current best prices on AA/AAA and LiIon 4 port chargers

Hi- I am posting this because of the vast nature of BLF. I can’t keep up with all the posts. In all likelihood, I would miss some of the deals/discounts/coupons that are available, so I am reaching out to the group.

I am looking for a charger for my Mom, who uses AA and AAA NiMh batteries. It also needs to allow for charging an odd number of batteries (a “smart” charger.) Simple and reliable are musts. I have added the LiIon feature in case I am visiting and want to charge an 18650 or 16340.

The chargers I have identified are these:

Xtar vc4

Nitecore D4

Liitokala lii 500

Opus BT-C3100

What are the best deals going on these units, and are there any others in the same price range that are recommended?

Thanks!

Bob

XTAR VC4 was going for $16 at GearBest yesterday. I almost got one, but I use only AA/AAA and this charger doesn’t discharge/recondition them and also don’t display voltage digits (they have a digital graph instead). Keep in mind that this is a USB charger so you have to use some smartphone wall adapter or order the XTAR one separately. Some people claim their adapters are not strong enough for the maximum charge rate. I’ve read some people complaining about innacurate readings and I changed my mind about buying one.
