Test/review of Charger LiitoKala Lii-402

Thanks HKJ. :+1:

Thanks for the review. I recently purchased this charger and I really like it. It’s nice to see it perform well in your tests.

Thanks for the Review!

So you can’t charge 4* 18650’s @1A at the same time(?)
I tought it would be a nice charger besides my lii500. But this is a no go.

I believe that’s the limit of a USB-powered charger (5v 2A).

I wonder if a 5v 3A USB charger (5v3A is out of spec??) would be able to do faster charging if supported?

This is a bit of a gray area. Apple coding support up to 2.4A at 5V, QuickCharge is usual up to 3A at 5V
Usb charger (DCP) is 1.5A or maybe more.

Thank You for taking the time to do yet another GREAT review.
I might not understand all of your test but I am slowly learning.

Thank You

Hi all.,

I’ve just ordered this charger at Rosegal with a code DSRGMY18 which gives the price at $6.99 including free shipping.

Hate to say it, but it’s the worst charger I have ever had. Oh, you can get by with it….but there is far better stuff out there.

I received my own copy and i just can say: great charger!

It’s a great backup charger; very compact and micro USB powered. If you have a backup light with you, why not a backup charger just in case?

Does Lii-402 have battery checker like lii100 and lii202 ?

Put a li-ion battery when charger not powered and it will display current battery capacity on 4 dashs ?

Yes, it does that too.

On one slot I suppose not on all ?

Yes, on the most right slot only.

Thanks guys !

Cheers vid. I was pleasantly surprised by the quality of this charger for the money. It’s not perfect though, terminating voltage of the four bays vary significantly. Last time I charged four identical cells simultaneously the lowest terminating voltage was 4.10V, and the highest was 4.19V. But for the money it’s awesome!

Try again with the same cells and swap their places and see maybe one same slot is problematic.

I think about half a year ago this wasn’t the case, so I was under the impression it was sort of random. Also the voltages of the other three slots were not identical as is the case for example with my Xtar VP4. But I’ll pay attention to this next time. :+1:

If you mean, when the Lii-100/202/402 chargers are not connected to USB power, and you put a battery on the battery slots, will the “4-dash” level bars light up to indicate approximately how many percentage charged?

So, when the Lii chargers are not powered via micro-USB, that “function” works only when there’s a battery on the right-most slot (only the right-most slot has the USB powerbank function). So when the right-most slot is occupied, the other slots with batteries will then indicate their battery charge level. But if the rightmost slot is not occupied/providing power to the device, then the charger doesn’t power up — all other slots will not light up.

An observation: the Miboxer C4-12 also has this same function. When not connected to AC power, but the C4-12 has a lithium-ion battery on the rightmost slot (powerbank function), the other 3 slots (with battery inserted) will then show the idle voltages (the 4th slot itself won’t show voltage of the 4th slot, but instead shows the current consumed by the USB powerbank function)
