Power Bank, 20,000mAh Travel Essential Portable Charger with Built-in USB-C Cable, 3-Port 87W Max Fast Charging Battery Pack, for MacBook, iPhone 16/15 Series, Samsung, Switch, and More

This thing has been my buddy for when I travel. I regret if I don’t bring it. If it’s just for my phone, it will last me multiple days until it needs to be recharged. I’ve been able to help myself and my friends out whenever we have a low battery, and with how fast it charges, you rarely have to wait long. Even in bed, I won’t have to hold onto it for long before it gets me at a stable battery level to doomscroll into the night. Only cons are the weight and size, but it’s reliable and does its job perfectly otherwise. Just small enough to fit into a pocket, but it’s bulky and heavy. Maybe doable behind an inner hoodie pocket, but most easily accessible and hidden from a backpack or handheld bag.

This power bank is amazing! It was an absolute life saver when I traveled internationally this past summer! I was not often near a plug outlet, and this saved my phone! The built in USB-C cable also meant one less cable I had to keep track of. The USB-C cable can charge your own device, and you can also plug into a USB-C port to charge the power bank itself.

Outstanding product! I like the minimalist U.I. - just one button to push to turn the screen on, & a double click to put it in/out of the trickle charge mode (which you'd never need to do if you just use the USB-C port/cord to charge lower power devices like headphones). It charges my phones as fast as any high quality wall charger, & can charge my phone a solid 3 times before it's needing a recharge itself! I like that there's a built in cord, & especially LOVE that the cord can be tucked securely into the side of the power bank! So many other power banks use their built in cords as a "lanyard" which I really just don't think is a wise idea. Not only is it more stress carrying it around by that cable, but I also don't want a idiotic lanyard hanging off the side & getting snagged on things when taking it in/out of cases, drawers, bags, etc... When I came across this model, it's neatly tucked away cable is what sold me! Couldn't ask for a more perfect power bank! This might not be for you if you want slim & light for pocket carrying as it's a bit heavy. But if you aren't planning to carry this in your pants pocket, the weight it not an issue at all.

I purchased the Anker Power Bank 20,000mAh as a travel backup, and it’s been a dependable option for larger charging needs. It is on the heavier side, but still compact enough to take on an airplane without any issues. It also holds a charge extremely well when not in use, so it’s always ready to go. Having the cord attached is a big plus—one less thing to pack or lose. A solid choice for travel, long days out, or anyone who wants reliable extra power on hand.

I have been a proud owner of my Anker portable charger for nine months. It mainly lives in my EDC bag, but has also gotten used in the home when my youngest child is using her phone but not near an electrical outlet and her battery is low. It came in handy for my teen who needed to have a backup charging source with her for computer-based standardized testing. I feel good knowing that if there's a power outage, I have a reliable charger for my Android phone, MacBook, and Bose headphones (when in trickle charge mode for low current devices). And, when we go out of town...this charger ALWAYS tags along. I love the built-in charging cable—that's a gold feature in itself. I have a few other chargers, but this is my primary for that reason. If something were to happen to it, I would purchase it again. It recharges quickly with my 45W charging block using either the built-in cable or a separate USB-C cable. I am considering buying both of my children one for Christmas this year to replace their Anker chargers (that don't have a built-in cable nor provide as many charges). What's not to love? It's compatible with my devices, provides me with multiple charges, it's reliable, and I love the Anker quality. Update (2/12/26): I bought the violet Anker for one of my daughters for Christmas (see photo). I also purchased a case for mine recently (purchased on Amazon and reviewed separately; it offers nice protection, but it's hard to catch in stock). https://www.amazon.com/dp/B0DGFRD1JB?ref=ppx_yo2ov_dt_b_fed_asin_title

Great charger/power bank. Used for several brands of phones, portable games, flashlights, etc. Super fast charging my Samsung Galaxy s23 and s24 ultra without issue. Huge capacity. I like having the cord attached. Nothing to have to remember when going out. Just grab n go. It's a tad heavy and bigger than some other 20,000mah power banks so only 4 stars from me. Highly recommend if you don't care about size.

I love this, have it by my bedside every night to help charge my phone as the cable is too small from the outlet. The built in cable is a cool feature and it charges my MacBook Pro too. Only issue is that it doesn’t charge crazy fast and drains the battery drastically when charging MacBook. Regardless it does charge the power bank very fast using my 87 watt Apple charger which is nice

This is the best portable charger I have ever owned. I bought this one mainly for charging my Switch 2 on the go as the battery life is not great on that one. This works perfectly for keeping it charged and able to play whenever I want. We also took it to Florida on vacation with us. It is a bit heavier than my previous chargers, so my wife made me carry it. But when the phones need a quick charge, this did the trick. Very happy with this purchase and would highly recommend for anyone looking for a charger for new devices. Especially, the Switch 2!!

Excellent

I've owned a lot of power banks over the years, but they all had the same problem: they were useless if I forgot to bring the right cable. This Anker 20,000mAh power bank completely solves that. The built-in USB-C cable is an absolute game-changer. It tucks away neatly into the side of the unit, and it means I can just grab the power bank and go, knowing I have everything I need to charge my phone. The capacity is massive. 20,000mAh is enough to charge my phone (a Samsung Galaxy) at least three to four times from empty, with some juice still left over. It's perfect for a long weekend away, a festival, or just for those busy days when I'm away from a wall socket for a long time. It also charges my tablet and headphones without any issues. Beyond the built-in cable, it's also got a standard USB-C port (which works as both an input to charge the power bank and an output) and a USB-A port, so you still have the flexibility to charge older devices or help out a friend who has a different type of phone. The charging speed from the built-in cable is great, supporting fast charging for my phone. In terms of design, it's about what you'd expect for a high-capacity bank – it's got some heft to it, but it's slim enough to slide into a backpack or a large coat pocket without being too obtrusive. There's also a handy little button on the side with a circular display that shows you the exact percentage of battery remaining, which is much better than the vague four-dot systems on older models. Verdict: This is pretty much the perfect power bank for anyone with a modern USB-C phone. The combination of huge capacity, multiple ports, and the sheer convenience of the integrated cable makes it a top-tier product. It’s reliable, well-built, and has replaced all my other portable chargers.

I really liked the 87W, I can charge two phones or a MacBook quickly and without any problems. I used to use 30W and only now I realized how terrible it was. And the built-in cable is very convenient. I am no longer afraid of forgetting the cable and being left without a charger.

Totalmente acima das expectativas. Carrega um IPhone 16 e só usa 25% da carga dela. Não esquenta muito (o dispositivo sendo carregado geralmente esquenta bem mais que a bateria em si). Só é bem pesada, mas é esperado de um produto com 20kmAh. Muito bem feito, acabamento bonito e elegante. Excelente compra!

Très bonne qualité, une marque reconnue. Charge rapide pour mon poco, et une bonne capacité. Très pratique le petit câble
