Ok it seems like you can select 0.5, 1 A or 2 A, its about £8 more than the nitecore in the UK. I like the fact the nitecore does Imr, Inr,and all other types of li-ion, NI-cd, Ni-MH, and LiFePO4.
This is important as I own A few torches/flashlights, the brightest run on a single 18650, it would blind a demon, I tried it on my self on mid and was blind for about 5 minutes. If someone tried anything at night with you, you would only have to put that on high for under a second in their eyes,and their night vision would be buggered, and they would have no idea where you are.
I can see how they was used as the first mechs, it is the same size as my mech, like exactly the same.
That is about 600 lumens (they claim 900, but its actually 600, about 350 on mid which is still extremely bright).
I also need a charger that does standard AAA rechargeables. I have a very bright keyring torch/flashlight, 80 lumen, (It claims 100 but has been tested to be 80, its still a cree XP-E in it, kind of the little brother to the XM-L2 in my bigger 18650 torch,, in it, so is bloody bright) the old maglites with the big batteries were 8 lumens. So, from a tiny AAA cell, you get 10 times the power of light of an old maglite, not 10 times the brightness though, similar to watts in speakers, double the watts does not equal double the power, 10 times does.
(This is on high, the battery only lasts an hour on high, Mid is still well enough which is about 30 lumen, so still brighter than the maglite, but runs for about 3 and a half hours, on low it goes for 16 hours, thats about 10 lumen, so still brighter than the maglite, so perfect if you was lost somewhere and needed to conserve your batteries and back ups)
I know you can not select charge on the nitecore, it chooses what is best for the battery, but I'm cool with that. I just trust Nitecore a lot more than Efest.
Plus its £23 vs £30+ that I can find for the efest, and that worldwide insurance policy just makes it seem more viable to me. I hope to never experience a fire using proper technique, but that would come in handy if it did go wrong, and I could not stop the spread of flames.
