Suggestions Please: Battery Tender -- But No Outlet

Hoping someone has a solution for this problem. My garage has no electrical outlets and no way to plug in my battery tender. (Extension cords won't work, nor will anything else.)

Has anyone discovered a way to power a battery tender with an auxiliary battery, like a car battery or something similar? I'd be able to recharge the car battery in my apartment whenever needed, and I'm sure that'd be easier than trying to take out the battery on an F3 675 all the time.

Would love to hear any suggestions.

Boat owners in this area use solar panels to generate the small current required.
One of the features that sets the good ones apart is a diode arrangement that takes away the need to unplug when there is no sunlight.

You could just use a pigtail to hook up a car battery to the bike battery overnight as a parasitic supply.

These are great suggestions, thank you!
Unfortunately it's an underground garage with no windows to access sunlight
Do you think something like this would provide enough juice to power a battery tender:https://www.amazon.com/Suaoki-Portab.../dp/B06ZXYVG4G

I just installed a antigravity lithium battery... ytz 10-12 cell... 360 CA's. They don't drain themselves at all which basically means no real need for a tender. I would pair that with possibly that solar battery tender which might actually work indoors(off of whatever light is in the underground garage? Our F3's don't have alarms so the parasitic drain is minimal.

Why cant you get a sparky to put in a power point ?
Not very imaginative I know, but probably the best soloution

I think Lithium Fe04 battery still because it will actually help the life of the sprag. It spins the crank much faster now.

But another option would be to use a cigarette lighter inverter... if your bike and car are close to each other. I'm assuming you have a car in the same garage. It will cost around $50... but I'm not sure if you could really leave it plugged in for long periods unattended. Don't end up with a dead car and bike battery!
