TECHSMARTER20000mAh 30W USB-C PD Power Bank, Portable Phone Charger Compatible with iPhone, Galaxy, iPad Air/Pro, MacBook Air/Pro, Chromebook, Androids & More

Recently purchased this charger and all I can say is WOW, this charges so fast. I plugged two phones in at the same time that had gone dead a Galaxy S10 and an Iphone XS and it charged both full from 0% to 100% within 1.5 hours and had plenty of charge left to do the computer.The compact size and sturdy build make this charger dependable and versatile and 30W Power is really impressive. This is a definite buy and with the holidays approaching I am thinking of buying more for gifts. I recommend this purchase for everyday use.

This power pack is perfect for traveling and taking long day trips. I purchased it to hook up to a shoulder bag that has a built in USB for charging. It fits nicely in the bag and works like a charm when walking around. My family and I spend a lot of time at Disney, so it's super convenient to have a dependable battery pack with us.One of my favorite aspects of it, aside from the super quick USB-C charging, is the ability to charge multiple devices at once. This keeps me from having to wait until my wife's phone is charged to use it.One thing to note: I don't feel that this is a power pack that you'll want to carry around in your pocket. It's a little heavier than most I've used. I ordered it specifically to keep in a bag, and it does the job nicely.So far I've charged a phone 4 times on one full charge of the pack, which is pretty impressive.

Bought two, one broke a month after purchase, would not recommend for daily carry.

Charges well, easy to use.

Thing just didn't work

Your browser does not support HTML5 video.  As with any other serious charger (and I would consider this to be one), this thing is fairly heavy and massive. You could probably defend yourself with it if it came down to it. Hopefully, that will never be a legit product feature. Anyway…Stuff to know:-This easily has double the capacity of any charger we have.-It has a 30-watt output.-It offers quick charging capacity on the USB-C and one of the two USB ports.-The USB-C offers power delivery.-You can charge from the micro USB port on the side, but even though it says it’s 12 v and 1.5 amps, it feels slower for some reason.-You can charge the battery pack from the USB-C output charging port.-It has a nice textured case, which makes it easy to grip.-I ran a quick discharge test on it, and for over 5 hours it produced 5 v and 2 amps.-I like the power options on it, but I’m not sure why they included a substandard 5V 1A port. I would have preferred at least one more high-speed charging option!-30 Watt output was not powerful enough for my 15” 2018 MBP

This solidly built multi-purpose power bank outperforms others and is in a class of its own. It reflects a new generation of power banks with smarter circuits and more output. It is not lightweight, weighing in at 1lb, 3oz. It's 7 inches long, 2 3/4 inches wide, and 1 inch thick. If you're willing to accept its size and weight you'll get an incredible power pack.It's capable of charging and operating a variety of devices including smart phones, tablets, laptops, powered speakers and other devices which require relatively high wattage high Amp Hour input. I'm using it with an iPhone XS, iPad Pro, Sonos Move and Bose Portable powered speakers. It will recharge them several times from fully drained batteries. It would be perfect for long haul flights or use in areas and at times when A/C power is unavailable or impractical.The pack itself is streamlined despite its size so it will slide into backpack pockets. It's too large and heavy, in my opinion, to carry in your pocket or jacket unless you are wearing military BDUs or similar with deep pockets. It has a recessed on/off button on one side. It has multiple inputs and outputs to meet a variety of power demands.Charging and Inputs: It charges via a micro USB input only port or USB-C input/output port. Three very short cables are included with a variety of connectors. I needed longer cables which I already own. it will charge fast via the USB-C input/output port connected to a high wattage (30-65) USB-C A/C wall adapter. No wall adapter is included. Otherwise it can be charged via micro USB input port with any USB wall charger. A charging LED along with 4 battery level indicator LEDs reflect battery and charge status. I tested charging it with a 65 Watt USB-C smart A/C wall adapter and it took about one hour to fully charge from being 75% discharged. That's fast.Outputs: 1 USB-C PD 30W input/output port and 2 USB-A output ports.- USB-C -- 5V-3A, 9V-3A, 12V-2.5A, 15V-2A, 20V-1.5A- USB-A Output Port 1 - 5V-1A- USB-A Output Port 2 - 5V-2.4A, 9V-2A, 12V-1.5ACapacity: 26,800mAh, PD30WattsThese power figures indicate it can charge and power virtually any device which has a USB-A or USB-C input. It may not run a laptop without its built-in battery but it will certainly recharge almost any laptop battery. As for any other compatible device it will recharge or run that device with no problem.This power pack, while hefty. tops its class in build quality, smart circuitry, power output, and connector options. If your needs warrant, this power pack is highly recommended.

There are a ton of power banks on the market and most of them are pretty good. This one from Techsmarter blew me away with its in/out quick charge ability.I own power banks that I purchased a couple of years ago that only have 10kmAh and those take 18-24 hours to fully charge from zero. This one from Techsmarter completely fills up in less than 4 hours. Because of the size of the battery, I can recharge tablets a couple of times and phones a few times before I need to recharge the power bank again.I can't tell you how many times a power bank has saved my bacon at the office or the gym when I really needed my phone or headphones to work. This power bank allows me to include tablets to that list which is very important to me as I never turn my tablets off. Having a power bank that can fast charge my iPad is game-changing because I don't manage or monitor its battery as vigilantly as I do my phones.The only shortcoming of this power bank IMHO is the lack of ports. I wish I could charge 4 or 5 items simultaneously with a power bank that has such a large capacity.Despite the one area for improvement mentioned above I really like the usefulness of this power bank. Having a recharge time of 3.5 hours makes keeping the power bank juiced up far less of a chore than it is for anything else I own which is why this one is the one I use most often.
