I was just watching Jeff Kendall-Weed's review on the Pivot Shuttle Amp'd and he briefly mentioned that using the Avinox quick charger fried his Jackery (and Jackery wouldn't cover it under warranty). He didn't really explain this issue other than saying he doesn't recommend using one to charge. Does anyone use a Jackery to charge their bikes when out at the trails? I know lots of people use it to charge other ebikes... just not an Avinox new or old.

The Avinox GaN fast charger creates high inrush spikes when plugged in, plus peaky current and high freq noise that can stress power station inverters way more than a normal resistive load (like a kettle drawing >2kW doesnt fry the power station because its normal load).
But that said I use an Anker c2000 gen2 and no issues yet. Anker even promote theirs for charging ebikes. I'd imagine its rare but it definitely could happen to any portable power stations because of the spiky load.
If you're worried an option is to use the slower 4A charger off the power station instead, same thing but much gentler on the initial spikes.

I don't have my avinox bike yet.... does the charger have a switch to toggle between fast and slow charging?
He did reply to my comment on the video and said he thinks the charger just drew too much power, so I'm guessing his Jackery just wasn't rated with a high enough capacity for that much draw.

What does the fast charger draw? My fast shimano charger only uses around 130-150w max. I can charge two bikes at once easy with my 600w power station

508w
I have a DJI power 1000, the inverter rated around 2500w from memory, had no troubles fast charging.
Seems a bit odd from jackery, the smaller the powerbank the lower the inverter tends to be rated but they usualy have inbuilt protections rather than frying themselves.

At least Pecron units are cheap. If I end up with Avinox might need a bigger power station.

I think Jeff did mention in one of his replies that his Jackery was a 1000 w unit. That's a smaller size for them.

Anyone experiment with this? I'm wondering if I need to stronger power station. I have a 600watt one now.
We are using Jackery / DJI and Ecoflows. No issues at all. The Avinox 12a fast charger only draw around 450-480 max so as long as your portable battery can maintain over 500w (almost all of the modern ones easily do this) you should be fine.
I have an EcoFlow and it is around 3,000 watts. I personally would use the slow charger only since slow charging is generally better for battery life and health. I am not an electrical engineer so not sure how the fast charger will fry a charging unit that exceeds the watts of the battery by let's say 2X. I can see it frying a small unit just by overwhelming it with its high draw.

I agree. I bought both chargers. Ill need the fast when doing long days and charging at lunch. Which isnt all that often for me. Usually do a 3 hour ride
I use the ECOFLOW River 2 Pro Portable Power Station 768Wh 1600W Max, with my 12A Amflow charger. There is an initial inrush of current to the Amflow Fast Charger, as the capacitors charge up. As long as your inverter is designed to protect itself against inrush. It will be fine.
If it isn't. You can have problems.
