Description

Why is my power bank providing fewer charges than expected? The capacity reduction during charging is due to a 30% to 45% energy loss in the battery cells and conversion circuitry. Therefore, a fully charged Anker A1383 Power Bank (PowerCore 20K) offers an estimated 11,000mAh to14000mAh to power devices. How can I estimate the number of charges for my device? To estimate charging cycles, use this formula: (Power Bank Capacity x 0.65) + Device Battery Capacity ≈ Numberof Charges For instance, charging a 3,500mAh device using a 20,000mAh povver bank would offer approximately 3.8 charges How long does it take for the power bank to recharge? It depends on the charger's power and the ambient temperature. The A1383 model, when using a 30W PD charger at 77°F (25°C), takes about 4.5 hours to recharge.

Lasted two full years of heavy charging and use
Color: Black
Two years of full charges I used this almost daily and found the simplicity and versatility of the charging options ideal for my needs. Eventually, the battery indicator started glitching and it would sit at 10% for a long time (while charging my phone to 50% in less than 30 minutes). It is rather large, but it stores well in a bag and the built in cable makes it great on the go. I never had an issue with it overheating and found it could charge steadily multiple devices with little heat output. I took this thing everywhere. On planes, internationally, hiking, camping, and on my daily work commute. It has come in handy so many times. Unfortunately today after nearly two years of portable charging, it finally died on me. The screen stopped showing a percentage and devices no longer detect its power. Alas— Now it’s just a brick and I will be looking to purchase a second one. Worth every penny. ... show more

A Reliable Travel Companion with Convenient Built-In USB-C Cable
Color: Black
Review Image by Jesus
After using the Anker Power Bank 20,000mAh with the built-in USB-C cable, I found it to be an excellent choice for reliable portable power. The integrated cable is one of its most convenient features because it can be used to recharge the power bank itself and charge many Android devices without carrying an extra cable. For Apple devices, using a certified compatible cable is recommended to ensure proper charging performance and compatibility, since Apple devices may use different charging specifications and power management systems than many Android devices. The power bank delivers fast, dependable charging, and although it is slightly larger and heavier than smaller models, the extra battery capacity makes it a great option for travel, work, and long periods away from an outlet. Overall, its convenience, performance, and build quality make it a highly recommended product. ... show more

GREAT Customer Care
Color: Black
This is our goto Charger, after about 8 months of rigarous use - the cable stopped working, but the battery was still working great. after another two months the battery stopped charging and I wrote Anker customer care. They immediately replaced the product. The new one is now our goto charger, and we recycled the old on. with all the other batteries I have bought from other places, I have never gotten this great of customer service after purchase. Now all our charging is done with Anker. its a great size, and works with everything we need. And at even 12% battery, last night it immediately charged my phone to 40% from 5%. which was a life saver. ... show more

Excellent power bank for travel, hiking, and everyday use
Color: Black
This power bank has been one of the best purchases I've made. I originally bought it for backpacking the Devils Dome Loop Trail so I could keep my phone and headlamp charged, and it worked flawlessly throughout the trip. After using it in the backcountry, it quickly became something I carry with me every day. My iPhone 13's battery isn't what it used to be, so it's nice to have a reliable way to top it off whenever I need to. It's also been great for my camera gear. I regularly use it to charge my GoPro and Canon camera batteries, making it a great addition to my photography kit as well as my hiking gear. One feature I really appreciate is how quickly it charges both itself and my devices. The built-in USB-C cable is also incredibly convenient since it's one less cable I have to remember to pack. Overall, this is a high-quality power bank that's been reliable whether I'm backpacking in the mountains, traveling, or just going about my day. It's well built, charges quickly, has plenty of capacity, and has easily been worth every penny. I'd definitely recommend it. ... show more

Best of breed for aggressive road traveler use 🌟🌟🌟🌟🌟
Color: Black
I have used a ton of batteries and power banks over the years, and this is one of the best in terms of the balance between size, power, and usability. I have used it almost daily for over a year and never a problem. I travel with two. As long as I have one charging while I'm using the other, by swapping them back and forth, I never run out of power while *simultaneously* using it to power a laptop, iPhone, and iPad. Important to note that this use case assumes you recharge the Anker Power Bank from a device that delivers least a 60W+ charge via USB-C PD, as the Anker Power Bank happily accepts about 63W max which is why it can recharge so quickly. This is also the largest capacity power bank that's technically permissible under a conservative read of international air travel rules (FAA/IATA). Although you rarely get larger ones confiscated at airline security, it happens, like to me in a country where following rules is a national pastime 🇩🇪👀😆. ... show more

Solid. Fast charging. Multiple charges.
Color: Black
Great power bank. Able to charge my phone several times. And charges my stuff fast. A little heavy but it’s 20,000 mAh so it’s expected. Took to Italy with me last year. Great to have on hand on the move. Decent size slight bulky but I wanted the higher mAh.

Its accurately priced for what you are getting
Color: Black
I’m going to keep this short and sweet Pros: 1. Looks and feels nice. Not too bulky 2. Holds power decently long. I get about 20hrs of recharge from a full battery cycle 3. I like the display of how much juice is left. (Its not accurate) 4. Built in type c cable is nice Cons: 1. The display is not accurate. It runs from 30% to dead in about an hour. This should take about 5 hours of charging to do based on the rest of the battery life 2. The type C cable is short. Its utilitarian mostly but it does give you a “second charger” capability 3. There’s only 1 USB port. This one hurts if you like me and use this daily. I end up having to juggle cords to keep my devices charged where i work 4. When you leave a cord plugged in to the power cell longer than 10 minutes, but NOT into the device, it will not charge the device until you unplug the cord from the power cell. Gripe but it is annoying 5. It doesn’t recharge very fast. It takes at least a day if not 2 days to recharge it to full 100% from 0%. Overall it’s a nice thing to have. Id pay about 40$ for something like this and feel like i didn’t get ripped off. Anything more and you could go elsewhere and get more quality ... show more

Great battery. Built in cable. Fast charging.
Color: Black
I love the fast charging of the battery and the built in cable. You can charge the battery from empty injust over an hour (with a fast charger), so you can refill at the airport during a layover. I use it for a medicine cooler, so having a full battery for an overseas flight is important to me. This works. The battery that was sold for the cooler may be the same size, but the lack of fast charging makes it less useful. The Anker battery is perfect for my needs.i love it. ... show more
