SIIG 240W USB-C 4-Port PD GaN Charger 3C1A PD 3 1 QC 3 0 Fast Charging for MacBook

It seemed to work at first. Shortly, after the return window closed, I realize that the middle two ports didn't work. I didn't see this as a huge dealbreaker, as I mainly just use the top port for charging my laptop, and only use the middle two ports when traveling. So what I just ended up doing, was just charging with my laptop with the top port and then using the ports on my laptop to charge my other devices. When I was getting a new charger to replace this one, I also got a power usage meter so I could confirm the power usage on the new block, because I had read some reviews that the speed weren't as advertised. I measured the speeds on this unit, and realize that the top port, which should be 140w, was only delivering about 100w (90-96w). The power meter confirmed indeed the middle two ports did not work at all. The bottom Port was giving around 10 W. Just recently, the unit stopped functioning altogether. No ports deliver. Any power any longer. I would have expected a charger of this price point to last much much longer than the 14 months that it did last. Contacted SIIG for RMA and have not heard back yet. Read more

This thing works like a charm. It does exactly what it says it'll do and my wife and I are tired of searching for separate chargers. We move around a lot in our home, to our offices or to our couch and kitchen, and often we'll need to run upstairs or downstairs to find where we left our charger. I wanted one for the living room where we could both sit on the couch, charge our phones and laptops at the same time and not require a bunch of different chargers. This does that job wonderfully. It doesn't get as hot as the other chargers either. Note - between my wife and I, we have 6 Mac Books and 2 iPhones, so this is why it's really kind of a pain for us. Long story short, the only thing bad about this charger is the power cord and how short it is and how easy it falls out. I wish it was a bit more snug in the back and I wish it was a bit longer, like 2-3 feet longer. Either way, I can deal with it... Everything else is perfect. Read more

DO NOT PURCHASE!!!! It starts off working and few months later none of the ports work to charge anything. Waste of money! Read more

I really prefer my charging bricks to be grounded. After getting shocked from my laptop a few times you know since it's metal. I decided I wanted to get a grounded power brick. Usually I use the Apple one with the extension which they now sell separately but with USB-C and multiple devices using that standard it makes more sense to have something with more than one port. This seems to fit the bill and works for almost everything except I find I am very careful about what I use it on. This cannot be used for anything I mean anything that connects Audio to a sound system. It does not filter the power properly and Causes hash noise and anything that shares power from this and an audio connection. No using wireless microphones while charging no using laptop well plugged into mixer no using well using OBS and streaming. I've had to label mine do not use with audio devices. As long as the downstream device is not in use it charge is fine, in use and charge is fine, in use and passing audio = noise! I was streaming and the replacement power brick for the computer I was using for graphics on the projector hadn't come in yet so I was using this. Even though that system was only connected through everything else HDMI and USB to HDMI capture card and Audio to the mixer the only way to get rid of the noise was to unplug it from power and switch to a different power brick. Other than that it charges everything really well it's just really hard to not grab it and then scratch your head for 10 minutes wondering why there's terrible noise coming through the speakers when is seems like such a good quality product but they skimped on one little bit of it. I almost would've bought another one. Would've preferred a black version White tends to get dirtier. So instead I bought the OTAO newer version of the other WOTOBEUS one I got which has no problem. And this one is just my lives in bag for charging other devices on the other side of the room charger, and used in places where grounding might be necessary. Read more

This thing is fairly bulky and heavy, and feels solidly built. That's reflected in its performance. It delivers well in excess of 100W on the primary output (current limiter seems to cut out at 20V/6.4A). Running continuously at 100W load, the charger gets warm but not uncomfortably hot. It's plenty capable of charging a large power-hungry laptop or tablet, with capacity left over for a flagship phone and a couple small devices. The additional USB-C ports are capable of delivering another 100W on port 2 and 65W on port 3, and the USB-A port supports QC2.0 and QC3.0, delivering up to 20V/60W. Unlike many adapters, the ports seem to be completely independent, plugging devices into one port doesn't disrupt others. Total power rating is 200W, which it seems to be capable of delivering. It does get quite warm doing this continuously. Fairly efficient, too. According to my Kill-A-Watt, the idle power with no load is 2.5W, and the input power while delivering 100W output is 115W. It's not cheap, but if you need this kind of power, and are looking for a solidly built charger from an actual name brand, here it is. Read more

This charger is big and feels solid with sturdy construction. My phone was charging at 7.2A when plugged into the USB C port. It can charge both my phone and laptop at the same time. This charger is much more efficient than some of the multiport USB charger that I own. This is a good charger, a bit heavy, and may be good fit for travel with these extra ports. Read more
