Has anyone used the TOPDON Tornado 90000 maintainer?

A bit pricey in my opinion. I use the snap on maintainer about $900. I am looking for a portable solution, however.

I like the Tornado 9000, haven't tried the 90,000. I sell them too. I find them less money than others. I was using Schumacher but if you have an issue outside of warranty the Schumacher becomes a throw away or an electronics project.

We had this running at Vision running 16 high intensity headlamp bulbs without a bobble. We also placed a 50 amp load on one for three hours without a drop in voltage. It's extremely stable with a 90 amp capacity on 12 volts and 45 on 24 volts. Pretty cool unit.
