It's mentioned in the review. It reaches 38°C in turbo, or 43°C if you activate turbo again. That's rather moderate for a modern flashlight. Usually I set my limit to 55°C - not because the flashlight would be damaged, but that's the limit I can comfortably hold in my hands.
That photo doesn't look like a Sofirn LT1S at all.
You mean Li-ion with integrated step-down converter? They usually require their own special "charger", there's no universal standard.
Usually I have my eyes closed during showering (without glasses I wouldn't see much anyway). So not much light needed.
I had the Slimblade for five minutes, until I quickly returned it because of the bad buttons and the high ball without a proper wrist rest. Eventually I found the Elecom Huge which was just perfect for my hands. The Deft Pro works also great. Tried various other trackballs including thumb trackballs, but none worked as good as the Huge for me.
Indeed, it's an Elecom Huge. Also have some other Elecom like the Deft Pro and still thinking about getting a Bitra (although it might be too small, but not much more portable than the Deft Pro).
No, I'm in no trackball group. Just using them everywhere.
It seems to be available at their AliExpress store: https://www.aliexpress.com/item/1005006374608354.html
Nope, there isn't.
Just in case someone thought they had a deja-vu: I reposted this because my original post went missing when Feddit had to restore an old backup after a crash.
Yes, it is 6 V and draws about 5-6 A (I've measured 11 A at the battery).
SFT-40 would be a good choice, indeed.
With some imagination the lanyard could be seen as a ring.
On the other hand, I just tried to stab myself and it didn't hurt. Definitely no real kunai.
