A place to share practical, durable and quality made products that are made to last, with an emphasis on upcycled and sustainable products!

Guidelines:

Things that are well-made and durable (even if they won't last a lifetime) are A-Okay!

Unlike that other BIFL place, Home-made and DIY items are encouraged here, as long as some form of instruction is included in the body of the post.

Videos links are not allowed as post titles, but you may use them in a text post.

A limited amount of self-promotion is accepted, IF the item you are selling aligns with this criteria:

  1. The item must be made with sustainable or recycled materials.
  2. If electronic in some way, the item must be open-source.
  3. The item must be user-serviceable (if applicable).
  4. You cannot be a large corporation.
  5. The post must be clearly marked with a [Self Promotion] tag in your title.

This might be a lost cause, but I'm looking for small & medium (so max 1A and max 2.4A power draw) USB fans without a battery (corded power only) which will last more than 1 to 2 seasons even at a 90% duty cycle. USB fans are a common enough item that unusually good ones may exist, but it's really hard to find any amid the tsunami of cheap trash.

Yes I'm aware cheap DC motors don't last, I have my reasons for needing USB powered fans, please do not suggest fans which use AC power.

The most overbuilt option is probably this: https://www.noctua.at/en/products/nv-fs1

You can mix and match components because at it's heart it's just a PC fan in a custom frame.

Yeah, without a doubt this is going to be the best surviving fan you can get. USB to 12v if you need it to be USB powered.

If USB C is an option then 12V USB C PD cables are a thing.

Looks like USB PD 3.1 supports 28V

If you need a bigger fan then Geek Air sells a 12 inch camping fan. It has a battery but crucially it has a DC barrel jack for charging. I personally own one so I can tell you the charging brick has a 27V 1A output suspect a 28V input would work just fine. Or you could make your own charging circuit with a buck converter or something.

Its a solid fan. Not sure what your needs are but it's another option.

I bought it on the jungle website but the model number is CF1SEB if you want to buy it somewhere else.
