A:AnswerNutshell, about 4 hours. During the last power shutdown I left the refrigerator/freezer doors closed for about 6 hours at first. Then I plugged it into the power thing. It ran out of power after 4 hours. But, it worked! The power company turned things back on after about another 6 hours, and everything was fine. Nothing spoiled.
A:AnswerA Watt Hour is a unit of measurement for power over a period of time (an hour), or in our case, a way of measuring capacity. One Watt hour is equal to one Watt of average power flow over an hour. One Watt over four hours would be four Watt Hours of power. As an example, a 100 Watt light bulb on a 400 Watt Hour battery would last, on paper, 4 hours.
A:AnswerThe Duracell PowerSource has low voltage battery protection and the unit will shut down when the unit detects the voltage has reached 9.5 volts.
A:AnswerIt's hard to guess without the exact items, but this should recharge a smart phone from empty 35 times.
There's a bunch of people on youtube who are using these types of devices to keep decent sized 12V cooler shaped travel freezers/refrigerators running for days.
I'd guess a small college type fridge is a less efficient than those.
But it also depends on how full it is and how much you open and close it.
Same thing goes with the bed if you're constantly moving it up and down it's going to use up the stored energy quickly. If it's heated then it'll use it up very quickly.
If you want to you can add a bunch of lead acid batteries to give it much larger capacity or add solar panels to offset the drain put on it.
A:AnswerThe PowerSource can safely provide power to most appliances. In order to check if your refrigerator can run safely when using the modified sine wave the PowerSource produces, please check with the manufacturer of your refrigerator as there are some models that can only function when using pure sine wave power.
A:AnswerThe technology in the Duracell PowerSource is such that it sees both the internal battery and any connected external batteries as one large battery. Therefore, the PowerSource charges both the internal and external batteries at an equal rate. This is true whether plugged into a wall outlet, or using a solar panel. Unfortunately, the PowerSource cannot be used to jump a dead vehicle..
A:AnswerYou can use the unit while charging via solar panel. However, if the wattage draw is higher than the wattage coming in through the solar panel, you may still experience low voltage.
A:AnswerThe run time of the Duracell PowerSource depends on the wattage draw. We are unsure how many watts the described system uses, but based on information we found, the expected run time is about an hour before the Duracell would need to be charged.
A:AnswerI own the 1440watt version. The only thing I could think of. Is there's a issue in the wire or you could have a issue with the actual generator.
