Good Buy!
Phenomenal product! Charges faster than any charger Iâve ever had. It even keeps my laptop charged. Doesnât 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.

It’s really comes in handy!!
My sister purchased a charger for herself telling me how handy and convenient it is I liked it so much she purchased one for me. I showed it to my friend, he wanted one also, I purchased one for him it was here in 3 days. The charger is light in weight, fast charging, easy to carry and a must have for hurricane season. Easy to carry with you at all times multiple charging units. It can be used with all phone types of phones, other equipment also. It also has 2 usb ports. I love my charger.

Good, light, charger keeps me going for an afternoon out at the beach.
This is a goodie as I can help charge my friends that have different phone plugs. I feel confident to take to the beach where Iâm taking photos and be able to make it through the day. So far itâs been consistent. And itâs light and easy to throw in my bag.

amazing charger
THIS RIGHT HERE?? this charger is amazing. it charges your phone so fast or any other thing that you need to use because Iâll be charging my headphones with my speaker with it when Iâm out and itâs so portable I canât . The size of it is just like having another phone in your bag, but thatâs no problem when you know that this has four cables and can charge anything that you need to charge. and it doesnât die fast at all.

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!

Charger you need!
Love my new charger. Itâs small enough to carry with me and large enough for me not to lose it! Charges pretty quick and definitely worth the money. Lots of different colors too. The pink is so pretty.

the weight of this unit
The product worked for my iphone even though it is in a water tight case but itâs still quite heavy and large.
