Acebeam 21700 (21750?) cell-powerbank

[Agro]

Acebeam D20 flashlight comes with a cell that features an integrated powerbank

It’s called IMR21700NP-510A.
A cell with that product code is available separately:

15A Rechargeable 21700 Battery - 5100mAh (Non USB-C)

But it doesn’t have a powerbank (or even a charging port). :person_facepalming:

I asked Acebeam for more info, but they didn’t reply.

Does anyone known more about this powerbank cell? Seems like it would make an amazing combo with Acebeam EC65…….

I think the output circuit is in the battery and takes + puts out 5V when the cable is detected. Otherwise it would be dangerous to have output leads with the cell voltage in the micro usb connector.

Yeah, basically, there’s a 1A boost converter inside of the charging circuit.

I found a shop that sells them:
https://eu.nkon.nl/rechargeable/21700-20700-size/acebeam-21700-5100mah-20a-usb.html

20 € a piece.
Still, much cheaper than buying the light.
Also they confirm - it’s actually 21750.

What capacity does this cell have?
I don’t see anyone measuring it. But I see measurement of another “5100” cell from Acebeam:

21700 5100 mAh?

I bought three Acebeam 21700 protected cells from illumn with the 25% “spooky” coupon. Tested it in my Xtar Dragon Discharge capacity is 4,992mah, 4,922mah, 5,008mah. However, output of the C8F 21700 was measured at 2,400 lumens compared with 2,850mah with the Samsung 40T. I suspect Acebeam used a LG M50 or Samsung 50E under the wraps.
