Maybe this one?
Warsun X608
3 mode * 2 but easy to understand, no double or triple click needed (hold button to change from LED to COB)
Big battery already there
Built in charger and powerbank
Cheap with coupon (16$ Archive topic - Banggood & Fin17)
Magnetic tail, holds it horizontally without a problem
not super small, so easy to hold and hard to loose
