I need to charge a smart phone, laptop and power a printer. Is 400 watts enough power?

We used this in the car on a trip. My son used it to charge and use his laptop. It worked great! I use my car charger for the phone. I have not used this item to power a printer. I would imagine if you are charging one at a time it would be sufficient power. Good luck!

Probably more than enough. A laptop is typically somewhere around 90-140 watts. Charging a phone through the USB port will draw up to 2.1 amps @ 5 volts = 10.5 watts. I have no idea on the printer, but it's certainly less than the remaining 250 or so watts. Assuming it's an inkjet, that is, and not a laser printer.

It works great for the Smart Phone and laptop, on the printer it will depend on how big of a printer you have.

Look at the power requirements on the power supplies for your devices. Then, add them up. These inverters have peek and continuous specs.

I charge an iphone, an ipad and run a printer while we are camping. The printer runs normally when both i devices are charging. This has not been a problem. I use the second 110 outlet at the same time to maintain a charge on a pair of walkie talkies.

Unfortunately, no. You need at the very least, a 400W power supply. I can't think of anything current that will run on 350W. Something from a couple of years ago maybe.

The 75 watt is great for pretty much anything you have i use it for my phone laptop almost anything that can plug into a wall charger the decision is more on preference and power needed. If the 75 watt can handle it then i would go for it but like i said its a lot based on preference.

The recommended minimum is 450w. However, my machine only uses a 192w when I'm using my my GPU at 100% on a i5 3570K. I think it will work fine on a 400w, but continuous use at 100% GPU may lead to a short life of your power supply.

The necessary power supply really depends on the components your using all together, but according to the Gigabyte website it says you need at least 400W.

Ideally would be 24 watts, without considering conversion losses etc. Being a switching supply, it should be close to the that (basic formula is P=I*E, P is power, I is current, E is volts).

As long as you have a sufficient power supply around 400-500 watts you should be fine.

I paired this card with a 400 watt power supply, and that's about as low as power supplies go. So I'd say you're safe with at least 400 watts.

Not a chance. The voltage isn't a problem, it's the wattage. 180W is good for laptops, and other small items. Vacuums, heating elements, etc. will pull in excess of 500W.

I would say yes based on a hundred watts per computer. So that would be 10 amps total. I assume this would be for over night charging or a class setting.

PNY listed the minimum power supply as 400W. I upgrade to a 650w to be safe.You may want to consider the same.

I am not sure. I have a laptop. I use it for storage and a printer/charge station.

Based on what you're mentioning - I'd go with the 2.1 Amp/10 Watt power strip myself. Many USB devices need at least 1 Amp these days, and 2.1 Amps will allow you to charge two at once. The 'Monster 'Outlet to go' is nice - but underpowered at 500 mA (0.5 Amp). Not sure how much your laptop needs to charge quickly - but many tablets need 10 Watts to properly charge.

The recommended way is to use a powered USB hub. The Pi is a bit power hungry requiring up to 700 mA to operate. Many use a small cell phone charger to operate it and a lot of them are only 1 amp, which doesn't leave a lot of excess power to run the other components. If the Pi doesn't get adequate power there can be some intermittent operating problems. The answer that Noel provided below is using an external 4-port hub, which I assume has its own power supply. Spend a few $ and get a powered hub!

Besides this kit you would need a tray cable that connects your controller to the battery bank. Since you would are doing 400 watts on a 40 amp MPPT we would recommend adding a 40 amp fuse in between the controller and battery.

Absolutely. Each is rated for 1875W. I use mine with a desktop PC, range extender, monitor, and printer running simultaneously.

From memory a 400 Watt PSU is needed. I went 500 Watts just so I could have a little extra.
