I certainly don’t need any more powerbanks but I suspected this one containing 3x 21700 so I went ahead and pulled the trigger. Build quality internal PCB board is pretty much generic, nothing remarkable to say. But it indeed contains 3x DBK branded 21700, it also came with a 3-in-1 usb cable, not so bad of a deal for $9.99. Testing on the MC3000 tonight
Edit: i just noticed it claims “UL Certified LG high density battery”
B&H has the Nitecore LA10 and LA10 CRI ‘liptstick’ lanterns for the typical prices ($24.99 and $29.99), but they sweeten it with a free Nitecore TUBE (black) keychain light. I just ordered one.
~94% of claimed capacity at 1A discharge/charge rate, for reference, Samsung 50E scored 4780mAh Max on the same test, but my MC3000 have always measured low
Manithree, I have ordered a similar Xtar charger on Banggood, but mine is the model VC2. There is a discount code to bring the price from US$15.99 down to US$7.99. I used that together with a VIP allowance of US$1. So, it came down to US$6.99, just like what Manithree paid on Amazon.
Curious to see why it was advertised as being a good charger for small NiMh AAA and AA cells.
Can’t wait to properly test it out at my friend’s house who lives out in the country. I also have the Sofirn BLF SP36 with 4x Samsung High CRI LEDs, and love it.
After 20 days of waiting, my Sofirn SF47 (4 x SST40) has arrived. I will try and get a mini-review out sometime this week.
Some notes:
It advertises 9000 lumens on turbo but I suspect that number is inflated. Unfortunately I can’t test this; can anyone weigh in on the theoretical output of two 21700 batteries in series married to 4 SST40 emitters? This uses a constant current driver.
This light has some decent heat-sinking and a very comfortably sized handle to hold onto. It seems like a good design for leaving a light on high output and not having to feel or stress about the heat.
I’m kinda curious what this light would be like with 4 SFT40 emitters.
Says they tested with 2x 5000mAh 21700 so that’s 37Wh
Also says Turbo is 1.5h runtime so on average it would be using 25W.
Nothing is doing 9000 lumens for 25W so they are not mentioning that Turbo means X seconds or minutes at XXXX lumens then the power is cut down a LOT but they keep counting the runtime on low power as “Turbo”.
4x SST40 can do 9000 lumens if the batteries can do over 12A in series for 90-100W which would suck the batteries dry in 20 minutes while burning your hand so instead it will do that for a short period then as the torch gets hot (won’t take long) it will cut the power down.
So for a short time, yes, it should do 9000 lumens.
Well step-down is no surprise; I’m familiar with the BS that is ANSI standards. I was just curious whether this could even hit that max output figure. Sounds like it should theoretically be able to. Thanks for the answer!
EDIT: Oh, hold up. The batteries are rewrapped Lishens (LR2170SD) so they are rated at 9.6 amps. I guess the light may under-perform with these cells. It may be two 21700s and a spring bypass away from greatenes
I was making fun of this today . But after having carried it it the woods and along the bike trail , I find it an oddly ,satisfyingly , legal club which is very comforting out in the dark places . It’s also a pretty decent light . I retract my ridicule.
