This little thing packs power
I bought a different brand of this because I saw it on Today and I have been traveling a lot for work and the other was always running out even if I did not have huge delays. I came back to buy another one of those but this one had better reviews and it cost the same so I bought this. What a difference!! I have been using it at home to test it out. It takes longer to charge but once it does it charges my phone quickly even when it’s at 50% and remains over 80% after doing so. There is also an adapter to charge a lap top and a few other types of devices. Highly recommend.

Great portable charger
Love love love this charger! It takes some time to fully charge but once there, it charges multiple phones from basically 0 to full charge, and fast! It's not overly bulky and I like the built in cables that do not get in the way when not in use. Highly recommended

Nice product
I like this product a lot. Charges my phone fast in about 35 minutes or so as it sapped the power bank by about 20%. It's well designed, durable, and a bit heavy. Using one of the four cables to charge devices is amazing. Would recommend a lot! I like the small travel bag that came with it. Good product.

Great purchase- works so well
I love this charger. I have used it everywhere -traveling, for my phone, computer, various accessories (kids iPad, portable fan, bottle warmer, anything and everything). The different plugs make it compatible with basically any charging port. The battery life lasts a very long time. I’m able to fully charge my iPhone multiple times before having to charge it. Size is similar to an iPhone, however it is a bit heavier. Charging it doesn’t take too long considering how much power it provides once fully charged. Very happy with this purchase.

Lots of power with lots of options!
This power bank is incredible! I love that it has the 4 most common plugs already attached. This feature has enabled me to use it at work for the iPad that is always dying before I am able to finish my task. It's great in the car on long journeys because I can charge both my phone and my tablet and still use them regardless of where I am sitting in the car. It charges both my android phone and my android tablet quickly. It's been an all around great power bank and I highly recommend it.

Useful
Great power bank! Can get two full phone charges. Slim and compact. Takes a very long time to get the power bank charged.

YES, IT'S WORTH THE EXTRA $20
I've used a number of different chargers over the years and this is hands down the best and well worth the extra $20 or so. Here's why: 1. It's Fast. The Charmast 20000mah Power Bank comes with 20w charging speed which meant nothing to me when I ordered it but now I know it means my phone will be charged quickly. I have a new Iphone and Apple's expensive charging cord and pack are probably as fast as this, but they certainly aren't faster. 2. Built in Charging Cords: The built in charging cords are a huge benefit. No more looking for the right cord, no carrying around multiple long cords that don't seem to fit properly in my car, jacket, or bedroom. I can charge multiple devices at the same time, but mostly I use it for my phone and have ditched the cords. 3. Long Lasting Battery Life: I use to keep 2 of the $20 phone charges on hand so that I could swap them out once the battery died which seemed to happen after only a couple of uses. This charge seem to last 4 times as long as those other versions and it has a built in display that tells you exactly how much battery life you have left to use. I went on vacation and used this charger for my airpods and phone (in addition to wall charges at night when possible) and it lasted the entire week without needing to be recharged itself. This also quickly turns itself on when you plug a device in and off after you unplug. Other devices I've had needed to be manually turned off and if you forget then the devices runs out of battery. 4. LCD Screen Showing Battery Life No more guessing if you should recharge your charger. Theres an LCD Screen that shows how much battery life is left and that makes life easier. To Sum Up: Spend the extra $10-$20 and get an All-In-One, Long Lasting, Quick Charging device.

Stopped Working Properly
I bought this to use on a trip and it worked well the first few days. After the third day, it would not charge my phone. The battery would be charged, but when I plugged the cable into my phone it would not start charging at all, or start charging for a minute and then stop again. I'm unsure if I got a faulty device or if this is a common issue but I'm disappointed with my purchase.

Good reliable charger
I bought this about 6 months ago and it’s still holding up well. I use it a lot especially when I am travelling. It is great to always have a backup battery on hand. Plus- charges fast, built in cables, still working well. Minus - wish it had a built in plugin attachment, a little heavier than my previous one I owned Overall, I’d recommend because it has held up better than other battery packs I have owned. All cables are still working well. No issues after a lot of use.

The perfect all-day all-device charger
I absolutely love this charger, and keep buying more of them. Having the cables built-in means that you just have everything you need in one unit, with no other cables, or sometimes not even a plug, needed. I even travelled abroad for a week, completely forgetting my laptop and phone charger, and managed to get by with just this. I plugged the USB-A input into the hotel USB-charging socket overnight, with the USB-C output plugged into my iPhone. Both were fully charged by the morning, and then I used it to keep my MacBook Air charged during meetings over the day. I wouldn’t recommend it, but, heck, it worked! It also was enough to keep my iPhone and my MacBook Air running over a full day at a conference, again with no other cables at all required. It just answers every use case you need it to. Plug it into your airplane charging socket to keep your phone charged? Done. Charge your laptop by USB-C? No problem. Charge your USB-C iPhone and kids’ Lightning iPad? Sure. The only thing it can’t do, is charge by plugging the USB-C cable into a charging socket as an *input*. There are more USB-C sockets in Ubers these days, and for these, you’ll need a cable.

Great, but charge overnight!
This is great ! I love that it has all the chords attached. It charges really fast , but it takes a while to recharge. Charge overnight. It's a bit on the heavy side, but it packs a lot of power.
