iFixit 精密電動ドライバー - 4mmビットコードレスドライバー 電子機器、コンピューター、電話修理用

Very less powerfull. Less impact. Not matched as per its pricing not feels like professional .

Other Low Star Reviews: Saw lots of bad or disappointed reviews on this before ordering it. I knew what I was looking for -- a cost effective precision screwdriver for proper mounting pressure on my GPU, and this made a HUGE difference. If you are looking for something with a lot more power to drill into or deal with tight screws, this is not the right product. It's low torque is a design feature. Torque/Power: This screwdriver won't enough torque in electric mode to remove some screws -- especially controller and phone screws that have had Locktite put on threads at the factory. For these screws, just don't use the buttons and manually break them loose by turning by hand, and then switch to electric mode to finish removing the screw. The speed is a bit slow on this driver as well, which is actually nice so you don't cross any threads and have plenty of time to stop if something doesn't feel right. Battery: Some people also whined that it needed AAA batteries and that they prefer rechargeable internal batteries... which completely goes against right to repair and iFixit's entire brand of right to repair and product longevity. Just use AAA rechargeable batteries, and you have ZERO downtime. Having replaceable batteries is a HUGE plus. Considering how little wear and tear something like this gets when used properly, I expect the screwdriver to remain in my PC toolkit for a long time, and if it had an internal battery, it would be an extra hassle to replace later, or the screwdriver would just end up e-waste like so many modern electronics. I have been using EBL branded 1100mAh batteries with zero issues. I did not notice any battery drain like some users have mentioned, but if I was going to store this screwdriver for longer than a few days, I would remove the batteries anyways. I removed a good 30-40 screws and reinstalled them across my entire PC and GPU during maintenance two days ago, and just used the driver again on another 20 or so, it's still going strong and hasn't slowed down yet. LED lights: The LED lights work just fine, but have no dedicated button, which makes the feature semi-useless. I already knew about this from other reviews, and usually just use a headlamp or real flashlight on such jobs, so it's not an issue. If you try to turn on the light by turning the screwdriver with a screw places on the end of a driver, you will likely find it flung across the room. Considering the device price of $20 USD, the lack of a capacitive/temporary or toggle switch for the LED lights is expected. Packaging: Strangely, both the small white box the screwdriver is shipped in, and the screwdriver itself have no iFixit branding on them at all. This isn't completely unheard of, just a strange choice. Perhaps the screwdriver wasn't made but is just sold by iFixit. However, looking up the UPC code (799559596750) from the product box confirms the screwdriver is listed as "IFixit Precision Electric Screwdriver", confirming the product is a genuine product. You can also find it directly on the iFixit website. My Use Case (A perfect example of what you need this for): I have a GPU (graphics card) that has had thermal issues due to unusual die design (Sapphire Nitro+ 7800 XT). I had re-pasted the card before using a manual iFitIt screwdriver from the Pro Tech Toolkit, and still had thermal issues. The RDNA 3 series of cards are know to have huge temp differences across the die, sometimes as much as a 30c delta between hot-spot and edge temps. Using a high quality paste or phase change pad like PTM 7950 helps a bit, but temps remained high on my card, a 27c higher difference on my edge temps. Carefully using this screwdriver to apply the right amount of torque to the back plate spring on my die dropped my edge temps on my GPU from a 27c delta to a 12c delta, using the exact same tube of Gelid GC Extreme paste I used previously. The slow torque applied by this electric screwdriver -- meaning it stops at a certain point helped for all the screws -- even those going through and into plastic threads for mounting the fan shroud. Everything felt secure, and didn't over tighten. The back plate spring is quite strong on my GPU, it's designed to apply mechanical pressure between the copper block of the heatsink to the GPU die, so the screwdriver stopped before fully finishing the job on those 4 screws. I simple turned the screwdriver by hand -- rated to 1nm in manual mode -- and finished tightening those 4 screws in a star pattern by hand to finish the job. I did this very carefully, only moving in 1/4 turns and switching between all screws to make sure the pressure applied evenly. The driver also worked great on motherboard screws, securing my quite heavy (GIGABYTE x670 Aorus Elite AX) motherboard to my case. No having to worry about the screws damaging the board and cutting or exposing traces in the future.

Used this on rebuilding my HOTAS set-up, it worked good, did not over torque the fasteners. Put it down for a week and went to use it again, it did not work. Changed the batteries and it worked. This item is not worth the time to remove batteries to save them or to keep buying batteries every time I need to use it. Went back to my iFixIt analog driver.

Es perfecto para desarmar computadoras y dispositivos electronicos pequeños, darle servicio a laptops, no tiene mucho torque el motor lo que evita que se dañen los postes donde se sujetan los tornillos.

Great electric screwdriver but I do wish they would give at least 3 to 5 driver bits cause it comes with none. Also it’s uses triple A batteries.
