Good review, good music, good use of speeding up shots to get to the relevant parts quicker. Nice job!
As always the coolest review on youtube....
I am likin' this style of unboxing. Sped up the insignificant bits, slowed down the important ones 👍
Thank you, I got the information I wanted, before purchasing this product.
Excellent review! Gabb free.

Smooth review, should I choose Nitecore ums2 or Xtar vc2s? Thank you for your answers.
This would be great to throw in my pack!😎😀
Awesome...
Great review. Very succinct. It's a pity that people need to be reminded to lubricate moving parts though. Subbed.
Thank you.
Yes, nowadays the maintenance is forgoten by people...
I use DRY LUBE SPRAY........a suggestion no dust and dirt collects, nor running from heat. I have a D4 same thing grinds a bit. Bought the D4 when they first came out many many years Go. It's still is working without problems but it's a slowwwwww charger. I use it daily on 18650's and believe slow is good to the battery.
Thank you for the advice.
Yes, me too I still use the D4, slow is better.
Does the USM2 LCD screen DIM after 10 minutes & is the dimmed screen REALLY DARK or just a bit dimmer compared to the normal LCD brightness ?
No, it remain normal brightness for all the charge time.
I heard that after plugging-in and un-plugging the USB cable from this device that the USB port quickly gets loose and the device breaks and stops working because the USB connector soldering points are the only thing holding the USB port in. Is this true? This device overall seems very nice but if the USB connector is poorly held together or poorly installed then I do not want to buy something that is going to quickly break. Thannks in advance if you can help me answer this question!
I will unmount and take a look. See you later.
Hi, I disassembled the UMS2: the USB port is hold by 2 soldering point and 2 pins on the electronic board. To my point of view it looks strong enough because I tried to force the USB port with my nails and it seams tough. I think to break this microUSB port you need to plug an USB cable and leverage strongly, which is not normal.
I hope I helped you.
@@SirioSechi wow thank you so much for you taking the time and testing this for me! :) That was very kind of you, and I thank you very much for your answer and help! I will purchase one of these now with much more confidence. I hope that you and your loved ones all stay healthy and safe during these difficult times!
Hi may i know compare from xtar v2 with nitecore um2 which charger better? Cos I’m planning to buy a xtar v2 because it come with 0v charge function..tq
I don't know. I just know that Xtar chargers are very good.
good
Hello,
I have a doubt that I would like to clarify.
I generally use my UMS2 to charge Ni-MH battery types, recently I purchased a few USB rechargeable 650mAh 14500s and I observed that the batteries charge in almost 2hrs 40mins using a 5V 1A power supply with USB cable and nearly 2hrs with the UMS2 charger but after the charge reaches 650mAh the charger doesn't stop unless it reaches 4.2V. So is it ok to charge the 14500s till they reach 650mAh because I thought charging the USB rechargeable batteries with an Intelligent charger would likely extend the life of the battery compared to a constant power supply when every possible and while traveling I use the USB cable way. So which is the preferred method to charge USB rechargeable batteries to extend the life.
Can you set it to charge at a current of 290mA? I need it to charge a gumstick battery whose max charge is at 290mA plus it needs to take its 66mm height. Looks like it can take up to 70mm height?
Cool review, thanks.
200 or 300.
Long press the C button to enter the Charging Setting Mode;
Short press the C button to switch to different setting parameters: Charging current and Cut-Off voltage.
Short press the V button to increase with a 100mA increment each time when setting the Charging Current.
Long press the C button to save and exit the Charging setting mode.
The maximum aperture is 78mm, then yes, the 70mm batt will fit in.
@@SirioSechi Awesome, thanks!
Merci
Il n'y a pas de quoi. 😊
Also, Vaseline is an EXCELLENT fire starter. I dont know why youre using that as a suggestion lol
Come on, is not like benzine. Especially on metal and a fireproof plastic nothing can happen. The quantity is few that nothing can happen. But if you want the next time I will suggest silicon grease. ;-)

Nice review.
Btw. I have one question.
In input 18W (MAX). What if i use 20W? Is the quick charge in Nitecore UMS2 will turn on?
What is the source who gives 20W?
@@SirioSechi i'm just asking, Sir. So, the input of this charger is 18W (MAX). it's mean Nitecore UMS2 only recommended 18W for safety, Sir? Not recommended using 20W? 🙏🏻
Nitecore ums4 or Liitokala lii-500?
Sorry, I never tryed the Liitokala lii-500
Won't the Vaseline melt then short circuit the charger ?
No, just put it on the plastic slide, a thin layer. Not more.
@@SirioSechi Does the UMS2's LCD screen turn off after 10 minutes of inactivity ?
@@SirioSechi My USM2 charger just arrived but I noticed it's LCD screen Does not turn off by itself even after 10 minutes of inactivity or after not touching any buttons of the charger... it's supposed to turn off Right?
Will this work on protected button top 21700?
Yes, the 21700 battery fit and charge perfectly
I noticed some come with and without the 3.0 "fast" wall plug. I figured all of them would? Good thing I looked into that!
@@DenzDezignz My UMS2 is powered only by microUSB
@@SirioSechi but I like to have that quicker option if needed. I'm apprehensive of not being good on battery
@@DenzDezignz I don't know about this wall socket power version. Mine is only by micro USB and it works fine. Just put a good charger, al least 2Ah. And a good cable.
Please what is the UM4 and UMS4
The difference between UM(S)2 and UM(S)4 is, UM2 has 2 batterie slots and UM4 has 4 batterie slots.
Esto NO es ningun test , esto no demuestra una buena function del cargador
Speak up
Don't need
crappy product, 1st slot stoped charging after a few uses.
Bring it warranty
@@SirioSechi i dont keep papers or box, otherwise my house would be filled with those...
but i bought many times from that site, 5 Nitecore flashlights, 2 chargers, some 18650, knifes and more flashlights and items i dont remember now. anyway, Nitecore and that site lost me as client. the other charger, Nitecore F1 does not work either, and they didnt replaced it. its their legal right, i dont have the fiscal bill. i lost some money, they lost alot more money from me.
anyway ums2 is crap, rechargeable AA and 14500 position must be manual adjusted to start charging. in normal position is no contact. so crappy product anyway.
@@randomescu guess you're one of those umlucky ones then
@@aggaviriyo790 kinda, its my fault i dont keep the fiscal bill and the full box as they ask for refund, repair or replace. sadly im not gonna change that.
@@randomescu so what brand are you using now?
crappy product, mine broke in a week.
