Quick Charging 3.0 USB Charger Adapter

This is a good pairing with the battery charger.

Works like a dream and now worrying about over charging different types on batteries. Fast charge is great. A+

Works as expected

It's ok, I'm using it on the UMS4 charger, nothing fast about it, it still takes all day to charge 4 - 18650 batteries.

Not much to say it does feel a little light

Very useful when you need to charge your batteries in a hurry.

This "Quick Charger" requires a USB-A cable. In the same order I purchased 2 batteries with built-in USB-C charge ports and a USB-C to USB-C cable. It's ridiculous they sent this charger. 1t's 2025. Best high speed charging is all USB-C. I contacted them to return for the proper charger and was informed they don't even carry such chargers. Weak.

Works as advertised 💯👍🏻

Little things awesome and charges fast I've had zero issues with it and will definitely buy again

It does the job well, like it promises

Works great

Wonderful

I have several of these QC3.0 USB charger adapters purchased both by themselves as well as bundled with UMS4 chargers. They work very well driving older (5V up to 2.4A) and newer (9V up to 2.1A) USB loads. I've charged everything from 2Wh headphones to 100Wh power banks with no problems. These charging adapters can get a bit toasty under high load but no worse than other QC adapters. Overall, very good and well worth the price.

Completes my order.

no complaints, bought this charger adapter as a dedicated charger for my numerous nitecore flashlights!

I picked this up for my MH10 V2 and its reliable and fast charging.

Works excellent just 2.5 hrs to complete charge.

I got this QC block to go with the Nitecore 3, cord I bought. Together they will be a back-up charging option.

Nice quick charger ~ it's just what we've been looking for!

5v @ 3 amp
9v @ 2 amp
12v @ 1.5 amp

It's a wall wart, but it's a really good one rated for Charging 3.0.

This charger works well with my UMS4.

It is a good part for my P20iX

Bought this for my UMS4 to enable quick charging capability. I keep it stowed together with the charger at home.

Charges light so very quickly!

Great charger adapter

I used charge adapter to charge my new Nitecore MH12S for the first time and 3 hours later it was fully charged

This 3 Amp. 110VAC Charger adaptor works very well with the UMS4 Nitecore Fast Charger. I have used it to charge 4 batteries at the same time, at the charge rate of 1000ma per battery.. Without using this adaptor, you can only charge 2 batteries at 1000ma at the same time.

Great when in an older building with out USB outlets installed with 120V outlets or away from your desktop computer/ computing device.
I would like to see how this device compares with other charging sources with regards to the units speed of charging devices. I have seen some devices advising not to charge with a higher capacity charger as it may damage the device. Can this charger sense how fast a device can accept a charge?

Compact, good quality.

Nitecore TIP2

Can't seem to have enough of these for various devices.

Great, high quality charger. Will purchase again.

You guys know you're good. Come on... :)
