Have recently bought a smart trainer that needs power. I do not really have room indoors but have a shed at end of the garden. It’s about 80metres away so too long for an extension lead. Would a leisure battery set up do it?! If so, what would you recommend?

How are you going to get the correct voltage from the battery into the turbo mate?

Regulate it down to the correct voltage, ie 5v (even if the turbo needs 12v, the battery will likely output over that which *might* be an issue without regulation) or whatever?

Or.... use a inverter to use the original power supply?

Both have good and bad points.

(PS, I want your garden.😁)

See if you can find out the spec for the power supply for your turbo trainer. Looking at a replacement power supply should tell you.

If you can find a 12v power supply to match then you’re sorted.

Sorry to sound thick but where would I find that info?

The turbo should have come with a power supply.

Look on the bottom of it to find the rated output in volts and amp.

If it's 12V or 24V, buy a cheap car battery and charger could be an option.

If you're not sure what your looking at, take a pic of the underside with the label on and one of us will decipher it for you.

EDIT. If you sort it yourself, make sure you get the polarity correct or else it could damage the circuitry in the trainer.

Can you rig up a system so the turbo charges the battery that feeds the turbo?

Longer extension lead?

Or use an inverter on the battery.

Wahoo do a 12v car adapter for the kickr, maybe this could work for you with a car battery

I think I’d be moving the shed if it was me 😀

It's not like he'll crash into anything!

How about running a cable out there permanently under the ground?

Clearly the only option is a poweroak 2400wh power bank, you could also run a fan and light for only just over 2 grand

Why's that too long for an extension lead (or 2). Other than the hassle of putting it out.

Is there not a solution with a capacitor and a Dynamo?

I can't be arsed to work it out but it's going to depend on battery size/quantity, trainer type and the losses if you have to use an inverter.

1/ How big is your garden, FFS?
2/ Why is a longer extension cable not an option
3/ I'd be looking at a permanent extension - lights/fans/TV, etc

I've had a 30m external extension to my shed or the last few years, just cut a slot in the grass for it. Powers lights, turbo, laptop and has Internet through it too with no issues

If you have an 80 meter long garden surely you live in a stately home. Isn't there room for the turbo in the servants quarters?

If you had a tacx neo you wouldn't have this issue as it can be run without power I believe, although i have yet tried it.

Tacx neo works well without power, just doesn’t have driven freewheeling without power. Still need plenty of power for the fan, tv etc.
