Good enough, bought two.

After only had the first unit for a couple weeks, it works as expected. Needed a little help from customer service and the response was within minutes. Needless to say I was impressed so I bought a second unit for a second cluster to electronics. I could have given it a 5 stars but since it’s a B-stock and only charge to about 13v not the full 14v as specs I suspect some degradation of the battery. Longevity is uncertain and it’s too early to judge.

General Questions

Yes. It will not overcharge the battery.

You need to push and hold the power button which will light up the screen, turn on the inverter and activate the UPS function.

The watt meter measures loads over 50 watts.

They are always on.

No, it can not be disabled. When the internal battery has 10.5 volts, the alarm will sound. Please turn off the unit or recharge it.

The Power Source 660 has a floating ground. When the unit is plugged into the wall, it is grounded through the wiring in the AC outlet. When the unit is used free standing, there is no ground, and it is just like any other appliance that has only 2 prongs on the plug.

The Duracell PowerSource is similar to a generator in that it is portable and provides AC power using a refillable energy source. This unit has a built in solar controller which allows it to be sustainably recharged using solar panels. It can also be recharged via the external posts from other sources such as a car's alternator or additional SLA batteries. Since the unit has an inverter, it does generate 110V AC. The difference is that the unit pulls the energy from a battery rather than from a gas tank.

The PowerSource has been tested to run a 16 cu ft refrigerator for 5 hours but run times may fluctuate from 3 hours to as high as 8 hours depending on compressor types and usage. Since a refrigerator can retain its “cold” for a few hours, you can turn on the PowerSource for 30 mins every 4 hours or so to maximize it’s run time.

The 1440 watt inverter will draw approximately up to 120 amps from a 12.8 volt battery.

No, the AC waveforms will not be synced, it is not safe and will damage both units.

You can connect (Daisy Chain) 12V Lead acid batteries to the terminals to extend your run-time. Red to Positive(+), Black to negative(-) The battery is connected to the unit by the 10mm posts on the back.

Yes. There is no limit to the number of batteries you can add to the unit, though it does increase the amount of time it takes to charge the unit.

If your cable is less than 4 feet long, you can use 4 gauge wire. Longer cables will require 2 gauge.

The larger the better however the built-in 6A charger will take a long time to charge larger batteries.

A circuit breaker can be installed on either the positive or negative side; Keep it as close to the external battery as possible-the breaker will protect the battery; the unit will protect itself.

150 to 200 amps is sufficient ex: 1800 (watts) / 12 v (input) = 150 amps

This unit has a modified sine wave which can cause some items with motors to make a buzzing sound.

You may plug a portable pure sine wave inverter to the back terminals, but you will not be able to use the 'instant on' UPS function on the external inverter because UPS function is only available from the front ports. We recommend only using products with NRTL certification (UL, ELT, CSA logos) and FCC approval.

We recommend using the shortest possible factory made cables with Anderson connectors to minimize resistance.

Items with heating elements like heaters, irons and cookers use 1000 watts or more and are an inefficient use of the battery energy. Additionally air conditioning units will not work with the PowerSource.

Questions about charging the PowerSource

Lead acid batteries are generally rated for 500 cycles before they reach about 70% of their original capacity.

It takes 10-12 hours to charge the internal battery from 0 to 100% when plugged into the wall.

Yes, the power from the wall outlet will recharge both the internal and external batteries as if it was one big battery.

Yes, but it is not recommended. You need to carefully monitor the charging, and cut it off when the battery reaches 14.6 volts, because it is DIRECT CHARGING.

Yes, there are 2 ways to charge from a gas generator: 1) If the generator has an inverter, plug into DR660PSS AC cord into the AC port of the gas generator. 2) If the gas generator has a battery charging port you can charge the DR660PSS using the daisy chain terminals but it must be carefully monitored and removed when the internal battery reaches 14.6V.

You may use a wind turbine WITH a charge controller for 12 v batteries. You will need to connect it to the Daisy Chain terminal posts on the back of the unit.

Questions about charging with solar panels

It takes 10 hours or more to charge the internal battery with a solar panel. Panel type, length of connections, intensity of the sun and atmospheric conditions all affect the power delivered to the unit.

100 watts is the maximum we recommend when using the built-in solar controller which has a 15A replaceable fuse inside.

You may use the 12v socket (15A max) on the front or the Daisy Chain terminals (120A max) in the back to connect a solar panel with external charge controller.

Yes, the PowerSource will recharge from the wall outlet first, and if the power goes out it will automatically switch over to recharging via the solar panels.
