    • Ultra portable charger and battery bank
Color: Phantom Black
I was interested in this model to avoid having to carry a separate charger and battery bank in a small bag. It seems to serve that purpose well, the folding plug prevents scratching other items and it can charge my devices both with and without a plug available. I wish it had a little more capacity, but I suppose a 45W charger and battery is already expensive, and making it any larger would make it a lot less portable. In looking at other reviews, it seems like there's some confusion about the capacity of the battery. The most useful metric in evaluating battery banks is Watt-hours (Wh). It claims to have an 18Wh capacity, and my testing suggests that they're probably telling the truth. Measuring using a fixed 10 Watt load, I was able to get around 15.8Wh out at both 5V and 9V outputs. Because of internal inefficiencies, devices generate heat when converting between different voltage levels. This is required because batteries don't output 5V or 9V, and that's what devices need to charge. Getting 15.8Wh out of a 18Wh battery would put the efficiency around 87% which sounds reasonable. The 5,000mAh number appears to be 18Wh at the nominal battery voltage of 3.6V. The 3,000mAh number appears to be 15Wh at 5V, suggesting what efficiency they were expecting. An iPhone 14 and 14 Pro has a slightly larger than 12Wh battery, so this bank should be able to fully charge such a device once if it was fully charged with a little to spare. As for some more technical details, when powered from both battery and wall power, it supports QC2.0, QC3.0, and USB PD 3.0. QC2 always supports 9V, QC3 always supports 3.6-9V. On battery power with a single device, the USB PD negotiations are limited to 19W with two fixed profiles of 5V@3A and [email protected]. When using two devices, it limits each port to 9W, QC2 and QC3 are disabled, and there is a single fixed PD profile of [email protected]. On wall power with a single device, it supports delivering up to 48W with fixed profiles of 5V@3A, 9V@3A, 15V@3A, and [email protected]. It also supports PPS at 5V-16V with 3A. Connecting a second device leaves the QC2 and QC3 options the same, but limits the PD profiles depending on if one of the devices is fast charge capable. If it's not (eg. AirPods), then the PD profiles are [email protected], [email protected], 15V@2A, [email protected], and PPS of 5-11V@3A. If it is, they're limited to a fixed [email protected] and [email protected]. ... show more

    • Works as expected, useful for multiple purposes
Color: Phantom Black
This charger is great in both forms: in-wall charger and power bank. When plugged into the wall, it delivers 45W, and when used as a power bank, it delivers 5000mAh (approximately 18W). I use as a wall charger daily to charge my iPhone 13 mini overnight, along with my MacBook Air or iPad Air when needed. As a power bank, I only use it for my iPhone or my iPad, and is capable of charging both simultaneously but I prefer not to. I never use the power bank to charge my MacBook Air. If I have access to an outlet, I will plug it. I only use the power when necessary. This being said, I do not recommend you use this to as a wall charger to charge other power banks. I attempted to charge my 65W Anker 537 power bank with this, and I think both power banks got confused as to which one was being charged, causing the Anker 521 to overheat to an alarming extent (user error). Speaking of overheating, it does heat up occasionally when plugged into the wall but not dangerously. Overall, I am very happy with this purchase, and satisfied with its usefulness every day. ... show more

    • Portable easy to carry
Color: Misty Blue
I got two for the family . Perfect for when going to be out a long time and can’t charge phone . It provides enough of a phone charge to your phone until you get home . I use as back up emergency . The charger itself is small , fits nicely in a small purse . It doesn’t takes long to charge up the backup battery and attaches nicely to the phone . Once you charge phone the backup battery goes dead so can only charge phone one time before you have to charge the charger again . ... show more

    • Great multifunctional device
How neat is it that it charges two devices as well as itself, and then functions as a portable battery? I'm happy with anything that downsizes my travel stuff. This device works just as it should. Just one drawback that isn't Anker's fault - the outlets in hotels/AirBnBs are often so worn that plugs fall out of them, and this one is heavy. So I take a small roll of tape to keep it in place. Extra stuff again, sigh... but at least the tape is also useful for removing lint from clothes. ... show more

    • Great Product
Color: Lilac Purple
Strong product. Have used this for a few years now. Great to throw in my bag for traveling. Has saved me a bunch of times. Slower charge when it’s in the wall, but on the go, still fire.

    • Duel purpose power bank.
The Anker 521 sure works really good and it came in handy when I needed it most when I went to Disney World during the past year and the 521 power bank also serves as a wall charger that not only charges your device such as your phone, the built in wall prongs also enables the power bank to be charged straight from the wall outlet without any cables at all. ... show more
