1000W Pure Sine Wave Inverter 12V VP

Should be OK for the juicer which is probably under 300 watts and the laptop will be running on the internal battery which will be plugged into the inverter. I read the instructions and they seem comprehensive unlike the cheap 2000watt inverter I bought for a similar price. I've attached the pdf link below if you haven't read it already.

The company has no bad marks that I can find so if you have problems hopefully they will cover it.

Good Luck.

EDIT...forgot to mention that mine blew up after a week and it took many emails to eventually get a replacement motherboard from China despite the seller being a big Aussie based company. I only add this as what can happen but should not.

Although large inverters seem attractive, they need large cabling, large battery banks, and they have large standby current (just being switched on uses power) and the cheaper variety are quite inefficient.

Would be a better idea to find out the exact loading of your juicer in Watts and size a quality inverter to that. Most better quality units have lower standby current and are more efficient.

I have a Morningstar Suresine 300W unit that has a surge rating of 600W and has no cooling fans and above all requires low standby and smaller wiring. It can be remotely switched or auto load sensed switching.

There are other good quality units out there such as Victron or Stirling.
