Vinsic Terminator P3 20000mAh Power Bank QC3.0 Quick Charge 2.4A Dual Output

amazing portable power source

Well designed, sturdy, charges up my two phones super quickly. While I haven't tested it with an ammeter or anything, I am quite impressed with how well this functions compared to more recognized brands (dare I say, quite superior). This external battery arrived charged for me 3 (at about 60-70%, I forget). The capacity rating of 20,000 mAh appears to be correct, as a full charge of my iPhone 6 takes it from 100% to 89% -- consistent with the fact the iPhone 6 has a 1810 mAh battery, and an estimate of 80% charging efficiency after accounting for internal resistance and heat loss (generally a fact of lithium ion charge/discharge physics, regardless of manufacturer). It takes about 3-4 hours for it to charge from 48% to 100% with my USB 3.0 cable. (Competitor versions would take twice as long.)

It's definitely my to-go battery for my extended outings out and about in New York City now! And it's very stylish! AFAIK there are no weak points yet (the weak point on the Limefuel batteries for instance, tend to be on the micro-USB power input port into the battery) but I've only had it for a little less than a month now. Overall, there's so much juice in this thing I have yet to exhaust it!Read full review

Not bad

But there's no way this is 20k ma. It charges very fast, but it also takes a whopping 45% of its charge to charge my 4800ma phone battery, and that's only if it's down to 20% Still, for the price it's well made and easy to use, and provides fast charging.Read full review

It's got everything!!

So... My girlfriend's phone has quick charge 3.0 and mine USB C. I could find a power bank that had both for under $60. After, literal, months of searching I came across this one. I already knew that Vinsic was a reputable brand because everyone on YouTube raves about their 20k mAh super thin power bank but I had never heard anything about this one.

Searched google and not a lot came up, but I decided to give it a shot and It was totally with it.

It has QC 3.0 and USB C output 3 amps max. The USB C also work for charging it but at 2.4 amps max. It also has a smart USB port and a mini USB for charging. In summary, it has 1 input port, 2 output ports and 1 in/out port. It has a digital battery % readout that's touch sensitive.

I charged my phone for 3 consecutive and my Bose Bluetooth headphones for 3 strait days; about 4 times each one.

The only drawback it that the battery is big. It's about 4" x 6" x .75" and it weights 14.7 oz (418g): almost a pound! So, if your looking for a pocket size battery for a quick refuel, this is not the one. That being said, this battery will give you several charges on different devices so it's perfect for power outages, camping, charging USB C laptops and other instances where you'll find yourself without an a/c outlet for a couple of days. Is you manage to completely drain it, it charges in about 8hrs through a USB C charger.

I definitely recommend it. For $35 there is no better power bank out there.Read full review

Good Power Bank

Don't think 20,000 Mah is correct. It will fast charge my cell phone and tablet at the same time, with 14% still available on bank. Been using it for a few weeks with no problems.

Necessary travel companion

The PERFECT daily companion for daily use, but ABSOLUTELY NECESSARY for any kind of travel, trips, events, or even just a day running errands. Pairs well with a Quick Charge/QC 3.0 compatible device and cable, and for iPhone folks a USB-C to Lightning cable will be an absolute game changer. Charge your phone from 0% to 100% in a matter of MOMENTS!! No more laying your phone to charge for hours at a time -- charge it QUICKLY and charge it WITH YOU AT ALL TIMES!!

NOTE: this WILL charge a 2016 (and newer) MacBook Pro, it's mainly how I charge mine when I am working mobile or just walking around the house with my laptop... those of you who work from home will understand! It will also charge your Nintendo Switch via USB-C!! It has a QC 3.0, as well as a regular speed USB port. All together you can charge THREE devices at once, 2x USB-A and 1x USB-CRead full review

USB type C & then some.

Great product! Fast delivery, great price! I have the new MacBook Pro which is USB C, but hence it's such a beast it won't charge with this devise unless it's completely powered off. Other than that minor issue, thank you!
Fast shipping was fast too!Read full review

THE best portable charger!

I'd give this charger 10 stars if I could. This is faster to charge my phone than my quick charge wall plug that came with my Moto Z Force. It does take about 12 hours to charge it from the wall from about 30% to full charge, but that's not an issue for me. I just plug it in & let it charge over night. The thing that is so awesome is when I charge my phone from it. It will take it from say 20% to 75 in about a half an hour. I've never seen anything so fast. It doesn't heat up while charging at all. It stays cool to the touch. The readout telling you the percentage that it's holding is very handy. It's so easy to tell how much charge it has left. This is a very quick charger. I'm beyond happy that I chose this one when I was shopping for a new one. I definitely recommend this little device. BUY IT!!!Read full review

Very good dependable power bank

Gave this to my wife as a gift. She is in retail sales and uses her cell phone and tablet all day long, she doesn't know how she managed to do so before this portable battery. It is very well built, it feels of great quality. It has an LED display showing charge capacity. On a full charge it will charge up to 5 times the tablet and cell.Read full review
