VTOMAN FlashSpeed 1500 Power Station with 400W Solar Panel, 25% Efficiency

I was surprised at how well it can charge from solar, even in the UK. It's June, so starting to get more sun, but even on cloudy days I'm still getting enough to reclaim the energy spent charging a few smart devices overnight. On a sunny cloudless day, I can easily charge the full battery as long as I rotate the panels at least every hour or two. I was expecting worse :). Do note that if you are expecting to get 1.5kWh (or 3kWh with the extra battery) from the AC plugs, you won't. DC and USB you'll get pretty close, but the AC inverter seems to take quite a bit of power just to simply enable the plugs, so for my CPAP, I have got a DC-DC converter instead of using the AC plug, which makes it a lot more efficient. I would not recommend expecting to use the AC plugs all night / day, unless you expect to be able to fully reclaim the power daily. Having said that, that issue will not likely be specific to this device, converting DC battery supply to AC isn't very efficient generally.

Great product, and fantastic value as well. Bought as a bundle package with the 400w portable solar panel and an additional 1.5Kw battery pack. 3Kw power station that was at least £1000 cheaper than any alternative product. Like most, the only gripe is the display panel; it is far too dim and can not be easily seen, even under ambient light conditions. Fix that, and VTOMan will have cracked it. Whilst it will take years to pay back the investment, that isn't the point. I will power some house lights and my computer rig - I estimate it will save 50p a day. Doesn't sound much, but that is £180 a year, and it's green and gives you that overall smug feeling that you are at least doing your bit to save the planet.

Perfect for camping with the high output solar panels and the power bank lasts for ages

Ordered this to use at shows due to most petrol generators being refused - this charges super fast and lasts for all the duration I've needed being couple days to 5 days on fairly average usage The solar panels are huge and haven't used but I'd expect them to be just as good due to size and quality

Arrived a week early - excellent start. The unit was already 83% charged. Everything works as it should although it charged the remaining 17% at 700-800W. The build quality is good - as good or better than my Bluetti and that goes for the 400W solar panels too. Really looking forward to powering my camper van with the Vtoman Flashspeed 1500. Will update how that goes. The value for money is outstanding. This has twice the capacity of my Bluetti and with the panels still comes in at 2/3rds of the price!! As described on many Youtube videos, the product is spot on all round. Would it be too cheeky to ask Vtoman to send me one of the extra batteries to go with this as I can't find one for sale...will thoroughly test and review... :)

Waited four weeks to be delivered, the power station seemed to be a returned item, the box seal was tampered and wet, there’s also some scratches on the power station. Look somewhere when buying a power station, there’s a more reputable company than vtoman.

Absolutely great piece of kit and great discount package price deal from the seller The vtoman 400w solar and flash speed power station is ideal for off grid camping and handy for the house and working outside highly recommend one of these for your motorhome too for powering a microwaves hot plates and coffe machines
