There is a few stores that falls under this category, an example of a brick and mortar store is "BrookStone" one online would be "NewEgg" These names are good because they have nothing to do with the products they sell but still resonate with there customers because of the products they provide, and is important that the name doesn't matter as much as the customer service the company provides for example think of your favorite convenience store, odds are that you keep going back is not because that its called "Food Mart" (or some other obscure name) it is because of product selection, quality, and customer service they provide.
With all that said you should not sweat the name as much focus on the polices and practices your store should provide to give your customers the best experience possible and build your name around that not the other way around.
Here are a few names for you just in case you just need a name
(your name first or last or nickname) Gadgets and Gifts
EX. Sully's Gifts and Gadgets
Gadgets Galore lol
Genius (dunno if that's already taken?)
Maybe name it after a planet? sounds strange, but words like Jupiter, Saturn, Venus, Mercury etc sound cool
