Thank you so much for watching my 3rd video I've uploaded this week rebooting the channel after a long break. This USB fan is one of my favorite cheap gadgets that really help's me out and I'm glad I could share it with you. I hope you're enjoying the new content and you get a chance to come to watch me LIVE on Twitch during the week with the link in video description or come hang out on Discord. If you have any questions about the fans just ask them below or research them with the link also in the video description.

I have the desktop version of these, they are great. I used to work in a call center and they were perfect because they never picked up on the phone. The desktop ones have a variable speed dial too. Well worth the money.

So, a guy on Amazon says that these fans use ~0.9 watt-hours of juice. Given that the Razer Blade Pro has a 70 Wh battery, assuming nothing else is drawing power, it can run the fan for ~77.7 hours. So, not quite years, but still a decently long time.

@@Cheese_1337 Yes there will be small loses due to internal resistance and to other component. Probably closer to 140-150 hours with loses. But this also does not account for any battery degradation.

According to amazon.de's product page: 5 V (USB standard voltage) * 0.2 A = 1 W. The 30 Ah battery back has capacity of 450 Wh (5 V output). So, the fan would last 450 hours under optimal conditions and the smaller one could power the fan for about 25 hours. It's probably a little less than 450 or 25 hours, due to losses in voltage conversion etc. (18650 cells have nominal voltage of 3.6 V and max. about 4 to 4.2 V)

Alright, the Razer Blade Pro has either a 70 or 99 Wh battery. An Amazon reviewer measured the current used as around 170 mA at 5 V, which totals to 0,85 W. Say we have an efficiency of 90% for the buck converter in the laptop, this gives us a 63 or 89,1 Wh of effective capacity at 5 V. That means that, depending on the model and given that the fan would be the only thing run by the laptop, you could expect about 74 or 105 hours of continuous fan-running off the Blade.

@aarorasilainen

For the 30 000 mAh battery: they are rated at the nominal voltage of 3,7 V giving a total maximum capacity of 111 Wh. Say, again, we have a 90% efficiency in the boost converter, we have an effective capacity of 99,9 Wh, giving us an estimated runtime of about 117 and a half hours.

I hate to admit I've gained about 25lb back after Keto caused some other medical issues and I'm suffering from a lot of down time related to chronic pain. Doctors are trying to figure me out so I can get back to doing what I love!

These fans are great, I have 8 all round the house and have been using them for 5 years now :).

had one of those since like 2014 or 15, no noticable degration over time and the bending part is as stiff as ever (ladys). i used them to cool my room, they get a good airflow in a room if placed stategigly (one of those). its not as quiet as a regular pc fan, but more quiet than any other usb fan i ever had, they are made by arctic and u can hear and feel that. at the moment i plug it in my mainboard whenever i load into a game to cool the back of my gfx card. i think they take 300ma, my powerbank with 20000mah ran it 34-38h. my 85yo grandma bought one and a powerbank when i showed it to her, and in the summer she takes it everywhere she goes.

Wow...how did I not think of this. I've needed a fan at work for the longest time and I sit fairly close to the computer so this would be perfect with spring/summer right around the corner.

I bought 2 like over a year ago, and they are still amazing.

Good to have you back man

The Fan runs on 5V .2A so 1Watt. The Razer Blade Pro has either a 70Wh or 99 Wh battery Depending on the configuration of the laptop and battery health, it can run for 3-4 days

I actually bought two of theses because of one of your video talking about them and put them on my modem and router. I use to have an issue where my internet would just randomly drop and would require me to restart my whole network, I stuck a USB extension to my router and plugged a fan into it to cool my modem, then stuck another fan in to cool my router things are great. tempted to get more to cool my consoles seeing they could probably use all the extra help they can get.

Thank you for this so much. I have a four year old gaming laptop that I need to have a desk fan blowing over to keep cool and I think this would be perfect to keep it cool since I’ve got an extra USB port on the side.

I cracked my brain when you immitated a cheap pc fan at 10:51

if you put enough fans on that laptop, u might be able to turn it into a drone...

