AnkerPortable Charger 2-Pack, 20000mAh Battery with 20W USB-C Output, Supports Power Delivery, 525 Power Bank (PowerCore Essential 20K PD) for iPhone 15/14 Series, Samsung, iPad Pro, and More

Plenty of power to recharge an ipad or iphone. Enough power to substantially add battery life to a laptop.The power bank is small for what it does and I think the size is quite nice, but others may feel it’s a little too heavy. I do not think most people would be disappointed at the size considering this is 20,000mAh.It holds its charge when not being used for at least a week or two (I have not had it long enough to test it for longer periods yet.)It does not run hot.The only relative negative is that it takes about 4.5 hours to recharge from empty. This is not too long, but may require some planning depending on the situation. Other power banks are out that can recharge faster, but they are heavier, more expensive, and may require to be plugged into a high powered charger in order to obtain the faster charge.This power bank is inexpensive for what you get. One very nice thing is that this charges through C to C, C to lightening, and not just USB-A.I do think the shipping took a couple of extra days versus 1 day, but this was disclosed when I bought it.It did arrive on the day promised.I highly recommend this power bank for anyone that needs more than a daily phone charge. Great for traveling, long airplane flights.For a daily phone charge get the Anker with 10,000mAh and C to C charging (in and out).

Functions well, perfect size. I have 2 of these and they recharge quickly, charge devices fast, and have a very reasonable use capacity.

I’ve never seen this power bank run out, ever. This has gotten through multiple charges of multiple simultaneous devices at music festivals and such, and just keeps going. Even after months of non-use when I totally expect it to have died, it stays fully charged and ready to go. Due to its slim size it fits easily in a backpack or fanny pack, and while it’s a bit chunky for a pants pocket it’ll fit there in a pinch too. It also feels very durable and well-made.

Works well. Charges up slower that it charges other devices. Use at least a 30 watt charger (USB-C to USB-C) to recharge it. A 5 watt charger will take overnight to charge it up.It is a little large though and can not be used on air flights and may not even be allowed to fly on some airlines as baggage, you will need to check if that is your purpose.

This was my first experience with Power Delivery (PD) and I'm very impressed. It's capable of charging all my devices. It charges my phone (10W), Nintendo Switch (18W), and laptop (65W). Note that the laptop slow charges since this battery bank can't put out 65W, but it's still fairly quick. With PD, I no longer have to carry around two or three wall chargers, cables or battery banks when I travel. I don't even need my original laptop charger anymore which saves me a ton on packing space (I bought a 65W PD wall charger to go with the battery bank). Simply put, PD is awesome and it's definitely the future.The size of the bank is somewhat large. Similar dimensions to a large cellphone with a thick case. I don't think it's too large though. It fits in my standard Nintendo Switch carrying case without putting pressure on the joysticks or screen.The battery life is very impressive. Off of a full charge, I used it to charge my laptop from 65% to 100%, my Nintendo Switch from 27% to 100% and my phone from 19% to 100%. It's indicating that it still has 50% left on it (two blue LEDs).I did experience one small issue. My phone will not charge off of the USB-C PD port (Motorola G Power 2020). Other devices work fine off that port. I believe this is an issue with my phone and not the charger. Maybe Motorola used a proprietary fast charging system for this model or maybe PD doesn't work with older devices. My phone works with the USB-A port though. It will actually display TurboCharge on the screen, which I haven't seen before even with the original charger that came with it.

Being on my phone all the time due to work this battery pack really help with traveling and I don;t have to frantically look for an outlet to recharge my phone. It last a long time before I have to recharge the battery pack again. It is lightweight so traveling with it is a breeze. My main concern is that the battery pack does get hot and I hope it not serious enough to damage my phone. Another thing is that it takes about 5hr to recharge which is fine if I charge it overnight. Otherwise everything work pretty decent except for the heat emitting from the pack.UPDATE: upgrading to an extra star for excellent customer support. This was originally 3 stars but upgrading to 4 stars. Customer rep reached out to give some options making things right for the battery pack not meeting expectation. Thank you for assisting me in this issue.

The product is exactly as described. It is kind of heavy and takes a while to charge, which happens for products that hold a lot of charge. It is absolutely terrific and a bargain price. The only thing that would make it better is a digital meter indicating how much charge is left. It has four little lights indicating full to no charge. It works, but that would be it if you make it better.

I've had this power bank for 3 years and it's still delivering as promised. The only comments I would have is that it's a little heavy. Many Asia & SE Asia airport security screening dudes ask to see it, but have always allow me to carry this 20 watt unit on.
