Quick Amazon search led me to this, it's fairly well rated. At $18.50 you can get a replacement or two for a reasonable price just in case.
I’m going to finish watching it later but I thought the same about the screwdriver. Sooooooo I found it
I have been using this model since 2006. I've had to replace it a couple times which seems normal. It works great: https://www.amazon.com/General-Tools-500-Precision-Screwdriver/dp/B002XZLTQO
Bakcpack I use is waterproof and big enough to fit my laptop, tablet, tools, media, cabling and still have plenty of space for my Nintendo Siwtch and Switch Pro controller. Space for molle attachments, fully adjustable/removable straps.
This is my tool for light to medium driving jobs. I use a second manual driver with interchangeable bits for jobs that require more torque.
Fuck it. Get this one General Tools 500 Cordless Power Precision Screwdriver https://www.amazon.com/dp/B002XZLTQO/ref=cm_sw_r_cp_apa_0EkzybSZS3N4Q
I've been using probably the same General Precision Screwdriver as you for awhile now and it works great for most small screws. There are a few that require a bit of a wrist flick to loosen. I havn't broken it yet but I was lucky to get this PLUS the General Cordless Engraver for $10 for both so not a big deal if it gives out.
For larger screws I either use a Black and Decker 7.2v Lithium Cordless Drill (very lightweight but powerful) OR a Ryobi Tek 4 Cordless Screwdriver (a bit heavier but has light on the chuck, removeable rechargeable battery, and a '2' speed setting for quick removal of loose screws).
