Quality product.
Fully needs my needs. And one of the few products that will charge my old iPhone 11 and my even older iPad. Just realize that it does take several hours to recharge fully. It came in at 81% charged and it took six hours to get to 100%. But now that I know that I can deal with it. Having the chords attached is great – you never go to charge somewhere and you don’t have the right cord. That more than meet expectations. It is a heavier product that you’re not gonna want to carry in your pants pocket unless you are wearing a belt but it feels really well made. They are doing a lot of building around me and I do have power outages, so I’m going to buy a second one. I’m so pleased with it. Just charge it up as soon as you get it and then instructions are to recharge every three months so it will be ready for you. Next day delivery! Have not had it long enough to review longevity of use.

Love this! Even bought them as gifts for friends
Great power Bank and it’s so convenient. Do you have all the different charging adapters already on the unit not having to look for extra cords charge a super fast as well

Good Buy!
Phenomenal product! Charges faster than any charger I’ve ever had. It even keeps my laptop charged. Doesn’t charge the laptop fast at all but it does give it a slow charge. If I use the charger daily, I recharge it over night. It will get down to 20% when I use it most of the day. It will recharge to 100% overnight. I wish you could see what the % level is without plugging it into my phone or to start recharging it. It would be good to have button you can push to see what the remaining charging % is. I would only buy a different one IF it was an even stronger charging one. But, I love the product for sure. Comes in handy often. I tad bulky and heavy but it works really well on everything I need to charge.

Great product and price!
I was super skeptical about this charger having the cords attached to it, but it works great! The cords fit very snuggly in their little form so it's nice to know even though I won't use certain ones often/ever, they're not going to just keep flopping in the way

Great little charger
Love this. It'll charge 3 phone and air pods on one full battery. Great for traveling

When You Need More Than A Basic Power Bank
The Charmast 20,000 mAh power bank has worked well for me. There is a percent-of-remaining-charge digital display plus four convenient six-inch long, permanently attached cables that store in dedicated slots on the rear of the unit. These provide charging connections for USB-A, USB-C, micro USB and Lightning devices. There are also two USB-A output jacks on the body of the unit should you want to use longer cables when charging your devices. This is a higher capacity power supply than most pocketable power banks. As such, it is a bit heavier, and it takes longer to charge, typically, around six hours using a fast 18 Watt power supply. I checked to see if the 5 volt output voltage from the outputs I tested fluctuated with current demand. While I didn't test every output, I did find that the red USB-A jack (Output 2) on the body of the power supply was the most stable one I found by never dipping below 5 volts even with a 3 Amp resistive load. Other outputs I tested (without exceeding their manufacturer's maximum current ratings) were not quite as stable. However, none dipped below 4.5 volts in my tests, which still allowed my connected devices to charge effectively. (I took one star off my rating due to this issue, since some unusually sensitive devices might exhibit issues with the low applied voltage.) Like many power banks, this one turns itself off when the charging current falls to around 30 milliamps or below. Note that most devices are at or near full charge when this point is reached. If you have a small device that requires low charging current to reach full capacity, the power bank can be placed in low current mode by pressing the power button for a few seconds until the display animates. Devices that require charging current below 30 milliamps will now charge fully. However, the power bank will have to be manually turned off at the end of charging by pressing the power button twice (this also returns the unit to normal automatic power off mode). This charger has some nice features. This includes its built-in multi-cable connectivity plus the ability to charge multiple devices, and/or charge a single device many times due to its relatively large 20,000 mAH rated capacity. It runs cool and without any surprises. Recommended!
