AUTOGEN Single-Stage Vacuum Pump 3CFM 20V Lithium Battery DC Inverter 60 microns 1/4HP for Air Conditioner Refrigerant HVAC

I've used this to pull a vacuum on a 5 ton rooftop unit. It didn't take long and it still had battery enough for a couple of compressor changes on small coolers. If you do a lot of rooftop work this is well worth the money.

No me llegó el cargador de la batería, que procede?

This thing is so light and easy to carry on to the roof of commercial buildings. I no longer have to wire in an outlet to get power on the rooftops. And it actually works fast. The only complaint I have is the service port is so close to the handle, that my low loss fittings will not screw on unless I loosen the handle and turn it sideways. No big deal though. I can either add an adaptor, or just keep turning the handle. Either way, buy it! You will not regret this purchase. I don't. I've been in the Refrigeration business 25 years. Everything is on the roof of these restaurants.

La batería no dura no la recomiendo
