.
You can have it in 3 days for $35 shipped and it includes a 21700, charger, and 18650 adapter.
It is about 1.5” longer than the FW3, and on paper it may not be quite as bright.
HOWEVER.
It is a great design. It is bright and has an excellent throw for such a small light.
Biggest point: It can 5 on Turbo for 5 minutes without a discernable stepdown and it won’t burn your hand - heat handling is excellent.
Not really a pocket light, but there are small belt holsters on Amazon that work fine with it.
Turbo is rated at 2300 lumens, but you can keep it on for an extended period, unlike some of the other lights (D4V2, FW3, E07).
I bought two of them. Both came with a 21700 and a charger. Battery is not hi drain, because you can’t use that in this light. But it tests out at approx 5000 Mah
Did it list the charger and battery when you ordered or was it a pleasant surprise? Do you see them mentioned now? Maybe that deal is over or will be back when they are back in stock. Also, I only see 5700k in US warehouse but 5000k or 5700k in CN warehouse. $28 dollars in CN, 35 in US.
It did state that it included a battery.
Two weeks ago there was a total assortment available, all the same as CN.
Like I said, it comes in about three days. And for an extra $7 you get a battery and charger. Killer deal in my opinion.
