Anker USB C Power Bank, PowerCore Essential 20000 PD (18W) Power Bank, High Cell Capacity 20000mAh Portable Charger Battery Pack for iPhone 12/Mini/Pro/Max Pro/11/X, Samsung (PD Charger Not Included)

To say I love Anker products is an understatement. I’ve been using Anker chargers and power banks exclusively for about eight years now. We have Anker car chargers in both vehicles and several wall chargers at home and for travel, all compatible with our USB-A and USB-C devices. We always choose PowerIQ chargers for safer, smarter charging. The PowerIQ feature automatically shifts into a trickle-charging mode to prevent overcharging your devices.Back in 2020, my husband and I each bought a 20,000 mAh power bank when we upgraded to new phones that support faster charging. Before that, we both had 10,000 mAh power banks for our older devices, which didn’t support the faster charging rates of the newer phones.My husband used his 20,000 mAh power bank daily for his phone, PC headphones, and other devices. I have used mine a bit less frequently. After about four and a half years of heavy use, his power bank recently stopped holding a charge. When he looked into it, he saw the battery had puffed up, a sign of swelling in the internal lithium cells, which can happen over time. So he disposed of his. Since I haven't used mine as often, mine is still going strong.While it’s a bit disappointing that his gave out, it truly was a champ and served him incredibly well. We have no regrets about the purchase, and when our budget allows, we’ll definitely be picking up another Anker power bank.

Good product , was delivered promtly

I was incredibly confused on how the fast charging worked on this charger so let me clear it up now. This battery pack is optimized to work with USB C specific items, that means that both ends of the cord are USB C. If you have a Pixel or Samsung / other Android phone / a Nintendo Switch, then this unit will be ideal for you.Now, if you have a USB A to USB C / USB A / micro USB / lightning type of cord, it will still work, but it won't charge as quickly. That means if you have an iPhone or any other device that doesn't have a native USB C port, you won't be able to utilize the full potential of this battery pack.Clear as mud right? Now here's the deal with the way to charge the pack, you NEED a wall plug in that uses a USB C type of input. So, if you have a Pixel phone, congrats, you've got the right type of wall plug in! If not, then you do need to purchase a different type of wall plug in that has a USB C input.Everyone still on the same page? Ok, on to the performance! This pack is a beast in every sense of the word. It charges incredibly quickly, and you can use it upwards for at least a week before needing to charge it back up. It takes about 4-5 hours to fully charge back up and it's small enough that it fits into one of my backpack pockets. To put it in perspective, I could play my nintendo switch on high brightness while it was plugged into the battery pack and it still charged it up. I've even got third party controllers on my switch, which takes up more energy and it still charged it up!This is a very specialized type of battery pack that is built for folks who use USB C cables. If you're not a native Android user, it's probably a good idea to look elsewhere. Otherwise, this was a great deal and it really helps keep me and my wife charged while on the go and it's been significantly less stressful to know that I won't be left floundering with a dead phone. Hope this helps clarify some things for folks!

Excellent, high quality power bank for a lightning based iPhone 11

TL:DR - Anker is kind of a fantastic brand. You get exactly what's promised and the quality of their products is super.Reading the reviews I find that a lot of people complain about slow charge time or about it not appearantly the capacity it states. I haven't had this issues with my battery.I took some time to see how many times I could charge my phone and it fell just about on the mark. It wasn't done with proper instruments. I simply let my phone with a 5,000 mAh battery get close to 2% and the I would charge it all the way up. I got about 4 full charges until the battery stopped charging my phone. Ended at 93% which to me already is on the money but even still, there was a night I just left my phone charging as I slept so it definitely got more than it's fill.There's also complaints about charging the battery itself and again, I didn't find this problem with mine. I timed how long it took to fully charge and it was actually a bit shorter than the stated time. Just about 5:30 hours. I didn't even need an anker branded charger. I used this 18W charger I used already to charge my phone. People might be forgetting just how massive 20,000 mAh is.Charging my phone was also just as expected. It charged it fully just as if it was plugged to the 18W charger which is to be expected but you know... I kind of still didn't cause it's a portable battery.Overall, Anker is kind of my go to for when it comes to electrical devices. I don't see them cutting corners to get there products out and for that I trust their brand. I feel like my devices won't suddenly burn out cause of bad components or that the hubs won't provided the performance promised. Idk, you should definitely give then a try
