Anker is the best!
Color: Dark Gray
Another outstanding Anker product. They are such a step above in quality and fit than all the others. This charger actually has some heft to it making it feel very solid. The display is crisp and clear and shows temp, total charge and individual cord draw rates. I hooked up my iPhone 16 and Anker 21k mAh powerbank to it at the same time. Phone went from 48% to 90% in 20 mins, powerbank 0 to 100% in 1.5 hours. No overheating, worked flawlessly, highly recommend. Showed my friend, his comment was “pricy” but this is coming from a guy that just purchased and returned 2 other brands that he paid $30/each for because they were garbage. I buy the right product the first time, this has all the charging ports I need, is small and compact and tremendous value for the money. So buy cheap like my friend and return it or buy Anker and be happy for life! Some people never learn. ... show more

Compact, powerful, and finally a charger that tells me what’s happening.
Color: Silver
In the short time I’ve owned this 100W Anker charger, I’ve been thoroughly impressed. It has handled everything I’ve thrown at it so far—from my laptop and phones to various accessories—without a single hiccup. The standout feature for me is definitely the built-in smart display. It’s incredibly helpful to see the charging status in real-time. While I haven't sat and monitored every single watt, it’s clear the charging is working exactly as expected. Even though it’s an "Ultra-Compact" block, I haven't noticed any heat issues. The display does show the internal temperature, and while I don’t check it constantly, the unit stays cool enough that I haven't had any concerns. It feels like a high-quality, reliable charger that I hope to get many years of use out of. ... show more

The best charger on the market. Anker is the best
Color: Silver
Amazing quality, and you cant beat the price. I use it for my MacBook Air. Looks great and performs amazing. Charges super fast and is extremely stable. It’s compatible with a ton of devices. I would recommend for anyone.

This charger is just perfect, Anker always deliver excellent quality chargers and cables. This would charger my Galaxy S26 Ultra with no issues with fast charging 3.0 and my Galaxy Tab S8 with fast charging 2.0 simultaneously. Got this for travel and Multiple devices charging and this works wonders. The screen is so useful to see what wattage is currently using each device, temperature, usage hours and all the good information. Worth it! ... show more

Terrific charger for Macbook Pro M3!
Color: Dark Gray
I ordered this charger because I'm traveling with a smaller watt charger, which got too hot with my MacBook Pro M3. This charger is great! No heat and fast steady charging. It comes with a nice sturdy cable, and I've also used it with my longer Apple USB-C cable. This charger is smaller and lighter than Apple's version, but it feels well-made. The display works reliably. I'm very pleased with it. I would definitely buy it again. ... show more

Nice, if Heavy, Travel Charger
Color: Dark Gray
Works really well and while I initially thought the smart display was gimmicky, I’ve started to reference it more than I expected. It’s a lot more compact (and a LOT lighter) than the 140W version I tried first so if this is for travel and you don’t need the higher wattage, the 100 is the way to go. They’re both bricks in that they’re heavy for their size with what feels like good build quality, and I’m assuming the weight’s heat sinking, which should mean better heat management and longer life. On sale especially, I think it’s a good deal. One star off only because it is not light. ... show more

Great charger.
Color: Dark Gray
Great charger works really well and charges devices fast. It is very compact and weighs nothing. If it overheats heats it goes into cooling mode.

Awesome charger. Worth every penny.
Color: Silver
These are fantastic. It has a digital screen display showing how many watts are going to eat device charging. I bought this one after receiving another one as a gift. It comes with a USB C to USBC port as well as a USB a port. It can charge three devices at once and puts out at least 48 watts per channel. It comes with one charging cord that seems to be high amperage capable. My phone (rated for up to 68w charging, is fully charged within a half hour from a 20% charge. Love the brand and the charger. ... show more
