Price was a big factor in the first two brands i tried. One of these, the Hot Pod ( https://smile.amazon.com/HotPod-Rechargeable-Pocket-Warmer-Sleeve/dp/B00I4OFGZ8/ref=redir_mobile_desktop?_encoding=UTF8&psc=1&ref=ppx_pop_dt_b_pd_title ) was, at the time, the least expensive. It was not a good product, lasting only about an hour. I never use it. The next one i bought, Baisidai, ( https://smile.amazon.com/Baisidai-5000Mah-Portable-Electric-Rechargeable/dp/B01MYNLG0Q/ref=redir_mobile_desktop?_encoding=UTF8&ref=ppx_pop_dt_b_pd_title&th=1 ) was a big improvement and I ended up buying several. However, they only last a maximum of three hours - at the lowest setting - and take 6 -10 hours to recharge. I then tried the Pisen (https://smile.amazon.com/PISEN-Rechargeable-Double-Side-Handwarmer-Gift-Giving/dp/B06XP2BDTY/ref=redir_mobile_desktop?_encoding=UTF8&psc=1&ref=ppx_pop_dt_b_pd_title ) which lasts a good 6-8 hours and has an automatic shut- off. It needs to charge overnight, so I'm not certain of the exact time, but approximately 8 hours. It was more than twice the price of the Baisidai but a comparatively good value. However, it heats very slowly and has only one heat setting. It is also awkwardly shaped and too large for my hand to hold comfortably.Then I found this one! Two days after I bought it, I ordered another. It heats quickly, lasts a long time, recharges quickly and, in spite of the larger size is comfortable to hold. It's less expensive than the Pisen as well. It actually lives up to the description and I highly recommend it. ### ⭐⭐⭐⭐⭐ Perfect for my unusual need *by A***F on Reviewed in the United States on November 18, 2018* These warmers have been great so far for me, and if anything changes I will update my review to reflect that. My use case is completely different that the majority of people who will buy these warmers/power banks. I live in a very cold area. Its the middle of November, and it was between 10-25 degrees all day long yesterday. On top of that, I work at a high security facility and am strictly forbidden to bring my phone inside. I also work as a nurse, and we are chronically short staffed. Because of this, it is a very regular occurrence for my phone to have to sit in my car in freezing temps for 16-17 hours at a time. I was tired of having the temps kill my battery, not to mention putting undue stress on an expensive piece of hardware that I want to last a few years if possible. These hand warmers are the perfect solution. I purchased 2 of them to try to give myself enough coverage for the entire 17 hour work day. I am using these inside an insulated canister that I had left over from an old Zojirushi bento set that I have not used in a few years. I just stuff them all inside, turn one on, and it keeps my phone warm enough where I don't have any battery drain and the power button still feels clicky instead of the solid, immovable mess it would be before. It doesn't make my phone hot to the touch, more like room temp, which is exactly what I was looking for. I was concerned that there was potential for condensation to build up inside the sealed canister and do more damage to my phone, but I have not noticed any moisture at all. Just incase, and to add a little more insulation, I just wrap the warmer and my phone in separate washcloths. Couldn't be easier. I keep the second one inside of the canister as well in the included felt bag, just so it doesn't have to be exposed to the cold. Yesterday, with temps from 10-25 degrees, I turned the first one on and it ran continuously for 8 hours on the lowest setting with no issues. I am not sure how much battery was left, but there was still one light that would turn on to indicate charge, so I guess between 1-33%??? If I had to guess, I would say it was probably about 10% leftover. Then, in between shifts, I just swapped the one in the bag with the one in the washcloth. The second one had pretty much the exact same output as the first. So these give me the coverage that I need to keep my phone at the perfect temp for my entire ridiculously long work day. The real test will be if I can get the same results in January when it is regularly below 0 degrees for the entire day. Only time will tell, but if I don't update this review assume that it is working well. If I had to have a negative to say about these warmers, it would be that they do seem to charge a bit slow. However, I was using an old charging plug that came with super cheap 7 year old LG phones (not smart phones, just garbage). With these chargers it took about 5 hours to top off the warmers, but since that is about as long as I have at home between these shifts it should suit my needs. I am going to look into cheap quick chargers and see if they help with the speed though, just to be safe. I can not speak to how well they work as power banks, as this is not my intended use and they will never be used like that. I really hope these things last... ### ⭐⭐⭐⭐⭐ Excellent cosmetics, if it lasts, will make winter much more bearable in my cold office. *by P***R on Reviewed in the United States on December 29, 2017* The exterior craftsmanship is excellent. I cannot predict if this item will last a long time. It took a full charge in about 5 hours. When I unplugged it and turned it on, it warmed in seconds. If it lasts, this will make my workplace much more bearable during the winter. Follow-up-- I decided to give it a try this last few weeks at the end of summer. At my work, the air conditioner dumps all of the cold air for the building above my desk. While everyone else swelters on summer days, I'm freezing. I put one of these in my back pants pocket, and one in my shirt pocket, and I'm warm enough to work in comfort. Also, I prefer this particular unit for two reasons: 1 The battery is bigger than most, and 2 The on/off button is flush so it is less likely to be pressed accidentally. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/20879310-threeleaf-rechargeable-hand-warmer-7800mah-electronic-portable-instant-heating-usb](https://www.desertcart.tn/products/20879310-threeleaf-rechargeable-hand-warmer-7800mah-electronic-portable-instant-heating-usb) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-15*
