So far, so good. It charges my cell phone pretty fast, and the charger keeps its charge for days. It took a couple of hours to charge it initially, but I don't let it get down too low to have to charge it that long now. OAN, I have yet to charge two items at once with it, so I don't know how fast it would take to charge in that case. I am pleased with ther product.

This is a well built massive compacity portable charger it's lightweight supports high speed charging input and output so far everything works perfectly I would have loved to have a USB type-c to type c connection but other than that for the price you just can't beat it and in this day and age you never want to be caught without power for your mobile devices

Charge your mobile devices with this Insignia portable battery. The Qualcomm Quick Charge 3.0 port delivers power rapidly and securely by self-adjusting the output, while the four LEDs display the charge status. This Insignia portable battery has a 20,000 mAh built-in cell capacity, offering ample charge for uninterrupted use, and the dual-port powers two devices simultaneously.

It’s a bit heavy but charging is quick and standby life last for days.

Got this during one of the Deal of the Day sales. It came in handy during a recent power outage. Charged 2 phones quickly without a problem and still had enough power to charge additional devices. It’s kinda big and not designed to be portable. We plan on using this when having to spend all day at volleyball and baseball tournaments.

I lost my old unit and needed a replacement. I use it every day at work and it is invaluable. I like the larger unit due to the fact that it lasts longer. The 20,ooo mAh unit is the right size. Make sure you buy a large enough unit to meet your own needs. A smaller one for occasional use may be better suited for you?

Does exactly what it is supposed to do. It will hold a charge for months. I had it partially charged when I placed it in a drawer and did not need it for several months. I was surprised that it still had a charge and powered up my phone battery in no time. When I travel I am never without it.

With 20,000 mAh this portable charger can charge multiple devices. Just for reference, most portable chargers are around 5,000 or less. I can charge my iPhone 11 Almost 5.5 full charges with this charger whereas other smaller portable chargers may give me around 20%.

This little device is awesome. I use it everyday and it charges at a great speed. I got this at a great price and I bought two. My husband really loves his too. It’s a little heavier than I would like but the speed of charging out-weighs that. Would highly recommend.

I bought this during the nyc week long blackout and it was the best purchase I've ever made. It charges your device very quickly and holds a charge for a long time. Would highly recommend it for travel, conventions and in case of a power outage.

A lot heavier then expected, not something to carry in your pocket or purse. But I have charged my IPhone five times with the charger and it still shows three out of four lights of power left. This will be great for charging multiple devices.

The more I buy insignia products the more I like em. Awesome charger, long lasting and quick charge!! ...own smaller insignia power banks, by far the best yet.

It’s bulky and heavy to carry in your pocket. I’m a back pack carrier usually everywhere I go. I throw it in there and all is good. It charges phones fast. Although the battery itself is slow to charge

I bought this portable charger two weeks and it works great, it charges my phone about 4 times and my samsung tablet 2 times. It's not as heavy as some other portable chargers I've owned. I highly recommend it.

This portable charger can charge your phone multiple times without being recharged. That’s great if you are traveling and don’t want to be bothered or worried about recharging it. It can charge two phones at the same time. Love it.

This a great purchase. Exceptionally handy to have when you can't charge your phone from a wall charger. It holds it charge for days, depending on how long you use it. This was a great purchase.

Very reliable great turbocharged feature for your phone or tablet convenient travel size and you don't have to charge it everyday you can charge it every two to three days and still charge your phone or tablet only thing is it's bulky but that's all right.

This portable charger has a large capacity for it's size. I can charge my phone 8 times before having to plug this in. The price is the best I found for the number of mAmps. The reason that I have it a 4 is because it's a bit bulky and a bit heavy.

The device is so convenient that I can charge my Note 20 Ultra 3 times in a single charge of this Power bank. Its fast charging is very powerful that I can charge my phone very fast.
