I snagged this battery pack as a backup for a heated jacket I purchased for myself this year. I love having it for the cold months, but remembering to keep it charged and having to pull the battery out after every use to top it off was such a pain that I almost regretted buying it. This backup allows me to have one fully charged battery on-hand for when I need it. I can now run the battery I have in the jacket down to zero, then just swap in the spare and be good to go while I recharge the one that is empty. It adds a good deal of functionality. The battery is rated at the exact same 20,000mAh as the pack that came with the jacket and it lasts at least as long as the one that came with the jacket, which indicates they are close to the same capacity and quality. Using it in my jacket is similar in every way to the one that came with it. The heat is just as consistent and I can't feel a difference. It's a reliable power source, and I love that it has 3 different DC size plugins for different jackets, plus USB-A and USB-C. It also has a battery percentage display right on the front, unlike the pack I had which relied on the 5 LED light system to show battery level. This is much more precise and lets me know down to the single percent where the pack is at. This is definitely worth grabbing, either as a backup to swap in when you charge one pack, or just to double your overall battery life on long days or nights out in the cold. Read more
I picked this up mostly as a spare battery pack for heated vests and jackets. What I like about it is that it has all the common DC plug sizes built in, so it works with just about any of the generic heated gear on Amazon. A lot of battery packs only have one specific connector and you have to match it exactly, which gets annoying. This one has been easy to swap between different vests without thinking about it. It doesn't get too hot and feels high quality. It’s been nice to have on hand as a backup, and the display makes it easy to see how much charge is left. Read more
Nice big battery pack - judging by the size this seems to be a full 20k mah pack as it is about twice as thick and heavy as my 10k packs. So far I've used this mostly to recharge USB devices and it works fine for that. I appreciate the various sized ports for heated vest compatibility and it can charge two devices at once over its two ports. Read more
I ordered this as a backup battery for our heated jackets and also heated blankets. You can never have enough backup batteries in cold weather. The quality is excellent, it is 20000mAh, so it is longer lasting, and it has many ports for various situations. It is larger than the standard 10,000 mAh battery. Read more
Mostly bought this for the battery capacity to charge my phone and stuff on the run where i dont have an outlet. Lasts a long time. Id definately get again. Read more
I got this power bank as a backup for my heated jacket, and it has worked really well. For its capacity, it’s not too heavy, and the battery life is impressive, even when used in cold weather. At under $30 while on sale, the value is excellent. Charging speed does depend on the adapter you use, but after testing different options, I found that it can definitely handle high-watt charging, which is a big plus. Overall, this is a reliable, well-performing power bank at a great price. I’m very happy with it and would recommend it to anyone needing a dependable backup battery. Read more
Battery is really impressive. Lasts really long and does not die quickly. This gives plenty of options and can work with multiple different heated jacket brands since it offers three different sizes that it receives. It can also just be used as a really large capacity portable charger or battery for mobile devices. It provides heat for hours for my Milwaukee heated gear even on the highest heat setting. This thing works really well and you can also check the battery percentage on the little screen it has. Read more
I was looking forward to using this battery pack, but I didn’t realize that heated jackets aren’t universal in their power requirements or connector types. This one didn’t match my heated motorcycle jacket, so I wasn’t able to use it for its intended purpose. The connections and voltage simply weren’t compatible. That said, the battery itself appears well-made, has plenty of capacity, and should work well with the right heated gear. I still plan to use it as a high-capacity power bank for charging my phone or keeping devices running during power outages. Just make sure to double-check the connector type and power specs for your specific jacket or vest before ordering. Read more
