If I am not mistaken, Sofirn designed and released the SP36S due to some (or a lot of?) customers feeling overstrained by Andúril's complexity. The BLF edition has probably not sold as expected. I also guess that the SP36S is a product related to Barry's recent thread about customers complaining about too much excess heat while using a flashlight. With 55°C and 2min stepdown in place, Sofirn maybe wanted to address these complaints.

My conclusion: The SP36S is not meant to be THE ultimate BLF flashlight but a mass product for less experienced (Amazon) customers.

The full manual can be downloaded from my sharepoint: ► Link

The SP36S is also available on Amazon DE: ► Link

I can confirm that the SP36S is capable to charge with up to 18W (12V @ 1.5A), i.e. QuickCharge 2.0.
