The vest has a very good heating effect, and you can feel the warmth within a few minutes. And the built-in power bank design is also very convenient, which can be used for a long time without frequent charging. During the skiing process, it not only keeps my back warm, but also allows me to charge my phone at any time. The overall design is simple and comfortable, and it is also very convenient to wear, and it does not affect activities at all. I highly recommend it!

The heating effect is very good. Through the built-in heating element, my back and chest can quickly warm up, helping me to resist the cold. The best thing is that it has a built-in power bank function, which can charge my mobile phone at any time. It is very convenient and definitely worth buying.

This heated vest battery pack is really great! First of all, the battery capacity is large, and it can keep heating for several hours after a full charge, so you can keep warm even when you are outdoors in the cold winter. The size is moderate and easy to carry, and it is suitable to put it in your pocket or the vest's dedicated battery bag. The charging speed is fast and the durability is also very good, worth recommending!

Bought a heated jacket on an auction site and of course the battery was missing. So I ordered this and it works great. Used on medium for 5hrs and only used 15% .

I bought this unit as a secondary battery to use in a heated jacket. This unit is advertised as a 30,000 mah battery and the battery that came with my jacket is 20,000mah. That would lead me to believe that this battery should last longer than the OE battery, however, that's not the case. This battery lasts about 60% of the time (100% to 0% in just about 2 hours in my heated jacket on high setting) compared to the "smaller" OE battery (lasts around 3-3.5 hours, same jacket on same settings). It does a decent job charging my phone (Samsung Galaxy S20 FE), but would recommend getting a different battery, especially if using with heated clothing. Also, it should be noted that the lighted display stays on the entire time that the battery is being used, unnecessarily using battery life that should be spent powering whichever device it's plugged into.

Product said it was 30,000Mah yet I hooked it up to my heated jacket and withen 40min from turning the jacket on i went from 100% battery to 1%. I have 3 in total, a 7500,12k and this 30k and the 7500mah I can run on high for about 4 hours. The 12k one last a little over 5hours and neither go below 30%. Either the battery is recieved is faulty or it isn't actually 30k. I'll check it at work tomorrow to verify at 100% charge what the actual mah really is versus what I got when purchasing a 30kmah battery pack for my heated jacket and heated zip up hoodie.A bit disappointed.

I didn't get this to heat a vest, but it's nice to know it can be used for that if I every get brave enough to visit somewhere that is cold. I got it for some equipment I have that requires 7.4 Volts, which this product does deliver in addition to the regular 5 volts. I have a 5 volt pack and attempted to use it for the 7.4 Volt application, which did work somewhat but not well enough. This one with the 7.4 Volt supply works just fine.Before the battery pack arrived I was concerned about how I would be able to charge it, and thought it would need an extra cable of some sort, then when it arrived I was surprised and quite impressed with the USB C port that can be used to charge the battery pack as well as to charge cell phones and other devices from the battery pack.In one of the reviews I noticed someone tell about their disappointment in not being able to charge a cell phone and other devices. That person is quite incorrect on that point and should take a second look, regarding how the USB C port can be used to bring power into this battery pack from a charger, as well as how the same USB C port can be used to charge other devices from the battery pack.This serves my purposes well and at a good price as well.
