MONITORMATE M2 Cube USB-C PD 1 to 4 USB Expansion for MacBook Pro's USB-C Charger(61W/87W)

Pretty nice product if you got multiple devices to charge while traveling. I bought this M2 Cube for my 2017 MacBook Pro 13". However, I thought there may be a risk if I use an alternative power charger which is not Apple-made, so I went to buy another 87W Apple USB C charger which is for MacBook Pro 15” after receiving this M2 Cube. Here is what I found the difference between using it on 61W and 87W charger for a couple of days.On 87W: I was able to charge MacBook Pro along with iPhone AND iPad at the same time.On 61W: I was able to charge MacBook Pro along with either iPhone or iPad at the same time.But I think this is expected because the MacBook Pro would need at least 40~45W for charging, and that makes sense if you take 45W away from 61W than you will have 16W left which is not enough for both iPhone and iPad charging.But honestly, it won't be a problem for me because I usually only need to charge MacBook and iPhone when I go out. Without charging MacBook Pro, both 61W and 87W work out just fine for all 4 ports.Let’s see how it goes.

Great product! First impression was so cool, and quality seems to be excellent. I like this thing could turn 1 USB C into 4 outputs — extremely convenient. The USB C does a great job with 13” MacBook Pro and QC3.0 charging with my iPhone X works well and fast. I could take my MacBook Pro's 61W charger with M2 Cube out and almost charge everything I need. Highly recommended.

I plugged it into my 29W MacBook charger and found out the USB-C port doesn't work.Went back to check the information and then realized that 61W or 87W MacBook Pro charger is what I need to make things right. I first tested it with my friend's charger (61W of MacBook Pro 13" with touch bar) and really work out. It does charge my MacBook and iPhone, so I guess I gotta buy one 61W charger for it. This product really does what it says. But we all know electronic supplies sometimes don’t last long. Hopefully this one stays what it functions! Will surely come back and update later if anything changes.

Was great then after a few days, it stops charging. Have to unplug and plug back in a few times for it to charge.

I like the USB-C passthrough and the ability to charge items like phones and Bluetooth devices without going through the computer.

Overall the attachment works. I had to add gaffers tape to hold it steady which looks a little odd. Also for some reason I was under the impression that the USB PLUGS connect to the mac but it turns out they are just power. Something that wasn’t obvious when I first purchased,

It is well made, almost looks like a product Apple would fabricate. But at the moment you connect it to an Apple charger to it it feels like a fragile connection and what is worst it randomly charges and very randomly works with Power delivery as advertised. Product is going back, doesn’t even work well with their own Square M2... I’m kind of worried because I just bought a monitor stand from the bran which is supposed to support power delivery... we’ll see about that

Hoping to get a replacement
