Anker Power Bank, 20,000mAh Travel Essential, Built-in USB-C Cable(Black) | 1 USB-C and 1 USB-A port, for MacBook Pro/Air, iPhone 17/16/15/14, Samsung, Switch and more

This power bank has been one of the best purchases I've made. I originally bought it for backpacking the Devils Dome Loop Trail so I could keep my phone and headlamp charged, and it worked flawlessly throughout the trip. After using it in the backcountry, it quickly became something I carry with me every day. My iPhone 13's battery isn't what it used to be, so it's nice to have a reliable way to top it off whenever I need to. It's also been great for my camera gear. I regularly use it to charge my GoPro and Canon camera batteries, making it a great addition to my photography kit as well as my hiking gear. One feature I really appreciate is how quickly it charges both itself and my devices. The built-in USB-C cable is also incredibly convenient since it's one less cable I have to remember to pack. Overall, this is a high-quality power bank that's been reliable whether I'm backpacking in the mountains, traveling, or just going about my day. It's well built, charges quickly, has plenty of capacity, and has easily been worth every penny. I'd definitely recommend it.

I’ve been using the Anker 737 Power Bank for a few weeks now, and I’m genuinely impressed by its performance. As someone who relies heavily on their devices throughout the day, a powerful, fast-charging power bank is essential. The Anker 737 does not disappoint! Charging Speed: The standout feature of this power bank is its speed. With a 140W output, it can charge my phone, tablet, or even my laptop at impressive speeds. I’ve tested it with multiple devices, and the USB-C Power Delivery port ensures my devices are charged up quickly, even with high-power needs. Charging my laptop was smooth and hassle-free, which is something I haven’t been able to say about other power banks. Capacity: With a 24,000mAh capacity, this power bank can charge my phone multiple times before needing a recharge. I’ve used it for a weekend trip, and it kept my devices powered throughout without needing to plug it back in. If you’re someone who travels a lot or is often on the go, this capacity is perfect for keeping your devices running throughout the day. Design & Portability: Despite the large battery capacity, the Anker 737 Power Bank isn’t bulky or cumbersome. It has a sleek, compact design that’s easy to carry around, fitting into my bag without taking up too much space. The matte finish is also a nice touch—it’s easy to grip and doesn’t show fingerprints, which is a plus! Build Quality & Durability: Anker has always had a reputation for high-quality products, and the 737 Power Bank is no exception. It feels solid and well-built, with durable materials that can handle daily use. I haven’t noticed any signs of wear and tear, even though I carry it around regularly. Additional Features: The LED display showing the remaining battery percentage is a handy touch. It’s so much easier to gauge how much charge is left, which helps me avoid the dreaded "dead battery" surprise. It also has multiple ports, so you can charge more than one device simultaneously, which is a huge time-saver. Conclusion: Overall, I highly recommend the Anker 737 Power Bank (PowerCore 24K) to anyone who needs a reliable, fast, and powerful portable charger. Whether you're a frequent traveler, someone who works on-the-go, or just someone who hates running out of battery, this power bank will meet all your needs. It offers fast charging, a high capacity, and a sleek, portable design. For the price, it’s definitely a solid investment!

Great power bank. I have already been using it for basically a year without issues. It is big enough to maintain even my laptop for an hour when needed, but still small enough that it is allowed in my bag during flights. A tip if you are charging something using low voltage and see the charge stops after a minute: Double press the big button on the power bank to put in in "low voltage charging" mode. You will notice a green leaf in the screen. Basically, some power banks don't fully detect the request for energy from small devices that use low charging rates. You need to enable it for those. Ps: the power bank itself is quite heavy

This is a great power bank! It has built-in cables and is compact and powerful. It's a little on the heavy side but it works great and it's easy to re-charge.

Awesome and powerful. It charges other powerful devices such as the iPhone quickly and it charges quickly with a higher voltage transformer/plug. At first, I thought that the power bank might be a bit bulky and heavy, but it would fit in a pocket and charge my iPhone and other devices--so a good size. I purchased too many other power banks that claimed to be powerful and portable, but while they were more portable, the power was seriously lacking. I love the built-in USB C cable design; there is no need to carry a separate USB-C cable when you are in the airplane or on the road. The display clearly tells you the percentage of charge remaining.

We needed this for a cruise since there is only one AC power outlet in the room. Charge during the day and then let it do its work at night on our bedside. Don't have bedside AC outlet, this is a good solution. Battery takes a while to charge but it has LOTS of juice.

have owned quite a few Anker products over the years, and this 20,000mAh Power Bank might be one of their most impressive in raw power. It charges like a champ. My phone jumps from low battery panic to fully charged faster than I can finish a coffee. It even gives my laptop a solid boost when I am traveling, which is incredibly handy on long flights or when hunting for an outlet at the airport turns into a competitive sport. The capacity is huge, and the whole unit feels well built and premium, as most Anker products do. The convenience factor is top notch. Three ports make it easy to charge several devices at once without carrying a tangle of extra cords. The size hits a sweet spot, big enough to hold serious power but still slender enough to slide into a backpack pocket. It feels like a reliable travel companion that always comes through in a pinch. Now for the only real downside, that built in USB C cable. I was excited not to need a separate cord, but the moment I started using it, I realized it feels flimsy. It flexes too easily and does not inspire much confidence if you plan on using it daily. I find myself holding it gingerly like it is made out of angel hair pasta, hoping it survives another plug in. It is one of those small design trade offs that you do not notice until you actually put it to the test. For something marketed as travel ready, the cable should be built like the rest of the device, sturdy and road tough. Despite my grumbling about the cable, the overall performance wins me over. The power output is consistent, charging is fast, and I have yet to run out of battery even on long trips where everything else dies halfway through. The LED indicators are easy to read, and it holds its charge extremely well between uses. It is one of those products that proves how far portable chargers have come, just with one small but important weak spot. Overall, I would absolutely recommend this to anyone who wants a reliable, fast charging power bank for travel or everyday use. Just handle that built in cable with care and maybe keep a backup cord on hand, just in case it decides to give up early.

This sucker is perhaps the best thing I have ever purchased. It works for phones, laptops, earbuds... anything you can think of. It was a gift for one of my brothers and it is the gift that keeps on giving. It is an incredibly large battery that can charge many phones before it too needs to be charged. It has never overheated, is a manageable size, and is incredibly convenient when travelling. Very much recommend.

Buen power bank. No se calienta, carga rápido y tiene buena capacidad. Lógicamente, es pesado, pero es normal para tener esas prestaciones. Muy práctico que tenga su propio cable usb-c incorporado.

Excellent

Powerful and durable, very good quality

Melhor compra. Salvando meu dia, infelizmente depois de 1 ano a bateria do celular ja nao dura mais nem 12h continuas de uso intenso. O único detalhe do carregador, que de fato da carga completa rapidamente, e cumpre o que promete, é o peso do equipamento.

Really liked this power bank. I have been using it with my Samsung S24 Ultra, and it easily gives me more than two full charges. The charging speed and overall performance are very good. I mainly use it along with my Xiaomi Pad 6 tablet and phone, and this single setup is enough for me to comfortably manage for almost two days without worrying about power. Compact, easy to carry, and very reliable for daily use. I have been using it regularly since purchase and have not faced any issues so far. Definitely a good buy for travel and everyday use.
