Yes, 26800 fits. I charged a QB26800 at 5A and posted a graph above.

Thank you for the great review.
I’m getting two of these next week. I will not take my battery out while it’s charging. 
That should not happen but I thank the member who mentioned that.
I will definitely use the three amp option A lot. Four or five amps for some of my 21700 when I’m in a hurry.
I have data sheets for most of my batteries. It’s surprising how many amps some of them can take. But that will obviously lessen their lifespan. I was shocked to see the P28A can take 8.4 amps! Maximum charge rate.VTC5A/D 6A,Samsung 50S 6A, Samsung 25S 4A.
I don’t charge any of those more than 3 amps.

thanks! i just wanted to be sure
Simple Auto CH1 3.6V Li-ion #4
CH1: XTAR 18650 3.6V Li-ion 4000mAh (button top)
| Measurement | CH1 | CH2 |

| Finish Voltage | 4.159 | |
| Capacity (mAh) | 3964 | |

I selected Simple and Auto modes to charge an XTAR 18650 cell from 2.922V to 4.159V. It took just under 3 hours to charge.
The charge current started at 3A and it gradually decreased over time. This is the maximum charge current in Simple mode.
I measured 4.159V a few hours after charging finished.

Pro 5000mA CH1 3.6V Li-ion #3
CH1: Molicel P45B 21700 Li-ion 4500mAh (flat top)
| Measurement | CH1 | CH2 |

| Start Voltage | 3.000 | |
| Finish Voltage | 4.190 | |

I manually selected 5000mA in Pro mode to charge a Molicel P45B 21700 from 3.00V to 4.19V. It took just under 1 hour 30 minutes to charge.
The surface temperature of the charger near the positive terminal and the cell reached a little over 30 C.
I got two of them today. Both of them are defective. In Pro mode /manual settings, the charge rate continues to flash and so does the battery type at the top.
In simple mode it does not do that. I did not see anything in the review that warrants this. I guess I’ll be using simple mode because it’s very annoying. And I still haven’t confirmed that it’s actually charging them.
20 minutes later and voltage didn’t go up a hundredth of a volt. They do not charge in Pro mode
I think I’ll stick to the s4!
One other thing… They never gave me a confirmation email. And I let them know. All they did was send me a tracking number. And it was wrong the first time after 5 days I figured that out! Then they sent me the correct one. But again never sent me a confirmation email I have never experienced that with any dealer.
My Bank just refunded me.
That’s unfortunate. The s4+ is great
It is.
Glad I have a good bank. Still works in simple mode so I got two free Chargers in simple mode
The backlight stopped working in mine. I received a replacement a few days ago.
I’ll continue doing a few more tests and then finish the review.
I suspect that the JST* power connector for the display was loose.
You need to hold the second button in Pro mode to start charging.
Thank you. I reread it and saw you mentioned that at the end of the review. My bad.
One other thought. I guess someone with electronics background or VAPCELL could answer this.
You have a switch to change to pro mode why would you have to do something else?
I’ll update the first post and also post my final review on my blog once done. Apologies if this format is a bit confusing. Part of the review is in the first post and then I have posted graphs as replies.
Thank you.
Anybody? How do you quote someone on this website? I haven’t been able to figure it out. Thanks
There are two ways to quote someone on BLF.
You can click on “Reply” to the post that you want to quote, and then click on the text bubble in the top left corner or the post editor.
Or, you can select/highlight some text with your mouse/finger and then click on “Quote.”
Ok. Thanks…
I had to do what you told me and then hit the three lines in the top right and then that opened up the text bubble I just took a guess and that’s how it opened it up.
1 Thank
Thanks this time it worked and I didn’t hit those three lines.

Thank you everybody. That’s my last practice quote.
