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.

Solid charger that fits everyone
Handy in many ways – I love the built in cables, easy to hand off to a friend without worrying about iPhone vs Android. Size is good, fits into many storage places, and it’ll recharge my tablet and phone several times between charges. Great value and happy to have it.

Durable easy to use and has built in cables!
Large 20,000 mAh battery — enough to charge most smartphones ~3–4+ times on a single charge. USB C and Lightning cable Bilt in. It’s little bit bulky, durable compared to previous models I used. Very simple to use only down side is you do need a wall plug but that usually the standard. Battery life is amazing.

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.

5/5 Stars…!!
After plenty of research and product reviews I settled on this Power Bank. The brand Anker was well known to be a good product from my experience.I purchased this unit because I’m on the road daily and it made sense for me. It does not dsiappoint! I charge my I-phone and 360 degree camera multiple times daily.I have tried other products. This one is superior.Very dependable, reliable and affordable.

1st DOA, 2nd Works Well!
Love Anker products. This is a bit bulkier than others, so not a jean pocket item (at least comfortably). 1st unit would not take a charge on arrival. Used the awesome Amazon return process (shipped a replacement immediately) and then used a local drop-off for the return. 2nd unit works well and rapid charges the phones as expected. For my S22 Ultra I expect 4 re-charges, and my iPhone Mini 8 re-charges. Love the dual built-in cables than handle both.Would recommend for others to purchase.

Perfect for Disney!
Took this to Disney with us and never ran out of a charge! It lasted so long! It’s about the size and weight of an iPhone so it was easy to carry around. It gets a little warm if you’ve got something plugged in for a long time but never to any concerning levels. This was exactly what we needed and we will never go back without one
Devaughn –
Excellent as a charger, great as a power bank
Fastest way to charge my iPhone. Even faster than the original charger and 20w brick. The fact that it’s a power bank is simply an added bonus. Can charge my phone at least around 3 times to full but for other phones (specifically iPhone 8, A series Samsung) it can charge them 5 times and leave 21% remaining in my experience.

Best one I’ve had in years! Super fast, very versatile!
Charges my old phone about 3.5-4 times before it dies .charges my new phone probably at least 5 times. If your phone is fast charging compatible, this thing is incredibly fast. Heck, it’s only 10W less than the block I plug into the wall, that’s how fast this thing can go! I also really love how it’s got the two charging cords (USB-C and Lightning) built in! I just wish the cords were longer, maybe something retractable? But that’s okay, because you can always plug in a USB C to USB C, or a USB A (regular USB) to USB C cord into this! (Probably fastest if you use a C to C).So this thing is wildly versatile. The only downside is it’s quite thick, however somehow it’s also lighter than my previous power bank that didn’t pack nearly as much charge or wattage. It’s worth it, just make sure you have a long cord or a big pocket!

Product works great and holds charge for months. Ended up buying a second due to it exceeding expectations.
Amazon Customer –
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.

Awesome battery bank. I got this for travelling and work and it’s never let me down. The built in cables are convenient and the charging is really fast, I can fully charge my laptop with it, and I can charge my personal and work phone at the same time.It takes a while to recharge the battery bank with a standard charger but that’s because it has so much capacity.Best value battery bank on the market IMO, and the advertised capacity and output is true (which is rare for battery banks)
