Plenty of Portable Power, A bit larger than expected.
I recently was looking for a replacement battery pack, as my old Anker 10,000mAh battery pack had begun to wear out after years of use.Furthermore, I upgraded to the iPhone 15 Pro Max & I needed more than 10,000mAh for on-the-go. Now, I always carry extra cables with me. However, the idea of an attached cord was certainly different.I decided to purchase the battery pack, in Black. It was a hard choice between the Black, White, and Purple. I will warn you: The black shows every smudge, scuff, lint, spec of dust, etc. It is sharp, but be aware it will show every imperfection.The battery pack was without a doubt larger and heavier than anticipated. My old Anker pack was much lighter and not as bulky. I am sure the additional 10,000mAh does make things a bit thicker and a bit heavier.I will primarily keep this battery pack charged up and in my purse for on-the-go type situations. The pack took a few hours to charge, using the built-in USB C cable and an Anker NANO power brick.The battery has a small display built into it to display the charging indicators and battery level. The battery also offers a “trickle charge” mode for things like AirPods.You’ll also find a convenient “stand” that pops out of the battery pack. They certainly thought of all the little details.I’m not sure how the battery would hold up to people carrying/handling it like a wristlet. I would imagine the cord would eventually fail due to repeat stress/force.The battery pack can charge three devices, simultaneously. You have the included USB C cable, a standard USB-A connection, and a USB C connection. I plan to use a separate cable and plug into the USB C port.We will have to see how it performs and holds up. I look forward to having an additional 10,000mAh of power at my disposal. I am a big fan of Anker products and have yet to be disappointed.However, it is certainly a bit more bulky than I had expected. I am hoping the performance will make it worth the bit of extra weight in my purse!

I took this with me on a trip to Buenos aires and it was such a life saver. This is a must for walking around the city since you use so much battery on gps walking. Fits easily in a small backpack. It charges reasonably fast in my opinion considering the battery size. I love the USB-C port and cable built in. Charged my phone super fast. The screen is slick as well. Perfect form factor. Great product on my trip.

This is the best powerbank I have ever owned. So many pros: It supports two-way quick charging which means it charges your devices at max speed and also rechanges itself with rapid charging (very rare) the universal USB-C plug can be used for input and output and doubles as a lanyard. No need to carry an extra cable. It can also switch mode to trickle charge smaller devices. My favorite feature is the integrated phone stand that charges while watching media. It also has a clear digital display. Only down side for some is that it may be too bulky. I can fit the phone and charger in a loose-fitting pocket. With this battery, you could go off-grid with your phone and ear pods for 2-3 days with no worries.

I give this the Gadget of the Year award for delivering features to cover almost every need.

This is a pretty compact battery for the size and the handle/ USB c charge cable is a great design that makes it easier to carry around.

It takes a while to charge. That's the only negative. I'll plug it in and it seems like many hours to go from 51% to 52%... But once it starts charging it fills to 100 and I get a lot of charges before I need to recharge the battery. I would buy this again and plan to for gifts in the future

I like that the USB-C cable is included for charging the power bank, and the same cable works for my phone/USB-C device! It’s heavy, but it holds a lot of power. After using GPS/AllTrails on his iPhone 15 for 4-5 hours to navigate us up a mountain, my boyfriend’s phone’s battery was low. This helped re-charge his phone quickly to get us back down the mountain. I also love the lavender color; it’s so cute! Definitely worth the money and the weight in my bag!

Wanted something portable to recharge my phone because I find myself often on low battery or none before the end of the day. It does take several hours to fully charge, but it quickly recharged my phone. Gave to my friend when they lost power for a few days. She was able to use to recharge her phone over the next 4 days.
I recharged a week ago and it still has 100% available. Great tool. A little heavier than what I wanted but works great.

This charger ensures that when we are traveling, both our iPhone 14 Pro Max stay fully charged for the whole day. It can be used for two full days before needing to be charged for use again. Building USB-C is great for newer iPhones (15 Pro max or newer) but for iPhone 14 or older still need to bring a Lightning cable.

If you have an iPhone 15 pro max, don’t hesitate.

I needed to find a replacement battery pack that no longer worked once I upgraded my iPhone. A friend recommended Ankers and this one was in my budget. It charged my iPhone right out of the box. This is going to be very reliable on upcoming trips. The attached usb-c cable is perfect so you don’t have to carry extra cables. It is heavy but small enough to carry in a fanny pack. Recharging does take a long time but it’s not a problem for me since I do it overnight.

5.0 out of 5 stars Pila bastante práctica
Reviewed in Mexico on July 4, 2024
Color: BlackVerified Purchase
Es una pila muy practica ya que trae un cable usb C integrado, que sirve para cargar cualquier celular que soporte 22.5W y también por ese mismo cable recargar la bateria, soporta 20W de Input, además de otro puerto usb C que también es de entrada/salida, mismos 22.5W.
El otro puerto usb A también entrega 22.5W y ese puerto solo es de salida, o sea que solo carga otro dispositivo pero no admite recargar la pila.

Recargué la pila de una Macbook Air M1 del 10% al 99% en tan solo 1.2 hrs, fue bastante rápido, no se calentó la pila ni tampoco la compu entonces es una buena opción por si no traes el cargador de la compu, cel, tablet, etc.

No la he probado cargando 3 dispositivos al mismo tiempo pero supongo que la potencia de cada puerto podría disminuir (o tal vez no, pero no dice nada al respecto en el manual de usuario)

Ademas tiene un modo de carga lenta que lo activas al dar 2 clicks en el botón de encendido y en la pantalla te muestra con un puntito verde que está activa la carga lenta, eso sirve para algunas bocinas, audífonos y cargadores inalámbricos que no soportan mas de 10W de carga

Muy buena compra, la recomiendo, solo tengan en cuenta que es algo pesada la pila, alrededor de unos 300-350gr ya que son 20,000mAh, para mi no es inconveniente el peso

5.0 out of 5 stars A real power tank!!!!!!!!
Reviewed in Canada on March 24, 2024
Color: BlackVerified Purchase
A power bank's main purpose (perhaps the only purpose) is to charge other devices when regular power is not available. And this Anker power bank really performs. To test it, I first drained my iPhone 15 Pro to only 1% of charge. I then connected my phone to the power bank using a C to C cable. It charged my phone to 32% in 15 minutes, to 50% in 25 minutes, to 70% in 40 minutes. Then the charging rate slowed down. It took 85 minutes to charge my phone a 100%. My phone and the power bank were always cool to the touch. Not even a little temperature rise on both devices. At the end, the power bank was showing 76% of charge.
I will drain my phone again and again to see how many times I can charge it until the power bank runs dry. I will post another review in two weeks. So far, I am extremely satisfied ( and impressed) with this Anker power bank. Some reviewers complain that this power bank recharges slowly. So what???? Are you looking for a power bank that recharges quickly but craps out and runs dry just as quickly, or are you looking for a power bank that really performs on the field? Granted, I recharged this power bank for the first time and took a little over 4 hours to recharge. But it really packs a lot of power. Recharging this power bank is a no brainer. Recharge it over night or whenever there is power available.
As I said at the beginning, power banks are meant to charge other devices. And this one, is the champion of them all.

I am now reviewing this power bank for the second time.
And I am really impressed. It charged my new iPhone 15 Pro from 1% to 100% charge four times. That's right, four times ( completely full) and the power bank still had 2% left over.
And every time, it charged my phone really quick.
Don't look further, this is an amazing power bank.
