USB power bank box that takes my own batteries (need not charge them)

[lumen aeternum]

I want a USB power output "box" where I can use my own batteries and charge them externally. Two 18650s would be enough.
EDIT: by "externally" I mean all I want is regulated power out, not a charger.

XTAR DRAGON VP4 Plus. Other XTAR chargers can also act as battery-powered USB banks.

I know of the XTAR PB2(s) and Nitecore F2 that both act like charger and powerbank. Both work with 2x18650.

Armytek chargers work as power banks 1,2 and4 cell

Just get an Xtar PBS2 for ~$15-$17 and be done with it.

Bonus points if you pick up some 21700s to go with it.

Don't know if it's regulated but the PB2 can only take flat top unprotecteds.

I have used a single-cell Fenix LiIon charger with a USB plug to charge my smartphone using any 18650 etc.

Am not sure of the model, but I could take a quick pic if that would be of any assistance ?

batteries need to be covered.
Anybody know where to buy a battery holder that is encased fully? Hopefully with a USB jack for output? Otherwise I can add wires with the appropriate jack.

The XTAR PB2, PB2s and PB2c have the batteries fully covered inside the case.

The PB2c can take flat or button top and protected or unprotected.

So many of these powers bank shells in Banggood, I do like the 2-way pd 18w charging/power sharing.
