STORMROCK Portable Power Station: The Pursuit of Superior Performance

There is no doubt that fast recharge has become one of the criteria used to measure the excellence of a portable power station, especially high-capacity power plants. The solar generator not only has a massive capacity (614.4 Wh) and 700 W (surge 1400 W) of AC pure sine wave current, but also needs only one cable to achieve 500 W recharging efficiency. STORMROCK has a very mature technology for fast recharging. In terms of safety and solar energy utilization, the STORMROCK solar powered generator has likewise achieved high levels.

*500 W bidirectional inverter fast recharging tech, exceeding counterparts at the same specification, recharging to full in 1.4 hrs;

*614.4 Wh capacity, sufficient for a carefree outdoor camping or a power outage;

*700 W pure sine wave, capable of powering the majority of appliances, without damages on sensitive devices;

*120 W solar input with built-in MPPT controller for higher efficiency, STORMROCK 120W solar panel made for it;

*Variety of fast charging ports(type-c PD 100 W), high efficient.

Design Philosophy of STORMROCK Portable Power Supply

Design is aesthetic and pragmatic. The STORMROCK 700 W portable power station is compact, each plane is connected by rounded curves for ultimate elegance. It's so popular because it's not only 17.8 lbs, lightweight enough for camping, but also a performance monster. The entire central frame is painted in dazzling silver, simply gorgeous, when the foldable dual carry handles are stowed away, you'd rather believe it's a work of art, but its quality is as firm as a rock in a storm, this is the brand-centric positioning we want to implement -- "STORMROCK".

Obviously, the STORMROCK electric generator takes your breath away when it comes to charging speed via wall outlet (1.4 hrs to full). It also supports 120W solar/car DC input, the integrated MPPT controller coordinates the output of the PV module with the optinal power of the battery, boosting charging efficiency. Any solar panel that fulfills the input voltage/rated watt of the solar generator can charge it. The StormRock 120W solar panel comes highly recommended.

FAQ:

1、What devices can STORMROCK Power?

Each pure sine wave AC output supports 700 W (surge 1400 W) max power output. So you can safely use any appliance that power less than 700 watts, but the total load power of the two AC outlets should not exceed 700 watts. High-wattage appliances over 700 W (like induction Fryer, hairdryer etc) can not be charged.

2、How to solve the problem of inaccurate display of remaining power at the first use?

Due to low power status during transportation, the residual power showing on digital screen may be different from actual power. It will get normal after charging and discharging for 2-3 times.

3、How to calculate the working time of electric generator?

The portable power station has an output conversion efficiency of 85%. Divide the operating power of your appliance by (614.4 Wh * 0.85) and you can roughly estimate the duration of the power station.

4、In addition to having a 500 W AC input, does STORMROCK have an efficient solar input?

Of course, apart from the superior bi-directional inverter technology, solar recharging is also competitive. The DC 5521 standard input has an OCV (Open Circuit Voltage) of 12V-24V/5A and a maximum 120 W input power. The built-in MPPT controller delivers the maximum power to STORMROCK power station with minimal losses. Together with the highly recommended STORMROCK 120 W solar panel, they make a powerful solar generator.

Note:

*When first used, the battery should undergo a complete charge and discharge process, first depleting the battery capacity to 1% and then charging it to 100%.

*Choose a dry and well-ventilated storage environment and prevent moisture and liquid from entering the product to avoid circuit failures or corrosion of electronic components.

*STORMROCK power station should be charged at least once every 6 months to extend the lifespans of the battery cells. When taking out the product after long-term storage, please full charge it before use.
