18650 charger - 3 or 4 cells

[NickBose]

Is there any 18650 charger that can charge at least 3 or 4 cells?
With all those Luminus lights coming up that uses 3 cells (I can predict future 4 cell light too), I need such a charger.
Those who suggest using 2 standard chargers need not post here (Bringing along 2 wallwarts is absolutely not the idea)

AFAIK the main off-the-shelf options are a R/C style charger or two 2-cell charger -- naturally the hobby chargers are generally even larger than 2 chargers, and you still need a charging cradle or a set of leads with magnets, so I doubt they're a solution for you.

But if the cells are used in the same lights, they'll be in the same state of charge, so you can parallel charge any number of them on one charger -- have you considered just modifying a 2-cell charger by adding magnet leads so each channel can charge one or two cells?

Something like DX sku.6105 would be a suitable candidate -- it does use a correct charging profile, and can be modified from the stock 1A up to 1.5A or so. That would give 0.75A to each cell, which is as much as most 2-cell chargers. If you're main goal is to charge three cells, you could also combine the channels (with a switch, or permanently) and charge all three in parallel.
