I would suggest the Vapcell S4 plus fast charger. It will charge at 3A on all 4 bays and give you a wide variety of options if you ever branch into other battery chemistries like lithium-ion 4.2 V.
It’s not been updated for a while but HKJ website has a very useful table of tested chargers.
If two slots is sufficient, look at the Vapcell U2. I’ve got one and like it.
Very minor downsides for me:
1) the ‘complicated’ blinky lights- there’s multiple colours on the display to indicate chemistry and charging progress, I find it’s a bit Christmas tree-vibe. That said, you don’t have to change the settings, you can just put an NiMH (or 3.7v lithium) in, and it’ll just get on and charge it.
2) It’s not the most “premium” of units, some of my AAA cells need a slight nudge when putting them in the slots to make sure they make contact with the terminals.
Ya I have an 8 bay Gyrfalcon that I love but it maxes at 1 amp. sometimes I have a 5,000 mah 21700 that I want to charge quickly and that takes a long time. The Vapcell detects a max current of 3 amp for it
I just bought a Nitecore UMS2 because it seems to have one of the longest charging bay lengths. That means it can do 21700 protected cells/ 21700 cells with built in charging. Maybe something to consider if you’re likely to branch off onto using lithium rechargeable batteries. There’s the UMS4 which is a 4 bay - I assume it can do the longer cells too? UMS2 Both do Ni-MH and Ni-Cd as well.
I’ve got a Nitecore SC4 I’ve had for years and it still works fine, but I had to mod it to fit unprotected 21700 cells and even then it’s a squeeze to fit them.
This is a good choice, just remember that some models of the chargers in this package with batteries are not independent 4-channel chargers, meaning, they have to be charged in pairs for it work.
Sorry I can’t remember the Charger’s exact model number that can charge 1 to 4 cells, independently.
The Vapcell is also a great NiMH-charger, I tested it with a lots of cells, also cheap and bad ones, it´s better in this that the most NiMH-only-chargers I have.
But it can´t charge NiMH @3A, that is what I mean. NiMH-charging is limited to 1A for each slot and it can´t charge size D cells.
If the Vapcell-price is OK for you I would highly recommend this charger
It can charge up to 77.8mm. It´s a 4-Slot(!)-version of the UMS2. UM2/UM4 have the same size but lower charge currents
The weakest point is the Slot-sharing, for me it´s more a 2-Slot-charger. For most cells I would prefer the Vapcell S4+. No slot-sharing, much better display, much more features (the UMS4 can only charge), more reliable for NiMH.
