Customer Ratings & Reviews

I bought this as a replacement for a charger that I lost. It’s bigger than the one I had. It seems to charge a little quicker than my previous one. The salesperson said that it holds quite a few charges. So far so good.

Just a great power bank for any device you need to power. It holds charge really well. Also charges multiple devices with one full charge. Great product compared to "NAME BRANDS".

This battery has a large capacity so it lasts quite a while before needing recharging, and it charges quickly.

Great little battery pack. Hplds true to fast charge and standard charge. Was a life saver on cross country trip for multiple mobile devices simultaneously. Definitely recommend

The insignia 20,000 mah portable charger is a very reliable source of energy when you don't have an outlet near by, easy to use. It does take a while to charge fully.

With the current charger I am able to charge my iPhone 11 at least 3 times before needing to recharge the charger. Love this item & it’s great for the price.

This portable charger carries quite a punch and charges my mobile devices quickly and allows you to do it multiple times before having to charge the charger again.

With a full charge it lasted me days of plugging in and unplugging my iPhone as needed. Definitely worth having, although it is pretty heavy to carry around.

This charges my Samsung phone and tablet quickly. It will charge them both simultaneously and it lasts a long time. Definitely one of the better power banks that I have owned.

The Insignia 20,000 mAh portable charger packs a lot of power. It's easy to carry and very durable. You can receive multiple charges off a single charge. I keep it in my vehicle for backup.

Charges all my equipment fast and easy. This is an awesome product . I am always confident when buying any product from this company Insignia[tm}.

It stayed charged and was a great source of power for my international trip. The power bank is a little heavy, but worked fantastic and held a charge the whole week long trip while charging multiple devices

i had a smaller insignia one which was great but this just charges faster and not too bulky

Works as intended, but it is big and heavy. I would have given this charger a 5 star rating if it weren't so dang big and heavy. I bought this when it went on sale and the price was really good. I would not have kept this anchor if I bought it at the full price. If you are looking for a lightweight and more portable battery back-up to stick in a pack or a purse this isn't the one for you. And don't dare fall out of a boat carrying this thing because you will sink to the bottom of the ocean.

Bought this as a replacement for my old portable charger and so far it has been great. it charges quick and provides excellent source when my devices are running low.

I got this to replace a solar charger I had that broke. A little bit on the larger size but gets the job done when I need it. Battery life is excellent.

I bought this battery with the intent to charge my phone because the programs I would run would constantly drain the battery life. It is quite big in my opinion and takes up quite a bit of space in my small purse but I still like it cause not only will it charge my phone if needed but other devices. Will need charging cord for other devices.

My child lives in California and has had several extended outages that have extended beyond battery storage, so I got two of the items, this one to carry and a bigger one that will do laptop x 1.2

Longest lasting power bank I have ever owned and it is fast charging too. With this you cannot run out of battery ever

This is my first power bank & although it is a bit bulky, it can fully charge my phone 3 times before i need to recharge it again.
