VoltX M2400
VerifiedMPN: S2200PRO2 reviews
As another reviewer has said, the fan noise from the Voltx 2400 (S2200pro) is loud when it’s being charged. I can understand the fans needing to cool things down when it’s fast-charging from mains power, but it’s also loud when charging from a solar panel - even if the power input is under 50w on a cloudy day, this thing sounds like a jet engine. The unit itself does not feel hot and it’s out of the sun so I don’t know why the fans need to start up on such low power input. I wouldn’t have bought it if I’d known this but unfortunately there wasn’t many reviews around when I was looking to buy. I’m hoping there will be some firmware update to fix this because otherwise it’s great.

I received the Voltx 2400w from Big W Marketplace seller Ozzie Energy quickly. It was delivered well packaged and fully intact. I have used the Voltx 600w for over a year now, and have been very impressed with the product's quality and performance. so had no hesitation in purchasing the Voltx 2400w despite its weight of 27kg. I haven't had a chance yet to put it to lengthy use but have tested it with various 240 and 12 volt appliances. It performed well and only used 1% battery power to boil my 240v 1200w kettle. It does have an annoying and quite loud fan when I fully charged it from mains power, as well as when I used it to boil the kettle. However, I hope I can overcome this with some sort of soundproofing in a type of baffle box construction. It was silent when I plugged in my 12v freezer and also silent when I switched over to 240v when the freezer had achieved the desired temperature. I am not sure if the whirring of the fans should be as loud as they are so am hoping some soundproofing will rectify this. It is a little troubling that such a hefty portable power station does not have any tie-down anchor points or grab handles on either end. It only has the top handle so make sure you are strong enough to carry it this way - grab handles on either end would help enormously with balancing body weight when moving it about. I am a small woman on my own so I will have to invest in some sort of trolley to move it around until I can figure out how and where to permanently fix it in my van. Overall, to date, I really do love and recommend the Voltx products I own: 160w Solar Blanket, E600w and M2400w power stations.
UPDATE: I have been able to reduce the annoying whirring sound of the fans by strategically lining the battery's ventilated storage box with sound deadener and some XPS foam board to barely a hum. Very happy! At the moment I have it attached to anchor points in the storage box with short ratchet straps through the handle - a solution that I hope to improve on with use and experience.
Thank you for the review. It is a fantastic, detailed review! It’s really helpful to hear how it handled a 1200W kettle with only 1% battery—that’s impressive efficiency.
Great contact from VoltX as always. To be transparent, I should of mentioned that the kettle has only a 600ml capacity and I only put around 450ml water in it - I am always trying to be thrifty and energy efficient so no point in boiling more water than I need or can use.

Thanks for sharing this—we completely understand how frustrating the fan noise can be, especially at low solar input. We’ll raise this to our technical team for review, particularly around fan behavior and possible future firmware improvements. We appreciate your feedback and are glad to hear you’re otherwise enjoying the unit. Cheers.
