Size- Dimensions

The first big difference you are going to find with the Coolis 150Wh portable solar power inverter generator (say that three times real fast) is the size.

Not only is it a mere 4.3 pounds, it measures 6.3×3.1×6.8 inches.

This is considerably smaller than most of the inverter generators on the market today and for good reason. This unit does not contain a gasoline powered engine.

Power Source

So, just exactly how does the Coolis inverter get its juice?

From its on-board 40800mAh lithium polymer battery.

In all actuality, this unit could be better described as a power bank, rather than a generator because on its own, it does not generate any electricity, but simply stores it for future usage.

Power Output

Power output on this unit is standard American 110 volt, 60 Hz, which means, theoretically, you could plug any 110 device into this unit.

However, since it is such a low wattage inverter, you want to limit the devices to those that are low load.

Run Time

Again, compared to generators as a whole, run time is not exactly an accurate description. The Coolis 150Wh portable solar power inverter generator offers a maximum discharge.

As one reviewer put it, you have approximately the equivalent of 5-6 recharges for a Mac Book Pro. Of course, one big plus is this unit has absolutely no noise output at all.

Calculate Working Time: Lets say your device is rated for 60w. Your calculations would be- 150Wh * .8 / 60w = 2 hours run time.


Since there are no moving parts in this unit, the maintenance is much simpler than the average inverter generator.

No oil or fuel requirements and no break in period required. Basic maintenance for the Coolis 150Wh portable solar power inverter generator is keeping it clean, free of damage and clear of water.


Where would this unit be useful?

Since you can charge it on any house outlet and now it comes with a solar panel connector, it can easily be kept ready for a multitude of applications.

Anywhere you may need to charge your phone, laptop or power other small devices is a good place for this unit.


Inside the Coolis 150Wh portable solar power inverter generator is a lithium polymer battery. Now days, most people are at least somewhat familiar with the lithium line of batteries, such as the lithium ion batteries present in most cellular devices and some rechargeable devices.

Lithium polymer batteries differ somewhat from their ion counterparts.

For starters, they are lighter and can be molded into different shapes. These batteries also offer a larger power output than the ion battery. On the down side, they are more expensive to manufacture.

Ease Of Use

Nothing could be easier to use.

Simply ensure your Coolis 150Wh portable solar power inverter generator is fully charged and you are good to go.

It is recommended that you do not discharge this unit 100%, as this can be hard on the battery and shorten its overall lifespan.

Environmental Friendliness

If there is one thing the Coolis 150Wh inverter is, it is environmentally friendly.

It burns no fossil fuels and therefore produces no exhaust fumes to pollute the environment. If you are looking for a simple way to do something green, this is a good start.

Customer Satisfaction

There is a direct correlation between customer satisfaction and their expectations going into the purchase.

Those who understood the limitations of the Coolis 150Wh portable solar power inverter generator were happy with the purchase.

However, those who expected a lot more from the unit were not.

Customers who bought it for casual use seemed to be the most satisfied as it suited their lighting needs at the campsite or emergency charge for their laptop and cellular devices.
