A few more on the footwear theme...

Deck Shoes - +1 to sailing and-or boating skills; or to any proficiency or skill when applied in a maritime situation.
Gumboots - +1 protection (AC and saves, or equivalents) vs water, marine creatures, or water elementals; they're also really good to chew.
Trainers - wearing these for an entire level's worth of adventuring will negate all training requirements, costs, or time when the next level is achieved.

Ray Gun: Stun setting optional.
Laser Sword: Cheap, generic-brand version. Works the same, but doesn't go "Vwhum-vwhum" when you wiggle it.
Billowy black cape: +1 to brooding.
Billowy white cape: +1 to posing.
Holy Hand Grenade: Smites the naughty within a 15-foot blast radius.
Robotic Assistant: Your Plastic Pal Who's Fun To Be With!
Comlink: Like a smartphone, but with only one app.

You could actually have a whole rainbow of these things, where red gives +1 to fire effects or bloodsucking, green gives +1 to hiding in natural surroundings, blue gives +1 to swimming or anything else done in water, yellow gives +1 to boasting (and also makes you visible for miles!), purple gives either +1 or -1 (situational) on dealing with royalty...and brown is cursed, giving -5 on all courage-morale checks or on resisting intimidation or fear.....

I'm pretty sure Lando has all of those.

Goth cloak - summons one barbarian who serves you black coffee, or fixes your black makeup

Power Armor - Tough protection, options for flying, sensors, enhanced strength, and blasting things.
Mac's Pocketknife - multi tool that provides a bonus in many situations.
Adrenaline Boost - injection for eliminating wound penalties, enhanced speed, combat focus.

Jedi Mind Trick - lets you get through a checkpoint without being searched (or even really scrutinized), control the roll of 1d6, or persuade a deathstick retailer to go home and re-think his life. Because this is a gadget not a power, limited uses per day.
