This powerful battery pack is amazing! I love the versatility of having USB, Type C, and DC outputs. Right out of the box, I used it to charge my phone on my way out the door, and it worked perfectly. When I got home, the battery level was at 86%, and using my laptop’s Type C charger, it took just 1 hour and 17 minutes to reach 100%. I also really like the clear display that shows the battery percentage, working current, and voltage, which you can toggle with the power button. The percentage sign flashes while it is charging, which I love because it makes it clear that it is actively charging. It is a little on the heavier side but with up to 13 hours of heating a heated vest I do not mind that at all as that is pretty impressive. For the price, it is an excellent choice for ensuring you have backup power on long days out whether you are hiking, camping, traveling, or just on the go. It is so versatile since it can charge your phone, power heated vests or pants, charge music devices or lamps, and countless other items that need power. One last note, the included manuals are unusually clear and well done. They are easy to read, answer common questions upfront, and seem impressively free of errors which is rare enough I thought I should mention. It’s clear some real thought went into them. All around a a quality product. Read more

I've used this on my heated jackets, vest, and bib with no issues. It seems like the battery lasts forever, and I can get through a week of using my jacket without getting below 40% battery. It takes a while to charge fully, but if you leave it overnight, it's guaranteed to be full by morning. It's a bit heavy, but it's a thick battery pack, so that's to be expected. It provides enough power to keep my heated clothing on and charge my phone to full a couple times, so no complaints here. Solid value for the price. Read more

Accurate capacity which is refreshing to see. The 7.4v port is directly connected to the battery without voltage conversion. This means the capacity test will show very close to the real battery's capacity without having losses through the buck/boost circuitry that USB requires. It also means the voltage at full charge is 8.4v and empty is around 5.6v. Most heated jackets operate off a port like this so they can get the most run time possible. I capacity tested this at a 1A draw on the 7.4v port. Rated: 16,000mAh @ 3.85v / 61.6Wh Actual: 15,756mAh @ 3.85v (7878mAh @ 7.7v) / 57.7Wh This is 98% of the rated capacity. In my opinion this basically meets the rated capacity since there is some variance in test equipment and connections. This pack charges at about 18-20w (3-4hr recharge). The heated jacket connector on this battery is 4mm, and it comes with adapters for 4mm to 3.8mm as well as 4mm to 3.5mm. This works well in my heated jacket and I've run a full charge/discharge cycle on it. It runs 6-8 hours on low pretty easily. Read more

I have been using this as a regular battery charger. It works at charging Samsung phones. It is capable of doing a fast charge but not more. It is surprisingly compact for the battery capacity. It has a DC voltage port where a heated vest would connect to. The build is sturdy. The USB port hold tightly on the cord. The weight is about what you expect from a battery this size it's a good value if you have a vest and need to charge your phone. Otherwise dedicated chargers are better. I love the percentage counter. I think all batteries should have this. Makes it easier to determine how much charge is left and how full it is when being charged. Read more

The media could not be loaded. Let me tell you something, my electric vest is a lifesaver. I'm not a fan of the cold, so to me... it's a must-have. Sadly, it came with a puny, generic battery that only lasted about 3 hours. And that was on low. 𝗧𝗵𝗶𝘀 𝗶𝘀𝗻'𝘁 𝘆𝗼𝘂𝗿 𝘀𝘁𝗮𝗻𝗱𝗮𝗿𝗱 𝗽𝗼𝘄𝗲𝗿𝗯𝗮𝗻𝗸, 𝘁𝗵𝗼𝘂𝗴𝗵 𝗶𝘁 𝗰𝗮𝗻 𝗯𝗲 𝘂𝘀𝗲𝗱 𝗮𝘀 𝗼𝗻𝗲. The most notable difference being that this one has a DC port along side the USB ports. Additionally, it also comes with two different DC plug adapters which improves it's overall functionality. Another difference being that this one cranks out a bit more power than standard banks. 𝗧𝗵𝗲 𝗵𝗼𝘂𝘀𝗶𝗻𝗴 𝗶𝘀 𝗰𝗼𝗻𝘀𝘁𝗿𝘂𝗰𝘁𝗲𝗱 𝗽𝗿𝗲𝘁𝘁𝘆 𝘀𝘁𝘂𝗿𝗱𝘆. Invoking a solid sense of confidence that it will survive the rumbles and tumbles of being in your bag or pocket. Just try not to drop it too many times. With its 𝟭𝟲𝟬𝟬𝟬𝗺𝗔𝗵 𝗯𝗮𝘁𝘁𝗲𝗿𝘆, 𝘆𝗼𝘂 𝗰𝗮𝗻 𝗲𝘅𝗽𝗲𝗰𝘁 𝗶𝘁 𝘁𝗼 𝘀𝗲𝗿𝘃𝗲 𝘆𝗼𝘂 𝘄𝗲𝗹𝗹 in not only powering your heated garments that will provide you with the warmies, but also to faithfully charge your other devices if need be.

My vest has a 'regulator' in it that shifts from high to medium to low and then back to high, etc in order to prevent overheating. However, 𝗶𝘁𝘀 𝗰𝗵𝗮𝗿𝗴𝗲 𝘁𝗶𝗺𝗲 𝘀𝗵𝗼𝘂𝗹𝗱 𝗿𝗲𝗺𝗮𝗶𝗻 𝗽𝗿𝗲𝘁𝘁𝘆 𝗰𝗼𝗻𝘀𝗶𝘀𝘁𝗲𝗻𝘁.

You just need to plan intelligently to always make sure that it's charged and ready to go. 𝗔𝗻𝗼𝘁𝗵𝗲𝗿 𝘀𝗹𝗶𝗴𝗵𝘁 𝗱𝗿𝗮𝘄𝗯𝗮𝗰𝗸 𝗶𝘀 𝗶𝘁'𝘀 𝘄𝗲𝗶𝗴𝗵𝘁. Once again, because it is a larger battery pack, it does have a bit more weight to it compared to others. 𝗕𝘂𝘁, 𝘁𝗼 𝗯𝗲 𝗵𝗼𝗻𝗲𝘀𝘁, 𝗶𝘁 𝘄𝗮𝘀 𝗻𝗲𝗴𝗹𝗶𝗴𝗶𝗯𝗹𝗲 to me. After about 15 minutes of wearing my heated vest, I really didn't notice it. So, I wouldn't worry about that at all. Final Feel: Everyone these days should have at least one powerbank. And this product is a proof positive that there really is no excuse anymore to not have one.
