It is my understanding that the answer is dependent on comparing the charger input in volt-amps with the output of the inverter. The general formula is that amps are equal to volt-amps divided by volts. Your camera's specifications require an input of 21 VA at 100 V or an amperage of 0.21. This Bestek model produces… see more It is my understanding that the answer is dependent on comparing the charger input in volt-amps with the output of the inverter. The general formula is that amps are equal to volt-amps divided by volts. Your camera's specifications require an input of 21 VA at 100 V or an amperage of 0.21. This Bestek model produces 300 to 350 watts (volts x amps) at 110 to 120 volts, or slightly less than 3 amps which is greater than the 0.21 amps required by your charger and therefor should work. see less It is my understanding that the answer is dependent on comparing the charger input in volt-amps with the output of the inverter.

I believe it should work fine. We used it to charge phones and power laptops all at the same time. Not sure how smooth the ride is and the WII not skipping..its just like a DVD player

In my opinion any half decent electronic should last more than 5 months. If your thinking of replacing it with the same one, had ours since August And its "stored" on the floor of my car and still works. I agree you should contact the manufacturer.

You must check your vacuum for wattage. It has 300 watts continuous power and 700 watts peak. Continuous is for normal operation and peak is for initial motor surge. Both must be below the 300/700 watts rating. Unless it's a tiny hand vacuum, I would not. It was built primarily for electronics and small electrical… see more You must check your vacuum for wattage.

Vacuums and blowdryers normally fall in the 800 watts+ range inverters. see less You must check your vacuum for wattage. It has 300 watts continuous power and 700 watts peak.
