Great!
I bought this product before our trip to Japan because I figured we would be using our phones a lot and this product did not disappoint. This was probably one of my best purchases for the trip. With both a lighting cable and a USB C and a traditional USB port we used it to charge my phone, my wife’s phone and even little battery powered fans that people carry around. In Japan we used our phones for EVERYTHING (subway tickets, maps, translators) and this kept them charged up all day with no problem.

Works Great! Holds A Charge for a Long Time! Great for Travel!
This is AMAZING! I got it for a trip and I've taken it on several since and it has not let me down. It has cords for my android and my partner's iphone which has come in clutch. On one charge, it was able to bring both mine and my partner's phones up to 100% no problem. I've taken it to theme parks, on planes, through long days, it even got a little wet briefly and it has kept going. It does get slightly warm when charging itself/phones but that's my only "concern".

Good and sturdy
Worked really well. Charging felt moderate not as fast as I would have hoped but did the job on my older Samsung phone and ipad with plenty to spare. The built in cords were fantastic and sturdy. Having a USB-c and Lightning was great for someone with different devices. Also good for helping others charge their phones. Good size, similar to a phone but thicker.

It’s good
I’ve had this for 6 months now. I enjoy it and use it daily. Holds a charge well and I can get about 3 full charges off of it. Takes about 2 hours (maybe) to fully recharge. I don’t know the exact amount of time but it’s not very bad! Only complaint is that the cables are a little too short for my personally liking. It’s hard to hold the phone and the charger together- the charger itself is rather bulky and has some weight to it so it becomes this huge heavy thing when connected. It’s also hard to fit both the phone (IPhone 11s) and the charger in your pants pocket while charging. I feel like if the cables were a bit longer it could help with juggling the two items when connected. It’s hard to explain but it’s like your phone is on a very short leash and attached to a big bulky weight. I bought this originally for travel/theme parks and while it’s a good charger, it’s just not the best to take on the go like that. The charger and phone really need to be laying flat and still during charging to prevent cable stress. I try to be careful with the cables but I have accidentally dropped the charger while it was attached to my phone before. The cables kept it connected which honestly worries me. It’s like the cables are one accident away from being jerked out completely and I’m just not sure how great this charger will be once the cables get damaged. It does have other ports you could use but that almost defeats the point of this particular version of portable chargers. As stated above though, I’ve had this going on 6 months and so far it’s still ok and the cables are fine. I just have to really make a mental note to stay aware while using it so I can avoid cable damage. If it broke tomorrow I might reorder just for the charging power. I would compare some other Anker batteries first though! And I wouldn’t reorder to use solely for active travel, I would look for better option.

Worth the price
Very heavy duty and charges fast! I thought I could put my phone on it to charge but I can’t but other that it was compatible with my phones, the cord length was perfect (I can use it as it’s charging) and it just gets warm not too hot when charging.

Holds its charge so it's ready to use when you need it.
I love this sleek power bank! I charged it more than 2 weeks ago and it still has a full charge on it. Others I've tried have not held their FULL charge this long. I used it this morning to power a portable fan, for at least an hour, worked great! I'm getting another one to keep in my emergency kit.

I expected a working power bank not a debugging project
I ordered three of these. The first two I opened were stuck at 25% charge and would not take charge. After much debugging and research I did a "reset" of both units by plugging the out cable into the in port for 15 seconds. This allowed #1 to take charge and I even successfully test charged an iPhone off it. #2 was just reset again and I'm trying charge it once more (it's now stuck on 27%). If I can get #2 to work I will open the third one and see what's what. I will update this post once I have more results. One star because I expected a working power bank, not a research debugging project.

A literal lifesaver? Maybe.
I can’t say for sure that this power bank saved my life, but it definitely enabled me to get out of a very tight spot. I bought this to take on a trip to Iceland, and I’m very glad I did. I was out one night looking at the northern lights, and managed to lose my sense of direction. I was alone (stupid, but there were reasons) and was in an area that I hadn’t explored in daylight (also stupid). It was pitch black and, even though I was dressed for it, I was getting cold. The ground was rough and hazardous. I had my phone to use as a flashlight, but batteries die fast when it’s cold, and mine was getting low. The only smart thing I did that night was to bring this power bank with me. It kept my phone/flashlight going long enough for me to find my way back to familiar ground. (In case anyone is wondering, I couldn’t get a cell signal, so I couldn’t call for help.). Would I have frozen to death without this? Probably not, but it saved me a very uncomfortable night and possibly an injury from falling over something. So five stars to this power bank! It’s pretty heavy (at least the 20,000 one is), so I usually carry a smaller one for daily use at home, but when you need it, you need it! Works just like it should, provides a lot of power, and love the attached cables.

Handy built in cables and brilliant capacity- would easily run my devices for a few days
Brilliant, charges iPad and phone multiple times and I love the built in cables. It is quite heavy so would only use for long travel or full on days out where my devices run out of juice quickly due to taking lots of photos, streaming etc. I have a smaller capacity, more handbag friendly one for smaller outings as although it easily fits in my handbag it's just more weight than I want for daily use.

Carga rápida y súper práctica para viajes y uso diario
Ya había tenido la versión solo con cable Tipo C, pero se me cayó del bolsillo mientras iba en la moto 😅. Me gustó tanto cómo funcionaba que decidí comprar esta versión con Tipo C y Lightning integrados. Me encanta que es 100% compatible con mi iPhone y mi OnePlus. Carga realmente rápido ambos teléfonos y es muy práctica porque ya trae los cables integrados, así no tienes que cargar extras. El único punto débil que le encuentro es que la power bank tarda bastante en recargarse por completo. Fuera de eso, el rendimiento es excelente: fácilmente puedes cargar tu teléfono 2 o 3 veces con sus 20,000 mAh. La he llevado en viajes y salidas de varios días y nunca me ha dejado tirado. Totalmente recomendada si buscas buena capacidad y carga rápida en un solo dispositivo.

Great product
Product works great and holds charge for months. Ended up buying a second due to it exceeding expectations.

Another great Anker product!
Bought this to replace a previous Anker charger that had served me well. Liked the idea it was smaller to carry around and had the in-built USB-C and lightning charging connectors with it too, meaning I didn't need to carry numerous charging cables with me. This was the real selling point for me (plus it's in another colour other than black!) Took it on a test drive on a day trip to Belfast and used it to top up my phone charge. Was easy to use and feels premium. It's a fair weight for a 20,000mAH charger and not something you'd want to carry in your coat pocket all day, but it's the sort of thing you'd slip into a day bag or rucksack, forget about and go about your day easily. I love the charged percentage display. If you connect it to a USB-C plug charger, it'll take next to no time to charge, however I haven't had to do this from near-empty yet. Another great Anker product in my opinion - thoroughly recommend.

Great power bank!
My go to brand for electronics. This power bank even went for a bit of a swim and still works well! Size and weight is a bit bulky but love the speed it charges devices. Love that I don’t have to carry cords for old Apple and android products. I buy anker plugs, cords and always look for this brand for electronics.
