Do we know if the fan is quieter now? He says there’s a new fan cover, but does that effect the noise?

Yes, the fan is quieter on the 2.1, and as pointed out to Henry, you will notice that the new fan now has three-leg bracket for a more rigid fan protection against mis-alignment against the shroud.

Will this have UL/CE logo and reference number?

I doubt it would make it quieter based on cover alone. IT was the fan itself that was making the noise i think.

Henry has mentioned about a new lubricant in one of his previous posts in the gb thread but I can’t find it now. He has been aware of the fan noise complaints.

Think going to order this with batteries. What’s the difference between the blue and red 26650 6000mah tangsfire batteries?

Not only the charger, the power plug does also show a CE logo.

If you are to source your 26650 cells from Gearbest, better take the Soshine brand of 26650 batteries. Tangsfire brand are relatively of unknown quality.

When is Gearbest going to get proper batteries?

is there an (auto) 4.35V switch? or do you still have to open the case

The case still has to be opened, but very easily by taking off the 4 screws, then the whole bottom is exposed, including the selector. Just a two-minute job.

Actually I have brought this issue with Henry Xu, the designer, citing the VP2 design as an example. His logic in putting the selector inside is that with the selector outside, there is a very high chance of it being inadvertently or accidentally switched to another selection and can be dangerous to a new user. (of which I personally agree) Imagine accidentally switching to the 4.35V selection for a 3.7 LifePo cell to be charged. It happened to me one time when I was using my VP2.

Does this do LiFEPO4 charging also? Their description says “3.7 Li-FeO4”.

Also, if yes, does that have to be selected with the same internal switch you mentioned, and then do all 4 bays only do LiFEPO4?

The internal switch has 3 selections: 3.7V, 4.2V and 4.35V, and all bays will be affected according to the chosen terminal voltage selection in charge mode. Its default is 4.2V

Thanks to you and all the others who brought this to this point. I’ve been lurking for awhile and definitely on the fence with the earlier versions, but this one sounds like it might a winner. I still want to wait for HKJ’s review though…

Thanks again!

Could they use a key lock switch? That would be much more convenient than disassembling the charger each time and prevent accidents as well as an internal switch. I have no idea if it would be economically feasible but I'd be much more likely to buy a charger I didn't have to disassemble every time I wanted to charge a different type cell.

I’m sure the switch has 4 legs to it, a common power and three grounds for each position. O’Reilly’s [or any good hardware store] should have at least one multi-position rotary switch. Finding space for it might be interesting, it would require some fine soldering, but it could be made to work.

That’s great to know. Would you be able to share how many have been sold already? And how many pieces are actually allocated to the first shipment? Thanks.
