Is the 1500VA the output capacity (Watts), and the 900W the draw for the battery charge?

In DC, Watt = Volt X Amp... therefore in DC, 1500 VA would equal to 1500 Watts. However, they are quoting you AC outputs, in AC, Watt = Volt X Amp X Power Factor, (In AC, voltage and ampere are not always in phase, so you have to figure out the integral of Volt and Amp, that integral is called the Power Factor)... So, in this case 900 = 1500 X PF... (The PF is 0.6)

Actually Volt-Amps and Watts are both Power measurements. However, due to the inevitable presence of capacitance and inductance in the UPS circuitry as well as the load connected to it, the UPS is rated at a reasonable maximum output of 900W.

From all I read about it and the instructions it says 1500 Watts. Hope this helps.

If everything else is the same.The 900 will last longer before it need charging again and may take a little longer to charge. Hope this helps.

It puts out 12vdc at up to 2 amps. If you only need 500ma, this has more capacity.

The one we got was the 500 Watt inverter. We don't have information on the 900 Watt one. So sorry.

In full sun mine at times produced 180 watts which = 15amps. But not all the time. depends on the sun.

Only if it is12v led. The battery is pretty stout, but you only have 12 ah (amps per hour). With that said you will have to calculate the rate it will drain the battery.DC watts to amps calculation formulaThe current I in amps (A) is equal to the power P in watts (W), divided by the voltage V in volts (V):I(A) = P(W) / V(V)So amps are equal to watts divided by volts.amp = watt / volt12 = 144w / 12vMax run time on a perfect charge/battery 12 hrs.

Dont know.... bought this as a gift ...I never recieved it .... but I've done enough Appliance repairs to know that 1500 Watts translatesto 15 Amperes: +/- oneAmp, and many times a low setting is about half that..... Hair Dryers, esp.......

The first answer is a bit off, because they did not consider the step down from the power supply at 12V to the USB slots at 5V. The power supply is 5A at 12V, or 60 watts. The 9 USB slots provide .9A each at 5V, for a total of 36.5 watts. Add the 2.1A at 5V for the charging slot, and you have a total of 36.5 + 10.5 = 47 watts. This is within the capability of the power supply. So, you should be able to deliver the full rated power to all of the slots simultaneously.

In case anyone was still wondering about this, I just received mine and the sticker on the bottom says that Output is 5V/900mA, so it's not a full 1A, but pretty close.

I have the 4000 mAh version which is not pictured on the page I'm looking at right now. But according to the back of it, it's Output is 5V ~ 0.5A.

The power source is battery.I think it is 9volts not sure but it is battery operated.

given the 1500 watt output at 120 volts ac, the amp draw during max power usage should be 12.5 (use the P = E x I equation).

I installed mine recently, and measured the power, but not the current directly. In standby, the KillAWatt shows 0W, and powered it draws 4.7W. This includes a small wall wart PS, with the illuminator attached by a 100' siamese cable. These numbers are close to what gth posted, so I'd rely on his more precise numbers.

I suggest you buy a converter which supports power at least 3 times larger than what you really need, this will make you less trouble. Thus for your PS, 500W seems good enough.

1500w if I remember correctly. Ours has been returned for the 3rd time and we still don't have it. Their service to the customer is horrible. If you happen to get an operable one, and it stays operable, they do a good job.

I'm using 315w at idle and I have 8 hard disks in this computer. At max load I use "only" 530w. So yea, I highly doubt you will ever use the full 900 watts.
