Is it fast charging for both the usb-c and the usb slots?
New User U
on Oct 16, 2018
BEST ANSWER: The USB-C charging doesn't max at the 100W power delivery limit but does charge most non-laptop devices at full power. The USB-A charging maxes out the spec for that type: 5V x 2.4A = 12W so it will charge as fast as it can within the spec.

No, the USB-C supports PD, which negotiates fast charging at 9V and 12V (plus the laptop modes up to 19V). USB-A is just a 5V 2.1A, which is good enough for tablets but not true fast charging.

the usb-c is super fast... but the usb (regular) is a little faster than say a simple one for your car, if that makes any sense

Does this work with a Macbook Pro - 15" - 2017?

BEST ANSWER: Yes, though it'll be a trickle charge if the machine is powered off, and may still drain the battery if under heavy use.

Since the 15” MBP will charge, though very slowly, with a 30W MacBook 29W charger, I’d have to say very probably

Will this work with the new 13" Macbook pro and would it work on 240v (Europe/Asia)? Thanks.
Asif B
on Feb 15, 2018
BEST ANSWER: It does charge a 12" MacBook properly. I tried it with a colleague's 15" MacBook Pro and while it did charge, it was very slow. Given that the 14" MBP uses a 61W power adapter, this one is likely to charge it very slowly, so is not recommended.
Unlike the Apple adaptors, the plug is not removable, so while it will work in Europe electrically, you will need a plug adaptor.

This does work on 240v with the appropriate plug adapter, and the 13" MBP does work with the 15V/3A USB-C PD profile so it will probably work. However, I have seen this charger disconnect once the host reaches a 100% charge so you'll have to watch out to see if a MBP will stay topped off at full charge.

Are the USB-C and USB-A ports independent? On my current non-Monoprice charger, the USB-C power slows down from 18W to 10W if I plug something into the USB-A port.
Chirag P
on Jan 15, 2019
BEST ANSWER: I have no way of actually testing the power coming out of the ports, but empirically, there seems to be no slow down when both ports are used. I often charge my iPad Pro at the same time as I charge my MacBook.

MacBooks have specific requirements for USBC charging and will not allow a charge with all generic chargers. Sometimes MacBooks will charge at slow rates, in other cases, MacBooks will not recognize the charge at all, and will not take any power. Will this USBC charger charge a MacBook?
A shopper
on Jan 5, 2018
BEST ANSWER: Yes, the MacBook will charge at its maximum capacity of 29W with the 39W Dual USB Wall Charger. That was a key focus for us, and is also a big advantage of offering a USB-IF certified charger.

Defective port.
The USB-A port did not work at first. I tried different cables to make sure it?s not a bad cable. The charged my iPhone XR very very slowly now. I do not consider that to be functional normally.

Solid Charger
Built like a tank, tight connections, quick charging with no heat. Have many Monoprice branded items and like all of them, this one is on another level for the price. Keep up the good work!

Plug should have been longer.
Charges quickly and appears well built. Only complaint is the plug is short and can fall off the wall if touched.

Great charging block.
It was a great idea go buy this for roughly 10 bucks on sale. And it fast charges my phone using the USB C. Using a Samsung s20 fe. Definitely want to buy another if on sale again.
