Purchased this battery to have an extra battery for my coat. Charged fine, nice to have if needed.

Good price, small, lightweight. Works as a battery for a heated vest I bought as a gift. I honestly believe this also works as a power bank, it’s very portable and can be of use to charge devices.

Always good to have extra power

Good product ,shipped in reasonable time. Bought for electric vests, should go with 10,000 Mah to last for entire round of golf. No complaints on quality.

I will by more products in the future

When I received the power bank it was already partly charged, so didn't take long to fully charge and works great in my new heated vest. Thank you for a good product.

I have some other 5V power packs, but the flat design of these is excellent for my heated vest, which is why I purchased this second one. I did a test with the battery that came with my vest, and it lasted about 4 hours on the low setting (which seamed plenty warm). The order came quickly and was as described. I would buy from this company again.

I am happy with the power bank. I previously bought the wrong battery pack elsewhere years ago and I'm very happy to have found this and it fits right in the pocket as expected and works Great

Works well

This battery is a huge improvement over the original big thick battery.

I used it for hunting this year. Held a charge about 6 hours in high.

Very pleased! Quick Delivery! Highly Recommend!

This product works awesome

Always buy an extra. Then use it all year to power up your phone. Then the battery is ready for winter!

Somehow lost my battery and cable for my heated hoodie, so bought this as a replacement. Glad to see that you let us buy these small items separately. Great service!

Charges my shirt and my phone! It's got a large capacity to hold enough charge.

I liked the color and the smoothness of the battery, but the charging cable is too short to keep the battery on my tabletop. It charges my phone.

It was easy to charge the battery up and use it as a backup battery for my ActionHeat jacket. The casing gets easily scratched though.

Even if I charge the battery fully overnight, the battery does not stay powered for a full 5 hours after leaving the sock on.

Needed a replacement battery for one we lost hiking, i was able to get just one and not rebuy the whole set of socks, that was nice.

Power bank works perfectly even after a year so I've bought another one for my set! Thanks again for making such a strong product!

I thought my jacket was the best investment I ever made but then I bought an extra battery xD

Always a handy thing to have on hand and i can use the cable and plug on my other USB devices. Quality is excellent.

This is a really good product and at an affordable price. Heat continues to flow! Woo!

I wanted an additional battery for the puffer jacket my daughter gave me for Christmas and was so happy to see that I could buy just what I needed and nothing else. Shipping was fast and simple. Blessings.

Decent price, easy to use, and I love the versatility of the USB.

$40 for a spare battery seems like too much.

I bought a heated base layer top and a heated vest, which I never wear at the same time. They both use the same battery, so I just bought one spare so I can keep everything on for the whole day.

Extra battery for the heated jacket I got as a gift. Price is excellent and shipped quick.

I wanted a powerbank so I got this one. It even has a flashlight!

I have the heated vest (which I love) and wear it alllll the time, even at work. I bought an extra 6000 battery to keep the heat flowing, and then I bought another one, so I'm never not heating. I seem to just continually swap the batteries no matter where I am and having the kit makes sure I've got the charging cable everywhere too. Awesome products, Action heat!

I dropped the battery that came with my jacket and needed another one. price was a bit high, but it was my fault I dropped it, so I got this one.

Strange to leave a review on a battery and charger but here I am. I needed a power sourse for my phone and wasn't happy with the ones I found on another site that won't be named--2 day shipping was going to take 10 days! but actionheat got this to me in just a couple of days and that was great. A++++

I needed a new battery to heat the shirt i bought a year or so ago. this fit the bill.

I wasn't happy at first that i needed to buy another battery just to stay warm, but now that I've got a couple, I admit it's pretty sweet. Drop the price and I'll buy even more.

Great battery, also works to charge my phone

I purchased heated jackets for all my grandkids and also purchased these extra batteries so they wouldn't ever be cold.

Always have to have a spare battery ready to keep on heating. best decision ever. Shipped fast.

Wish the battery power would last a little longer, but it's fine given how long I wear the premium gloves in a day when I need to.

The battery kept my daughter's jacket charged for a good amount of time during her trip up the Poconos. The jacket stayed warm for about 3 hours for her, a good amount of time considering how long she was outside.

Great service. Thanks!

Ordered this battery. Highly recommend it when you need spare power for keeping a jacket or base layer on the highest temp setting.

Bought this along with the Action Heat vest as a gift for a friend. The battery itself is works very well. Carries enough power to heat a vest or any electronic device for emergencies.

What I like about this power bank kit is it's multi use.

I used these and they work very nice it is getting cold where I live and they lasted for the whole event

this battery really powers my heated gloves. Packs a punch!

Handy and durable battery pack to have

Perform as advertised

I would give it a 5 start but it dont last that long. If you plan on spending the day outside plan on coming in to charge it.

The battery I ordered is exactly what I neeed
