Is it normal for the power bank to recharge slowly?
The 20,000mAh power bank typically recharges in 5 hours and 12 minutes. We recommend using an original 20W or higher PD charger for optimal charging speed.
Is it normal for the power bank to get slightly warm during use?
Yes, it is normal. The product meets safety standards with a maximum temperature rise of 118°F (48℃).
How can I estimate the number of charges for my device?
To estimate charges, use this formula: (Power Bank Capacity × 0.7) ÷ Device Battery Capacity. For example, an iPhone 15 Pro with 3,274mAh can receive about 4.27 charges from a 20,000mAh power bank (calculated as (20,000mAh × 0.7) ÷ 3,274mAh).
Why does the power bank sometimes not charge when multiple devices are connected simultaneously?
This power bank supports multi-port output with a maximum of 5V/3A, 15W. When using the built-in cable with either the USB-A or USB-C port, the output voltage is 5V. Please confirm that your devices support 5V charging.

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.

Awesome and reliable
Love this product. Anker has been a very trusted brand for me. This has helped because not all my apple devices are C cable. I like that I can carry it around fully charge for days and still have power when I needed for emergencies. I hope one day they can make less bulky.

great for travel
The Anker Zolo Power Bank is an excellent choice for travel due to its built-in USB-C and Lightning cables, which eliminate the need for extra cords and streamline packing. I took this charger on an international trip and has great build quality and features. You are able to charge a phone 4 times. For the price, its hard to beat due to its build quality, capacity and built in cords.

Fast re-charging, convenient cables.
Bought for an over-seas trip. Worked great to charge an iphone SE 2x and it still had some power left over. It recharges quickly and the small screen lets you know exactly how much charge is left. The included cords are super helpful to charge devices without needing to carry extra cords, and they work as a carrying strap too. It is a about double the thickness of the cell phone, but fits easily in the small pockets of backpacks and bags, but probably wouldn’t be comfortable in a back pocket along with a phone.

Love the attached cords.
My work just switched to USB-C iPads and I have an older iPhone that still uses lightning. I love that both cords are included permanently attached to this device. It works well and charges your devices fast.It is a little heavier than I expected and it takes a while to charge, but it does what I needed it to do and I don’t have to keep track of charging cables anymore. I also like the battery level percentage is on the screen and available at the push of a button.This may be a little bigger than expected and does not fit well in a pocket if that is important to you.

Fantastic charger & well worth the money
Love it!I use this for work and the 20,000mah battery means I only need to charge it once per week; I’m using iPhone 16 pro. It only gets warm when I have the phone and battery stacked.Lightning and usb-c connectors with strong braided cord/strap; charges very fast over usb-c.Worth the money!

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.

This power bank has been a lifesaver during travel and long days out. It charges my phone quickly and holds enough power for multiple charges. Compact, lightweight, and solid build quality — definitely worth it!
