Got a baking hit trip to France coming up.

Anyone got any advice on good rechargeable fans and fans to avoid? Any outside the carp market?

Get yourself a silvered tarp, bungees and camo cord and set up an open sided sun shelter.
And plenty of mozzie repellent.

I went to Rainbow and the hottest heatwave they had had in 40 years happened !!
40c plus temps only dropping to mid 30s at night !!
I drove to the truckstop motorway services and bought one of those 8 inch blue truck fans
I had a folding 50 watt solar panel with me and found it ran perfectly directly off the solar panel
it was a proper life saver
so I reckon ANY of these fans will fun off a solar panel directly

Ive got a baby stroller fan. It takes 18650 li ion batteries (you can leave them in and charge them) it last about 12 hours. I think it was £20 of Amazon.

I have the Trakker usb fan that has a pad behind it for adding citronella oil, it runs off of my 20w solar panel no problem at all. Through the night, if needed, will run off a normal phone power bank too.

This is spot on, a open sided shelter (might have to get a bit bear grills and create something with ropes and poles but a sheet of tarp is deffo the way to go. Shade from the sun is key, a fan is good to noone, refardless how powerful it is....blowing warm air around a bivvy.

Bought this one from Amazon earlier in the week. Took it to work and put it on in my train cab (our old trains have no air con!), it was a lifesaver. 2nd speed level was enough, I had it on for 4.5 hours without the battery running out so I don't know how long it actually lasts. Flexible arms so can be hung off brolly ribs etc. 20% off too.

Is there any difference between the Trakker and the Nash one apart from the colour and roughly £1.50 difference between the prices?

They look identical and more than likely are. My guess you could probably find that exact fan without the carpy brand stamped on for a fraction of those prices.....

A very quick search on amazon and I found the identical fan for 15 quid.

clearly you havent fished in extreme heat where the only way to stop the sweat running in your eyes no matter where you stood or sat was to have a fan blowing on you
look around the world any hot countries all have fans every where ceilings etc

RIGHT THIS MIN my ceiling fan light in my living room is going keeping me lovely and comfortable big smile

Except it's £16 plus 3 quid postage lol

I only paid 20 quid for my Trakker and there were a couple cheaper places but I went with prime delivery instead

But yes, there will be un branded that will be the same, if no rush then i suspect cheaper on Ali or similar

OK that was a daft comment, I agree fan's do make a difference. I have fished in hot climates on the odd occasion and worked in even hotter ones for months on end. So yes I have been in extremely hot climates. Certainly worth setting up a shelter tho....or at least having the set up to do so because if you end up in a swim with no tree cover...... you'll roast in a bivvy, even with vents and a fan.

I've got the Trakker one and very happy with it.

Last week Morrisons were selling USB fans for £4 so I thought why not. It is s.hit. Soft blades and you need to be less than 6" away to feel it.

It's air movement that has the cooling effect. Stick you head out of a car window doing 60, when it's 80+ degrees outside, bet it feels cool.

Genuinely cannot see the point in having a remote for a fan that to be effective needs to be within arms reach. Are we just getting lazy?

Could well be easier yeah, or even a sideless gazebo if room allows.

The absolute worse place you can be in the heat of the day is sat in your bivvy, you are literally sat in an oven.

Basically some form of sideless shelter, have the shelter as high up as possible. Or better still pick a swim that's got a tree's behind you and will block out the sun for most of the day.

We have all fished on those days where one half of the lakes anglers are all wearing hoodys and fleeces (tree cover) and the over half sat in shorts and shirts off in the heat of the sun.

From my limited POV I think useless is very close to the truth.

Fans can't invent cold air, they are a short term fix to keep moisture away. Fans in houses and especially ceiling fans can have some impact with open windows, but when the air temperatures are such, they are not magical enough to find new cooler air, or provide enough power to mimic sticking your head out of a car window.

The old days in cars they were shocking but that is how the science of fans is, they circulate air so only cool in enclosed spaces for a very limited time. In a car (pre air con) windows down was the only way and when stationary it was hotter inside than out, even with the fan on.they may be better than nothing but ultimately you need to find shade and paddle to really lower body temperature or have something cold behind the fan for it to recycle warm air into cold.

The cooling effect of a fan in a warm room comes from moving air over your sweaty skin. The moving air (warm or cold) speeds up the evaporation of the sweat, allowing your body to cool itself more effectively.

Think I've said it before on a thread somewhere but a nice little tip that works when its scorching, when I was fishing at Iktus for a bit in the height of summer and daytime temps were over 40 degrees, the Spanish anglers on the lake were prepared and brought rugs with them to throw over their bivvies, every other hour or so the would douse the the rug in the lake water (which although warm was a lot cooler than air temps and scorching sunlight) and then throw it over the top of their bivvies, whilst the water was warm it was a lot cooler than the bivvy material it achieved two things it cooled the bivvy material down as well as making it darker and more shaded inside, I was amazed at how much cooler it was in their bivvy as opposed to mine which was like a proverbial sweat box.

After reading your message about the new Rechargeable version I thought I may get one. Been looking at them and think I won't bother as the new one seems to no longer have the pad at the back for citronella oil etc.looks like this is where the battery now is. Also using micro usb to recharge is stupid with everything going usb-c

Think I'll stick to just running off of solar or powerbank, will get far more runtime from a powerbank too..

