Awesome powerbank. Another great product by Anker.

I wish that could have more usb ports but overall its a ggood product

I bought this power core to replace my older Anker that walked off one day at work. As expected, its performance is TOP notch. I took this one on a trip and was able to charge my work phone (iphone) using the small USB-C while using the larger USB As to charge my tablet and phone. These do have a longer recharge time if you drain them substantially, but nothing that plugging it in overnight can't fix. I would never have needed to buy a new one (my old one was going strong after four years and many overseas vacations) if my old one wasn't stolen. Couldn't recommend this enough.

Great charger never had any issues with this charge so make sure you get it.

It’s 2023 and we’ve come a long way since the first portable battery packs. However, I feel that the recharging on this takes way too long, especially using a 45w plug. The output to charge your devices is ok, I would imagine we are advanced enough to have at least fast charging on these battery packs, sadly it only works when the battery is at full charge.

Over the years, I have bought many battery packs for charging up various devices. I have one that is 1000mAh that is really tiny and has barely enough power to charge a phone for a few minutes. At the time it came out, it was good enough. By today's standard, it's nothing. I have one that I bought a few months ago that is 30,000 mAh that I planned to use on my Oculus Quest 2 by printing a 3D mount to hold it on the back of my head. When I received it, I couldn't believe how heavy it was. It weighed 1.5 pounds. If I wore that on my head, I would have a stiff neck in no time. I needed something that weighed less. I decided to go with this Anker - PowerCore III Sense 20K. It's 10,000 mAh less than the other one but it only weighs 12.5 ounces and 1/3 the thickness. One thing about Anker products, and I have owned many, is they are made incredibly well. They make their products look great and you can feel the quality when you hold them. This battery pack has a fabric top and a matte finish on the bottom that feels comfortable in your hand. There is a button embedded in the cover that you press to see how much power the battery has by looking at the 4 tiny LEDs on the button. 4 lit LEDs means the battery is full and 1 means you should charge it up soon. On the side of the battery pack, there are 2 USB-A jacks and one USB-C jack. The USB-C jack is used for charging the battery with the included USB-C to USB-C cable. The USB-C jack can also be used to connect to your device whether it is an Android phone or another device like the Oculus Quest 2. If you need to charge an iPhone or a device with a standard USB-A jack, you will need to provide your own cable. Unfortunately, Anker doesn't provide a charger in the box since they also sell chargers of various styles with multiple jacks. According to the box, this battery pack provides roughly 92 hours of power which would come in pretty handy in the event of a blackout or on a long camping trip. It also says that this battery pack can charge most modern phones 3X faster - charging phones up to 50% in 30 minutes as it supplies 20W of power using the USB-C port. Included in the package is also a mesh drawstring case for protecting the battery from scratches when you throw it in your bag. The PowerCore III Sense 20K comes with an 18-month warranty just in case but being that it's from Anker, I doubt very much you will ever need it.

Pretty awesome! Would definitely recommend. The battery life could be a little better but still worth buying!

great battery charger, really like the texture choice anker decided to use,

Holds a decent charge but honestly for how long it takes to recharge it really isn’t helpful for long weekend events

Took it to Disney so i wouldn't run out of power. Worked all day!

Big upgrade from my last Portable battery pack. I like that I can charge 3 device at the same time. The type c port charges my S22+ fast.

Reliable and but sometimes I feel like it takes forever to charge up.

This lasts way more than needed. You don’t have to constantly charge the battery pack especially if you haven’t used it in awhile.

Charges my phone multiple time, could be faster though

Product performs well and I’m happy with the build quality.

Good reliable portable power bank and retains charge longer

It takes longer than normal to charge compared to others I’ve purchased in the past.

Pretty product, takes a little long to charge, but it’s reasonable for the amount of mAh

Works for a portable charger, about average performance.

Good; however you need a USB to C connection to charge device that didn't come with device.
