OCOOPA Hand Warmers Rechargeable, 7800mAh Long-Lasting Heating Electronic Hand Warmer, Battery Powered Great for Camping, Hunting, Warm Gift, Power Plus, 1-Pack

I am using Category 4 cable). Up front in order of bottom line It would be a pleasure to buy these again. A very good job is done by them! 1) How many of these items do I own I have four sets from OCOOPA (2 each). Three pairs of the 5200mAh are in my collection (6 purchases) and one pair of the 7800mAh is in my collection A pair of devices cannot be purchased at the same time. 2) Which of the following should you purchase, It was only until I bought the 7800mah version that I became aware it existed, or I would have chosen them straight away. These are great for watching football while it is cold outside. It is even more useful if your kids participate in sports to buy them a pair of mittens, not gloves, and let them use two of these to keep their hands warm between runs. 3) Lessons learned when it comes to charging I think it's a good idea to buy a USB stick for yourself so do yourself a favor. Plug a C cable into these hand warmers to charge them. Providing a charging cable with these hand warmers is a big issue for me. the micro USB cable included with the device. An USB tester I have is available to me. Battery charges at a voltage of 5 volts and has a current of about 1 amp. With a USB port, you will receive 6 Amps When the device is charged with a Micro USB cable, the battery is charged to zero. This is 7amps! I think it will take two if I am doing my math correctly. A Micro USB charger requires 2 times more time to charge. It is only necessary for OOOPA to supply a USB cable In the package, there is a C function. Size The 7800mAh battery is about 20% wider than the 5200mAh version, with the most noticeable difference being the thickness. Charge other devices

5) Take out credits and use them It is possible to charge other devices from the USB port of the 7800 You can either use USB Type C or USB Type A As with any USB battery pack, this one has an A(normal size plug). The micro USB port on my computer does not have any cables that could be used to charge another device.

6) Any other information

There is one minor disadvantage, the bags that come with the kit. It wasn't until last year that I realized how big my bags were with my first 5200 model purchase. There is a bag provided with both sizes of hand warmers that is identical for the 2019 version. A bag provided with the 7800 hand warmer does not fit, and the bag on the 5200 is too small. In combination with the larger hand warmer, I use the old bags from my older set of 5200s. Even if they aren't as good as they were before, I would still buy Lastly, I would like to share the following The answer is yes, I would definitely buy them A very good job is done by them! Their temperatures were set to the lowest possible setting. Although it takes longer for it to warm up, When they get to temperature, the recirculating motors will slow down, but your hands will remain perfectly (For me) At the highest temp the battery charge is used up much faster, and there's discomfort when holding it. We like the high-heat setting because it keeps our kids warm.

There is no such thing as a perfect life! The smaller versions of these handwarmers are fun to play with (it's easier to fit in a pocket), but the biggest con to the smaller version is that the USB port is a separate, small (like 1/2 inch square) adapter that is warmer has a USB port built right into it, which means you don't need to worry about having an adapter around. This hand warmer isn't small, but it's quite easy to manage and hold in one hand, store in a coat pocket, etc.

All in all, these rechargeable hand warmers are fantastic. This device is convenient as it allows you to adjust the amount of heat and lasts for about two hours based on how high you turn the heat up, how long you use the battery charger, etc. I am very satisfied.

My car is now equipped with this one. Winter is the best time to use it, as it warms my hands before starting my car. You can also use it to store extra power. I wonder if someone thought it was too small because it's not big. Three different temperature levels are on the board, and I'm fine with the lowest one. During testing, I found that it was sufficient for charging one iPhone XS Max.

It is far superior to any other I have used. The warmer has a very comfortable feel and gets quite warm/hot. It is a must for anyone who suffers from "cold hands" or Raynauds. In any case, it does not last an entire 8-month period A description states that the job will last 12 hours. With a fully charged battery, I typically get about 5 hours of use. My wish would be to have it Another major improvement would be if this warmer could be attached to a wrist strap, like many other warmers do. It is quite heavy, and I have to put it in my pockets when I need to use my hands. By using a strap, this would be prevented. The carrying pouch would serve as a replacement for the A pouch that comes with this product is useless, however. off, the warmer is a bright blue color and does not go with the black one Besides with the color standing out too much in my office, I could not put this bag to use since the strap came loose before I could put it to use. There was a problem with how it was tied on. It has been a pleasure using this warmer. It's annoying to not have a strap and to have a short battery life. I would give it five stars if it had a strap at the very least.

It takes hours to charge the battery up, and its battery life appears to be short. The charging feature cannot be used while it's charging, and there is no way to attach a string to it so it wouldn't fall. The only reason I gave it one star was that I've only tried it a few times, and one side wouldn't heat up at all, so when I tried using it yesterday, one side was so cold that I couldn't hold it without getting cold. The price was also more than last month, which is strange since it was purchased a month earlier. The price has been lowered by $7. My money is gone, and I'd like it.
