Great travel portable battery charger.
Portable and durable battery charger. It's a little bigger than a Galaxy Ultra. Lots of power, easy to use, and stays cool. Nice black stealth color and sleek design. Long battery life to recharge devices. Fast charging. Great value for my money.

Anker Portable Charger
I found this charger by trying to look for the more expensive option since it’s a charger and didn’t want to cheap out. I am happy I went that route!! I’ve been amazed with the quality of it, it’s heavy and not cheap which is good because that means it will be resistant to drops and stuff. It is about as big as my phone. It is simple to use and works amazing. The battery life on it is great and I like how it doesn’t use battery if you have nothing on the other end of it so I can leave my usb in and as long as it’s not plugged into anything it won’t waste battery I think that is good for keeping my usb with it. My only concern at first is that my usb wouldn’t fit in all the way but I realized it was just right because it was new and I pushed it in harder and it fit. Which is a good thing because that means your usb will not fall out and it will stay in there and not keep falling out and being annoying. It uses usb 3 and it says “IQ” technology on it and it must be way better than a normal charger because this thing charges fast and has amazing battery life at the same time. I also like that it has 2 inputs (how you charge the battery itself) it has usb micro and usb C inputs which is cool. My only complaint is that it doesn’t have usb outputs espcially since the newer iPhones come with that type of charger. I’m so happy I picked the Anker charger and didn’t cheap out!!! Great product!!!

Great Product
Very durable, high quality product. I use to power camera and tablet in a race car. Zip tie them to the cage, plug in and go. Likely would make 24 hours, we change them just in case. Possible to lock power on with a double click. Light for the amount of power, easy to charge. Multiple outlets are convenient.

HUGE battery capacity
I've bought 2 of these power banks now: 1 as a gift and the other for myself. This is the perfect power bank for traveling since it is able to charge my phone multiple times before it needs to be charged back up. It's a bit on the heavy side, but I'm also able to walk around with it in my back pocket as needed if I'm charging my phone on the move. It does not have quick charge, so my phone won't get back to 100% as fast as my wall charger, but it's nice to not have to be tethered to a wall as well. I have tried using this power bank to charge up my Macbook Pro and didn't have great success charging and using it at the same time. It might do just fine if the computer is sleeping, and will need to test that at some point. As someone who doesn't do a ton of traveling, I still use this power bank quite often even around the house. Moving my phone from room to room with the power bank is much more convenient than having to remain close to a wall outlet. It's really an impressive battery for its size and I would definitely recommend this for anyone looking to keep multiple devices charged or who does a lot of traveling.

Good battery with 2-4 years of useful life.
Mine went 3 years 6 months before it bulged/died. Thermal runaway. I see people on here giving 1 star for similar situations and to be blunt, that is not fair to the company. The useful life of these batteries is 2-4 years when handled properly. My only complaint is the case was too smooth. Anker makes more rugged options with a metal case, so probably leaning towards that for my replacement.

Great portable charger
Great portable charger. Quickly Charges devices, has a great battery life for its size, and it has great resistance against the elements ( snow & rain ). I’ve had it for almost 2 years now and it still works the same as the first time.

A bit slow when charging devices, but very sturdy and reliable.
It's a bit hard for me to review the product because I stupidly bought it used. Don't do what I did, you'll end up with a significantly lower capacity power bank. Mine only holds about 13,900 mAh when it should hold 18,000 to 20,000. Entirely my fault. But it works very well. I feel like it takes ~6 hours to charge with a 20 watt USB charger (all power banks take a long time to charge). I've run two phones off it simultaneously and it kept them running just fine. It's physically sturdy and it has never gotten even warm when charging it or discharging from it. My only complaint is it doesn't charge devices very quickly. For both my phone (Google Pixel 4a) and tablet (Amazon Fire HD 10) this power bank can only keep up with power usage of the devices when they are on and active (e.g. you're actively using them while charging). Neither device battery gains power in that situation, but they don't lose it either. When your devices are idle, it's pretty decent. Closer to wireless charging speed (this doesn't have wireless charging capability, that's just a comparison). If you want a power bank that charges your device as fast as your wall charger does, look elsewhere. This isn't that expensive of a power bank. If a somewhat slower charge time doesn't bother you then this is a decent power bank for the money.

I bought this Anker Powerbank 20,000mah few days back. I am fully satisfied with the product quality and it is doing it's job perfectly. Charged this powerbank overnight and it is charging my iPhone 14 Pro Max at 15W i.e it is working as fast charger. Charged my phone in less than 1.5hrs. I will recommend everyone to buy it who are looking for a powerful powerbank from a trusted brand.

Tengo esta otra powerbank más grande que cuando hago viajes largos o me voy fuera de casa todo el día me la llevo siempre. Carga mi móvil completo más o menos 3 veces, tengo un s21 plus. Viene con su cable y tarda mucho en cargar pero porque tiene muchos miliamperios. Una de la cosas que más valoro es la calidad que tiene.

Anker si è dimostrata ancora una volta una tra le migliori marche in assoluto nella produzione di powerbank. Che dire, 20000 mah sembrano essere infiniti, non finiscono mai, la carica è rapida grazie all'ingegnosa tecnologia Power IQ sviluppata interamente da Anker. Non devo preoccuparmi in quale porta inserire il cavo per ricaricare il mio telefono perchè è il powerbank stesso a generarmi la corrente ottimale. É solido, compatto e sinceramente a mio parere non pesa poi così tanto. Sono uno studente universitario, giro sempre con lo zaino e a volte mi dimentico di averlo dentro. Mi sento di raccomandare a tutti di rispettare il voltaggio per caricare il powerbank, non capisco le recensioni negative sinceramente. Bisogna caricarlo correttamente e non prendere un qualsiasi alimentatore credendo che non faccia la differenza. Lo rovinate e poi vi autoconvincete che la colpa sia dell'apparecchio e non la vostra. BUON SENSO. Il powerbank è provvisto di: -cavo di ricarica -istruzioni -custodia (molto comoda) PRO: -potenza di ricarica: 20000mah infiniti -velocità di ricarica: ricarica il mio iphone 6 e 7 molto più velocemente dell'alimentatore della apple -stile -versatile -comodo: grande quanto uno smartphone -solido -rapporto qualità-prezzo ottimale CONTRO: Per ora nessuno In conclusione mi sento di consigliarlo a tutti, è ufficialmente il powerbank migliore che abbia mai avuto ad un prezzo accessibilissimo. Compatibile con tutti i dispositivi e con una ricarica perfetta, personalizzata ed estremamente sicura, cosa che manca a parecchi powerbank. Change my mind.
