Charges and powers almost all my devices easily.
Bought this to use as a single charger to charge my Macbook Pro (2018), Samsung Note 10, Mini PC, USB-C powerbank and other devices, both at home and out and about.It is a pretty good device, and using my cable with wattage display, can be observed to provide up to 87 Watts of power depending on the actual battery capacity, when only the mac is connected, which is bang on as this particular model of macbook will not draw any more than 87Watts regardless of the max available current. With other devices also charging this can drop to about 50-60 Watts, still more than enough.It charges my samsung at between 15 Watts and 22 Watts. Whilst this may seem low (the specs say up to 30W for that phone) the issue is the phone is very old at over 3 years old, and the charging system is restricting max charging to preserve the battery condition (this happens with the original charger too), however, it is detecting the faster charger being connected.It does get warm on high currents, but not exceedingly, the entire body is a heat sink.I do note that when you connect additional devices it does momentarily stop charging other already connected devices, but according to the specs this is expected, as it re-balences the power across all ports.its smaller (but not by much) than some modern laptop chargers but it does on the other hand provide up to four outputs and 100 watts, whilst most similar sized laptop chargers are usually 43 or 63 watt ones.I prefer the seperate power cord, as i generally dislike built in plugs, as they put a strain on the socket, and worse if I am travelling abroad they put strain on the adapter often falling out. With a seperate cord there is less strain on the socket/adapter, and indeed its easy enough to get a power cable for the particular country (its a standard panasonic figure of 8 cord). However, the seperate wire does add a little bulk which may be important to some.i do wish at its price it had some sort of display as to how much wattage/voltage is being given on each port.is able to provide my macbook with between 87 and 90 watts of power (with nothing else connected, according to my cable which has a built in display) I dont think this particular Macbook will pull more than that even though the charger can supply up to 100 Watts

Multiple USB C charge point
I was looking for a multi charger that I could easily carry with me and some cables to save on space and this one is perfect. Most were only shown g 2 ports but this charger had 4 which 3 are c type and 1 standard USB cable. I am impressed with the charge performance of the product and recommended to colleagues and friends to also purchase too.

Very fast charging
This multi plug is very fast charging and as there are 3 USB c charging points and a USB you only need to carry one plug around with the 4 wires. For me that’s Apple Watch, iPhone and iPad and my husband’s headphones.

Outstanding compact product
Wonderful for travelling. Power output sustains, doesn’t get over hot, easy to use, compact. Overall outstanding for its size. It powers an old 17” MacBook Pro with USB C and a converter to mag, with no issue at all.

Nice flexible charger
I am using this as a way to charge a laptop and a couple of phones, it works well, it is not perfect, usbc 1 and c2 should support the same specification of charge capabilities but it doesn't appear too, I have two Samsung phones and it only supports Super fast charging on c2 which is annoying as I would like both phones to have the ability to super charge but c1 does not support Super fast charging at all, it'll still do fast charging so it is not the end of the world, no doubt a firmware issue as the hardware is clearly capable of outputting the standard elsewhere and can supply a lot of current to the laptop.Nice device overall.

Does the job
Good quality product.Bought for use to charge iPad and other items.It charges my iPad Pro very quickly!Stays cool and just works. Wish I could say more but when something works as it should, there is only so much you can say.Four ports (2x USB C and 2x USB A)

Good value for money for a 40W charger
Bought this charger at the end of June and it was stationary in a particular room and not used daily.After a few months one of the ports completely stopped working. After contacting amazon customer care, I was directed to the manufacturer by amazon.The manufacturer has been quick to deal with and a replacement is on the way.Warranty from manufacturer wasn't mentioned in the listing but the manufacturer informed me that it is 1 year.For anyone buying, it is a 20w per port charger which is plenty for most phones.I will update this review after I have had some time to use the replacement charger and report back on its longevity.

Doubtful claim
I would like to dispute the sellers claim that it is 3x faster than a standard charger but this said it is a nicely designed piece of equipment and handy for charging 2 phones
