Description

Fixing tools blindfolded, episode 41 (163k likes): ‘whatever you want to watch, I’ll make it’ — a 9600 power bank from a 66W fast-charge kit (own nickel strip, no fish paper included so something else fills in, cushioning first), charge / discharge test, done, ‘not bad looking, sis, you get a discount’; then a chainsaw chain swap, a drill that won’t turn with a bad wire snipped back, a special tool for taking a blade off; 7466 comments: the Douyin logistics organizations list, a petition of ten thousand to see the tree at the door, requests for the welder link

I’ve figured the internet out — whatever you want to watch I’ll make it for you, ‘but not that one’. First the power bank: make a 9600 (mAh) one, charge it up; I’ll use my own nickel strip; basically done; they don’t even give you fish paper, use this instead; do the cushioning first; real materials; power on, try charging, try discharging, done, and not bad looking, sis, you get a discount. Starts fine but the chain isn’t cutting fast — chain off, really hard to get off, way too much material removed, mind the chain tension, ¥5; a drill that won’t turn, oil coming out (singing); find a screw, charging for the screw and the gloves isn’t unreasonable, ¥5; another one won’t turn, the wire is spliced, snip a section, wire is bad; brute-force it in; a special tool for taking the blade off, ¥15; done. Comments: list of Douyin’s 6 great logistics organizations (4421 likes); petition of ten thousand to see the tree at the door (3161, ‘I said no’); can this be fixed, it keeps saying wrong password (249); which store sells genuine 18650s; welder link / brand; how much for the power bank.

Outcome

GoalBuild a power bank by viewer request + everyday tool repairs
Build66W kit power bank (9600mAh)
ResultCharges and discharges fine; chainsaw, drill etc. fixed · verified on camera: 60–74s power on, charge and discharge test

Steps6 steps · click a frame to jump

  1. 1. Make a 9600 power bank, own nickel strip

    Whatever you want to watch I’ll make it; make a 9600 one; charge it; I’ll use my own nickel strip; basically done.

    00:01 – 00:26
  2. 2. No fish paper included, use something else; cushioning first; real materials

    They don’t even give you fish paper, use this instead; do the cushioning first; real materials, right.

    00:26 – 00:53
  3. 3. Power on, charge / discharge test, done, you get a discount

    Power on; try charging; try discharging; done, and not bad looking; sis, you get a discount.

    00:57 – 01:14
  4. 4. Chainsaw chain swap, hard to remove, ¥5

    Starts fine, just the chain isn’t cutting fast; the chain is really hard to get off, way too much material removed; mind the chain tension; how much, ¥5.

    01:14 – 01:45
  5. 5. Drill won’t turn, oil coming out; charge for the screw and gloves

    Won’t turn; oil is coming out; this song is kind of catchy; find a screw, charging for a screw and the gloves isn’t unreasonable.

    01:53 – 02:31
  6. 6. Another won’t turn, bad wire snipped; brute-force it in; special tool for the blade, ¥15

    What’s wrong, won’t turn; this wire is spliced, snip a section; wire is bad; brute-force it in; special tool to get this blade off; ¥15; done.

    02:32 – 03:38

Creator’s tips

  • If the kit has no fish paper, another insulating material can stand in; do the cushioning first 00:26
  • Mind the chain tension when swapping a chain 01:26

Pitfalls

  • The kit doesn’t include fish paper 00:26
  • Chain hard to remove, too much material taken off 01:26

Li-ion safety

DIY lithium packs can catch fire: check cells for shorts before welding, always add a BMS, never skip insulation and fusing on high-current builds.