According to producer specification, fan consumes 200 mA per hour. This means, 10000mAh power bank will theoretically power it about 50 hour. In real life i will count with 45hours.

the fan consumes 5v 0.2A (1Wh), Razer Blade Pro says it has a battery that outputs 99Wh, so, with full battery can run it for 99 hours

Love seeing you doing videos again bud!

Give or take a 30k mAh should keep it running about 6-10 days. This is dependent strongly on the efficiency and age of the battery pack, the power leakage of pack and fan and the resistance of the wiring used on the fan and battery pack. The fan tech sheet says it runs on 0.2 amps but that is the rating of just motor. My calculations are based on the efficiency of the best and worst power pack I have data sheets on. On a brand new pack with high efficiency it could be as high as 45 days but that would be a marginal case. It is safe to say an average of 6-10 days non-stop.

Arctic fans are great! I have used them in my last couple builds. Good airflow, silent and affordable

Got one of these after this video as my laptops keyboard gets extremely hot when running intense games, now it not only stays cool, but actually cold to the touch, much better than typing with sweaty hands on a hot keyboard. Edit: also the fans are just as quiet as you said they are, I had fans like this before that made noise so I figured I knew it had to make more noise than you made them out to, but no, these are totally silent, so much so that it is almost absurd.

I use them for the same reason :) Except I use generic versions that cost like $1 each. Maybe they wont last as long as the Arctic branded version and their arms aren't as good quality.

I'd also advice people who want one for silently cool your face in your desk or booth to check boothjunkie's video on a usb fan (a more stationary one) that's dead silent for the amount of wind it blows, great for streamers or in general audio sensitive situations.

@Cristian I just want to share my humble opinion just as an information. $10 is not that cheap? It's definitely more expensive outside of the U.S. Life in the U.S. is so easy and U.S. citizens are still complaining about the prices. Try to buy something in other countries as a citizen of that countries - you will be surprised. The ratio of the purchasing power of earned money to the price of goods is most favorable in the U.S.

Assuming you have the top model Razer blade pro, with a 99Wh battery and the fan drawing 0.2 A @ 5 V, it will last 99 hours (4.1 days). Not quite a month, but pretty long

Been using these for the back of my LED TVs for years, good to know im not the only one who thought it was a good cooling solution, cant rate them highly enough

I have one of these and they're great. Using it through a USB power meter, it uses around 1 Watt, so whatever the W/h rating, that many hours. For that particular laptop, it has a 99Wh battery, so 99 hours. It does fluctuate randomly from 1W to 2W (on my meter) very briefly, but for simplicity sake, lets say 1W/h for this fan.

Cool! Thanks for sharing! Will get some.

Barnacules glad to have you back bud.

Going by the rated draw of 0.2 amps at 5v from the fan and given the razer blade pro has a 99wh battery at 11.4 volts, In a perfect world it should run for 98ish hours if nothing else is drawing power. Realistically with the rest of the system and inefficiencies in the voltage regulation I would guess significantly less time. 18-20 hours would be my guess .

in alaska they would be probably worth, because they could help move the warm air from stove :D

If you live in a humid location you could put one under your cabinets angled so that they move the air from the back so that you don't get mold on your walls behind the cabinets.

So glad you’re back!!!!

Assuming each of those fans draw the advertised 0.2 amps, it'll (theoretically) take 75 hours for two of those to drain down that big battery pack, and 25 hours for the tiny battery on one fan, may have to subtract a few hours from power conversion losses.

To save the boring math and reading, POWER BANK = 7.4 days and LAPTOP = 3.4 days (if my math is correct) On the amazon page, one of the questions someone asked was how much power do the fans use. Some responded saying they measured about 168.5 mah which I assume for the power bank being a 30,000 mah bank, 30,000/168.5 = 178 hours or 7.4 days. As for the Razer Laptop, it has a 70wh battery. Using an online calculator and seeing from the amazon post that it draws 5.02v, that is about 13944 mah or 13944/168.5 =82.8 hours or 3.4 days. That calculation doesn't seem to add up in my opinion. I would assume the laptop would have a much larger battery then the power bank. So if I did everything correctly, 7.4 days with the power bank and 3.4 days with the laptop.
