Really small battery compared to everything else on the market , there were a few here on the Gold Coast for testing no one got one . Probably best on the ding it's a pretty big unit when it goes in the water there is a ton of drag .

Here is a good video , compares to other brands of foil assist products .

I've used the Stoke Foil Boost with a SUP and find that it works great. Super easy to give you the boost you need to get on the wave and then the wave does the rest. Battery lasts ages if you just use it for boosts to get onto waves. I recently did a 3 hour session and still had almost 50% battery left. But, if you use the Boost to power you back to the lineup you will go through the battery much faster. Personally, I try to only use it for the boosts to maximise the battery and also to not get lazy and actually get some paddling fitness too back from the waves.
