You mentioned it can run on 6 D cell batteries, so that would be 6 x 1.5 volts = 9 volts total. That suggests the fan is intended to run on just 9 volts, and that AC-to-DC adapter probably outputs 9 volts. The way you are powering from the cigarette adapter is 12 volts, essentially overpowering the fan motor and resulting in faster rotation of the fan, thus the higher watts drawn. I think this could eventually wear out the fan sooner. A simply electric motor will be more forgiving of this mismatch, but I wouldn’t do it to any valuable or sensitive electronics. For fire safety reasons I think I would stick to the AC-to-DC adapter and only push the fan at the intended 9 volts. Best of luck!

I have this same fan, as others have stated the AC plug puts out 9v... It is the exact same motor and blades as the fan that uses 8 D cell batteries (12v) they just use 6 to make it smaller.. I have my cabin wired totally for 12v solar and 2 of these fans in a window works awesome. 1 amp on high and .5 on low each, a std 20 inch box fan powered via 150w inverter pulls 4.3 amps. Ill stick with DC power.
If the fan draws 7 watts on 12 volt thats .58 amps. Take tje 110 divide by 7 its .068 amps. The power consumption is the same .watts are watts. .58 amps x by 12 is 7 watts. .068 x by 110 is 7 watts .current changes but the watts are the same😊
The AC adapter plug has an electrical resistor built into it where as your DC adapter does not. That's why your fan runs faster and pulls more watts from the power bank using the DC plug.
It actually is.. they use the same motor as in the fans that use 8 D cell batteries.. They use a std 550 sized motor with 1/8" shaft, you can try different motors for the RC rock crawlers and get different speeds if so inclined, 50 turn upto 100 turn motors are available. More turns the slower and less amps used.
@@BrianWatersOutdoors I think where its nesuringnthe power pulled isnt where it should be . Like say if the measuring is going on afterter the converting happens then yes ac will seem lower. And theres no converting for DC so its accurate. But if you measured like the amps pulled from the battery when the fan is running on ac vs dc I believe the dc will be pulling less. And also not to mention theres heat wasted with switching from ac to dc. Theres likely heat wasted as wure heats up for just straight dc too but I'd wager it's not as much so even less is getting to ac
First you want to be careful crossing AC and DC, but you got lucky here IF you didn't already know it was DC (aka wanting someone to comment the video lol). The plug on the fan is already DC. The AC adapter converts DC to AC. You kinda freaked me out when you just plugged that up like that lol

Thanks for the explanation! Makes sense now

Having both the AC and 12VDC options gives you two extra fan speeds. Nice to have those extra options depending on circumstances :)

Nate Howe has the only explanation that makes sense. 9 Volts DC fan running on 12 Volts DC makes it go faster and use more watts. Simple.
👍🏻👍🏻
Aren’t you over powering the fan directly on 12v? Hence faster speed? Verse the AC adapter conversion to ? Less then 12
Maybe🤷🏻♂️
How to modified the adapter using the cigarette charger?

If I used the 12 V cord I would run the fan on low. You could get one of those adjustable cig lighter plugs.
👍🏻👍🏻
Just viewed your video for first time. Curious what your 1 year review is? Love your content. Very informative.
Thanks. If you’re asking about the fan….I still use it 👍🏻 it’s held up just fine
@@BrianWatersOutdoors Tenergy 320 thoughts? Looking for budget friendly power similar to that.
@ericprince6672 gotcha. I think it’s one of the best budget lifepo4 power stations you can get. Also still using mine
The AC adapter plug has an electrical resistor built into it where as your DC adapter does not. That's why your fan runs faster and pulls more watts from the power bank using the DC plug.
Thanks Jarrod
No.. AC plug puts out 9v and the DC he has is straight 12v..
You get a full 12v and 10amps on DC. On AC you are being limited on Volts and or Amps.
Thanks Brad
I just got the same fan
The AC adapter is lower than 12v
👍🏻👍🏻 thanks
Im about to live in my truck, my dad passed 2 months ago and house is being sold off by the state, I need this setup
Contact a social worker. Somtimes the provide rent in the event of a parents passing. Some places also do debt forgiveness so you can keep the house
It's: No questions asked. Not: No problems asked.

Check the rating of the ac adapter,
👍🏻
Everyone assumed this was a 9v fan running overspeed at 12v DC. What if it is a 12v fan running under speed at 9v?
It actually is.. they use the same motor as in the fans that use 8 D cell batteries..

No its actually pulls more because its needing to convert the dc to ac. So you use more on ac

I need to buy from you! How much will you sell it for? I am serious!👍
Lol. What are you wanting?
The little generator you created.
She wants your generator down below.........🙄
you can hear the difference right off the bat with the fan
Yes, you can
