Charmast 20000mAh Portable Charger with 4 Built-in Cables & 6 Outputs, 20W Power Bank Fast Charging - USB C External Battery Pack for iPhone 16 15 14, Android, iPad, Tablet & More (Travel Essential)

So far so good. It has charged both our OnePlus phones, (8t and 13r) with like 20-30% battery to full charge and it still has enough to probably charge them both again. It has charging cables built in and they work great. It may take time to charge it up from 0 to 100 but nowadays what doesn't. I like it better than my Anker 20000mah and it weighs less also. It's nice to see the power percentage display so we know how much is left.

This power bank is the perfect backup to support all of your devices. It is nice and compact making it easy to carry in anything from a small clutch/purse for me, to a small backpack or even a diaper bag for a child. The slim design makes it easy to carry anywhere, including by tiny hands, during use by my young, six-year old son. It is about the size of a phone but packs SO much power for its compact dimensions. It is capable of charging my son’s iPad, both of our iPhones, and even my laptop computer SEVERAL times with a SINGLE charge. I only have to recharge the device itself about once every 2-3 days, and it, in return will power all of our devices several more times, before it’s internal capacity is completely diminished and expended.It also charges with amazing speed. In the time it has taken me to write this review, the battery power on my phone (iPhone 15) has literally increased to 100% from where it was (20%-30%) at the onset of preparation of this review. The 1-100% battery life indicator is very convenient, letting you know how much power you have remaining to be consumed . I love the fact that it is designed to INCLUDE the FOUR most common charging tips, already built in, eliminating the need to carry around extra bulky cords in order to simply facilitate the use the device. My son and I can literally and quite easily recharge our devices at the same exact time. It does also include two USB ports to connect different devices.I love this product so much, that I just bought a second, so that my son and I can each have our very own, when we venture out of the house separately. I find this to be such a great value for the money, that I have already decided that I will be purchasing more units as gifts for my son’s teacher, and friends and loved ones for the holidays this year.I have included photos with my review to help you reference the size of the product. There is a green power bank next to a green iPhone 15. The blue power bank is connected to an iPhone 13 mini.

The Charmast 20000mAh Portable Charger is a solid travel companion with its built-in cables and multiple outputs—no need to carry extra cords. It charges phones and tablets quickly, and the 20W output keeps devices powered up efficiently. The large battery capacity means fewer stops to recharge on the go. It’s a bit bulky for pockets but perfect for backpacks or travel bags. Overall, a reliable power bank that simplifies charging when traveling.

Love this brand, THIS STYLE made from this brand and the prices especially on Prime Days or Black Friday sale! I live in the low country so we are hit with tropical storms and hurricanes and definitely so without power for extended periods of time. I buy the 20000 now although I do own 1 10000. The 20000 will charge a newer iPhone about 3 times as well as a iMac Pro 1 time. I currently own 4 of these and will keep buying them. They are so portable have EVERY sized charger you will need, they are durable and sleek. They charge my devices quickly which is always a bonus! I keep these with me at all times. Because everything is on a computer, phone, iPad, kindle, oh and my camera batteries for work! Literally EVERYTHING can be charged with these! I love how the screen displays the amount of power left in the device and it’s never a worry when I hit 15%, I know I have my staple items covered for the day! If not in used I’ve had them hold a full charge for over a month which shocked me! I’ve traveled everywhere with these as well and have never had an issue on flights. GREAT option and LOVE that this is the only charger I have to take with me even on extended vacays! Just one cord to charge this and everything else is plugged into this (usually all at once when I go to bed)! Sooo simple to use! And one other GREAT feature, you can charge this in the wall while it’s charging all of your devices so you wake up to the power bank charged and ready to go again for the next day! These are PRICELESS! Definitely my favorite! I would recommend the 20000! I’m now working on stocking up my hurricane emergency totes with these as well!

Picked up two of these for a recent trip. One for me and one for my daughter. My lack of a 5th star is solely based on weight. It is a little heavy to carry around in a purse but I guess you have to trade off functionality for weight. I love the built in cables (one less thing to lose or forget) and love how quickly it gets charged and charges. I will be purchasing one more for a stocking stuffer for my son because the weight is not a concern for him.This is durable, comes with a fabric pouch to protect it and comes in nice color options. It is a great size to fit in my purse and the functionality is second to none! The brightness on the screen is not overwhelming and gives you the percent charged which is very helpful.

When I first got this, it was charged to 75% already. Tested it and it worked great. Plugged it in and let it charge to 100% and then set it aside. I needed to use it the other day (weeks later) and it was still at 100%. Nice! It charged my iphone 50% in 20 minutes. That was enough at that time. The battery on the pack only went down 5%. Nice! Insert doing this 4 or so more times and the battery on the pack only went down to 67%. Nice! We're supposed to get storms today so I am charging it to 100% now. It takes a long time to charge. (At 67% had it plugged in for 1.5 hours and is only at 83% now.)
