Help needed with a pulsar N550 night vision unit

Hi, hopefully there’s someone on here who might be able to help me . I’m trying to make up a rechargeable external power pack for my pulsar N550 as they don’t sell them for that model anymore.
Is there anyone on here who has a power pack for an n550 that could advise me of the pulsar power pack output rating ? Or someone who’s made one for theirs?
Kindest regards, Olaf
 
N550 was/is compatible with EPS3 and EPS5 packs. EPS5 is 11.1V 5Ah. Charger is 12.6V 2A.

Pulsar still gives some specs for those packs, but not very informative:


Easiest solution might be suitable transformer / power supply, connected to USB powerbank. Or holder for 3x 18650 in series (charge them separately in battery charger).
 
Thanks to both of you. Your answers confirmed how I dealt with it in the end . All Sorted now . I’ve made up a couple of rechargeable 13 v ish bat pacs and it works really well. It needs 9v minimum to work with an external power supply, despite the unit only needing 6 v from its internal battery power supply.
So, I’ve slapped some rechargeable battery pacs together now and it’s a happy camera again.
Thanks once again for your kind help.
Kindest regards, Olaf

4x 18650 bats seem to do it rather nicely now. I can use them for other applications too as and when.
Thanks to you both for your kind help.
Kindest regards, Olaf
 
Be aware that fresh 18650 is about 4.2V so you get over 15V in series.
Thank you kindly for your help, I’ve measured it and it’s only giving a bit over 14 v . I’ve used it all day today and it seems to be doing a fantastic job now without having to fiddle with the little AA batteries.
Kindest regards, Olaf
 
I made my own in the end. Why? Do you own an n55o . There’s other more simple ways to supply power to it externally that don’t involve making an external battery, I just did so as I needed a specific size and shape. Lmk, if you need any help with it.
Kindest regards, Olaf