>>>>Fans can't invent cold air<<<<

Completely incorrect, fans blow cold air. Why, because the blades on the fan compress the air slightly and compressed air is cool. Uncompressed air is warm. So basically, the faster a fan is going and with the right shape blades blowing air out and compressing it, the air will feel cooler. Blast compressed air onto an object and it will freeze it with ice forming on it. Why do you think on a hot day out of the wind it is hot, but step out into the wind, its cooler, the wind is blowing gusts of compressed air. Basic physics.

Try it for yourself, blow on your arm with "pursed" lips, your breath will feel cool, the blow on your arm with mouth wide open, your breath will feel hot.

I suggest you Google it and you will also find that ceiling fans do work, simply because they blow compressed air downwards.

Perhaps you should have spent more time at school than "twagging" and going fishing.

Throwing water over a bivvy does work well, I have done it for years, as the water evaporates, it removes the latent heat from inside the bivvy. I also use the method to help keep my food cold on a hot day, just wrap my cooler bag in a damp tea towel, place it in the shade and it helps remove any heat from inside, just like my parents used to keep milk and meat cool etc in the pantry, just lay a sheet of damp muslin over it.

But, these days, usually in the Summer, I just take an ordinary fishing umbrella and sit outside of the bivvy under it and find that cool enough during the daytime.

No they don't cool air, they blow air around, the fan makes it easier for the air to evaporate sweat from your skin, which is how you eliminate body heat.

If you were in a sealed room with a fan on it would actually increase them temperature.

So to get any real benefit you need to be sweating a fair bit.

The only way a fan blows cold air is if its refrigerated (air con)

Here we go, I knew it would happen if I posted what I did, carp anglers know best and rewrite the books of physics.

A fan in a sealed room may warm the air up, but that is the affect of heat coming from the motor, not the fan itself. The air coming from the fan would be cooler than the ambient temperature of the room.

Blow on your arm when you are not sweating, it will still feel cool but by your logic, you have to be sweating.

Sweat does not need an air flow to evaporate, it takes the heat from your body to do that and makes it cooler. That is how the human body works. An air flow only assists but is not necessary.

Our lass on a night when in bed and its very hot, turns the fan on to keep cool, but she is not sweating, and also the room does not either get warmer either because the fan is on and the window is open, by your logic once again, this should not happen.

When you burn your finger etc, you blow on it to cool it down, once again, your finger is not sweating, but you get a cooling affect.

Explain to the World by your logic, that a radiator fan in a car does not work because they do not blow cool air but it is because the radiator is sweating and the air being blown over it helps it to evaporate and hence cool the water down.

Ive got a remote for the two meaco fans i bought last wk for our bedroom and my youngest daughters bedroom much easier than getting out of bed to turn it off. Lazy yes but why get out of bed when you dont need to. There no good for a bivvy but they defo dont blow hot air around. The bedroom was really cold had to turn it off and get under the quilt, best thing ive bought in years.

I'm not a carp angler myself or whatever that is in reference / stereotype to ?

What level of evaporation are we measuring ?
It's just disturbed air hitting your body - you are actually not cooling down.

Blowing on a burn lol, all you do is distract you brain by the blowing effect.
I just stick the burn under the tap myself mate that's basic first aid.

Air will heat up when compressed, particularly if done quickly, but hardly applicable to bivvy fans.
The cooling effect of air passing over a hotter object is probably due to convection, the hotter air in contact with a body replaced by slightly cooler air, drawing heat from the body.
Car fans nearly always suck the air through the radiator, rather than blowing it. The ambient air being drawn through is always cooler than the 95-100C engine coolant temperature when an electric fan would kick in.

If your capable of doing a simple experiment, stick a thermometer in front of a proper fan, not one of these "Mickey Mouse" things, and oddly enough, you will see that the temperature will drop a few degrees.

Now try explaining to the World, that it s because the thermometer is sweating, or its because its the effect of "disturbed air" because a thermometer is incapable of sweating or even has senses to detect "disturbed" air.

Or could it be that by the law of physics "compressed air is cooler than uncompressed air?

No matter how slightly the air is compressed by the fan blades, it will be cooler than the surrounding air.

Oh, and also by your logic, the temperature recorded by the thermometer should be rising because of the fan?

Let's put some context on this discussion..

In a bivvy so it's going to be a USB fan receiving a maximum of 500mA hardly going to be creating the necessary blow to cool a bivvy now in the peak of summer
It's the same feeling of blowing on your finger..

Now sticking a wet towel over your bivvy that's going to have a greater effect that'll I'll agree with 👍🏼

BUT Cmon stop all this argumentative bollix ??
THE FACT IS the post is about fans >>>>>>NOT IF YOU THINK THEY WORK OR NOT ?

anyone who thinks that sitting in front a fan doesn't cool you down ? is an utter fool ! I spent a couple of months in the Philippines and trust me it is tropical and a fan is essential
who gives a toss if you dont think it does scroll on by stop boring people and ruining a good thread

so lets keep the thread to recommending fans NOT ALL THE BORING ****S ARGUING ABOUT BOLLIX
