I have two of these. The internal batteries suck so I removed them and just use a USB power pack.

I noticed mine was warm while my TV was off when I went to check it.

Testing now but I don't have anything to reliably measure temps.

I might use my USB fan on it if I notice it getting hot. I have one of these that's pretty quiet and portable:

Ok, so here's the items I often pack, and they have served me well so far:

[Redcross Flashlight] (https://www.amazon.com/dp/B003BYROUQ/ref=cm_sw_r_other_apa_2SSlxbRHB73T6) that handcranks to charge itself and small devices. Because of this, it's my top suggestion. I've used it to recharge my Kobo ereader, [my headset] (https://www.amazon.com/dp/B00LAF23VI/ref=cm_sw_r_cp_apa_g3Qpxb5M3BKJP) (which I've been very happy with, and will order again if/when it breaks), and a small Bluetooth speaker for playing music in my room. I tried to charge my smartphone with the flashlight crank, but it's not advisable, it will take forever.

Other lighting includes [a headlamp] (https://www.amazon.com/dp/B015R1I6AM/ref=cm_sw_r_other_apa_b2Slxb0QVR92C) and when fighting the heat, I found this fan. For those into vaping, I suggest looking at Vapium Summit, I gave that as a gift, and it's nice for the price.

I tried to find a real sturdy USB hub, but just went with a cheap one with decent reviews.

And finally my portable powerhouse for when there's no outlets nearby: Orange Joos and i will agree that any solar panel will do, but this has a built in battery that holds a charge. It's not flimsy, but also not ultralight. I'm happy with it.

I've said this here several times because it is the one thing that has been the most helpful of anything to me. It only solves one problem, but it's a big one for me and will be for you. Get a small desk fan like This. It's a few bucks more but I have this one. It's rechargeable via USB. I keep it plugged in at my main desk most of the time. I have 2 setups at 90 degrees on my desk and I just turn it to blow on whichever one I'm using. Then, since it's battery operated, I can unplug it and point it at my hands or paper or project, whatever I'm doing anywhere else. I've even set it up to point at my hands when I'm using my phone. I work from home most of the time, but when I have to go to the office, its small enough to throw in my laptop bag and the battery will last the whole day on low (which is usually enough to keep me completely dry. My hands do get cold often, but it's worth it and it tends to cool my whole body. I'm grateful to work from home because most days I have to have (1) the ceiling fan on (2) socks on (3) my desk fan (4) a space heater (5) a hoodie and (6) a blanket...which has to be cotton because we all know what happens with a fuzzy blanket.

If you don't already, get some clinical strength deodorant. It's worth every extra penny to me.

As for the other options, you'll probably just have to try them one by one, trial & error starting at the easiest, least costly and least invasive. You can order glyco online (oral and wipes) and iontophoresis without a doctor. If one of those doesn't do it, see a doctor. If that doctor tries to tell you it's not a big deal, something you'll grow out of, or just doesn't seem to get it (it's pretty common), find another doctor. sweathelp.org Has a lot of resources and suggestions and explains all of the treatments. So far, the only thing that has worked for me is Botox. But it is expensive if you don't have insurance that will cover it. You may have to fill out some forms to ask them to. Botox also has some mild side effects that cause some temporary weakness in your hands. Depending on your job, that's something important to consider. It's also painful, but for me, only during injections.

If you browse around this sub, there is some good info on special tshirts and socks that people tend to find are helpful, especially for that underarm sweat. Wear black when you can, most of us do. If you're going somewhere you know you'll have to shake hands, put a papertowel in each pocket. If appropriate, it's better to go in for the fist bump if you can.

You may never be cured, but there are options and one may work really great for you. And when you find it, you'll know and you'll be equipped to support & help your kids through it (if you decide on them and) if they even get it. I'm pretty sure one of mine did, although not yet as bad as me. The other didn't at all. I've dealt with it for 42 years. It's still exhausting and enraging when I'm not full of Botox, but it does get a little easier as you learn that people don't notice as often as you think. I've said this before too. If someone is really put off and grossed out by it, they're probably not someone you want in your life or who's opinion should even matter to you. It's impossible to ignore, but don't let it define you.

I really like this fan.

The thing is you kind of have to make the jump to 18650 rechargeable batteries. I am a flashlight junkie so that helped when I decided to buy this fan. The battery that came with it is "OK" but there are better one out there. R/flashlights has a ton of info on 18650 batteries. 18650 batteries can also be used as power banks for charging your phone. I use the charger that came with this headlamp as a travel charger/power bank. I'm sure you can find it by itself. Make sure to buy quality batteries though.

Good luck!

I got this fan recently and it's perfect for camping. Three speeds plus a night light LED function. Charges via USB and lasts about 8hr on low, which is a decent breeze, I rarely find I need to crank it up more.

I put a canopy over my tent too. Getting Usb Fans with battery packs to create some airflow. Open your doors or any vents.

I use a rosin bag as well as one of these (different brand, but same Chinese generic product). USB rechargeable, but it takes the same batteries as I have laying everywhere for ecigarettes.
