1. Although Efest batteries are disdained because of inflated ratings, Efest LUC chargers have been held in high regard.
2. "Compatible with most sizes of cylindrical lithium-ion batteries ranging from 10440 to 26650." -- RTD Vapor

3. According to Mooch:
- Charging at a slower rate is better, to a point. Most of our 18650 batteries have a "standard" charge rate of 1.0A-1.5A and a "rapid" charge rate of up to 4A. Charging at 0.5A might help extend the life of your batteries a bit but if the batteries are not getting warm at 1.0A then that's a good compromise between battery life and convenience. Going down to 0.375A or 0.25A won't help much versus charging at 0.5A.
- Charge 18350's at 0.5A until you know that they aren't getting more than a bit warm.
- Charge 26650's at 1.0A until you know that they aren't getting more than a bit warm. The better 26650's can be charged at up 2.0A without adversely affecting battery life. -- How can we extend the life of our batteries?

2X700 batteries are a tight squeeze. They can fit, but you may damage the wraps if your not careful. I have used my luc6 for 2X700 batteries for a few months, but recently got a new xtar charger for them as they fit with room to spare.
I have been using my LUC4 for over 4 years now. I have multiple dual battery mods going at one time and am constantly recharging. Never had a problem with the charger. Highly recommend it. I use 18650s only.
The Luc V4 is a very reliable charger for xx650 cells and I had it in use for a very long time, but its bays are too short for 20700 cells imo. Although you can squeeze them in, it's just a pita and it may damage the wrap/insulator, if you're not very careful.
If 1A charging is fast enough for you, the Enova Gyrfalcon All-44 might be worth a look. I'm very happy with mine at least, and online reviews have been very positive as well.

I'm surprised that so many are saying not to charge 20700 cells in the Luc 4. I do it all the time and haven't had a bit of a problem. I don't see how they could tear your wraps unless you're jamming them in carelessly. But that could happen with 18650s as well. It's a good idea to always carefully insert batteries in a charger and keep an eye on them while they charge.
I have the Efest Luc4 and purchased 2x Vapcell 20700 in Jan.
They only fit in the 3rd and 4th slot on mine, and they are a tight fit, but haven't torn up my wraps.
My charger is a couple of years old.

They do fit, if you insert them perfectly straight from the top, but nowhere near as comfortably as into the Enova for example.
On my luc 6 it is a tight fit. The metal slider has to be extended all the way for a 2x700 to fit in, and when the battery is in there the slider cannot be pulled back at all to release the battery when taking it out. So I will have to stick with my initial response and say that 2x700 batteries do fit, but it is a tight squeeze and that can make it so your battery wraps can get damaged if your not careful. My xtar charger has enough play in the slider that I can pull it back about 2mm which I can then comfortably pull it out. Attached is a couple pics of a 20700 in my luc 6. Second pic is how much room there is between the slider (you can barely see it but it is the shiny part under the battery) and the plastic frame of the charger when a battery is installed.
I've had my Efest Luc v4 for around a year or so,it's been used daily (18650's) since I purchased it with no problems at all.Well worth the money spent in my opinion.
