Lumintop B01 has fours settings: low, medium, high, and turbo for 15, 250, 450, and 900 lumens. It draws 0.4A on medium and 1 Amp on high. Turbo is useless. With a 5000 ma 21700 battery, mine will run 10-11 hours on medium and just under 5 hours on high. I ran it on high for 3 hours Saturday before sleeping and then an hour just before sunrise and then had it on low. So, one battery is enough for me on a 600k but I bring one spare.
A 10,000mah power bank is 38 Watts (10,000 mah times 3.8 volts) and should power the 5 volt B01 for around 7 hours on high. I would test how many amps your Anker actually holds.
(The light is ok. I like the 4K emitter over the really hot 6K that are more typically found on bike lights)
