- Everything You Need to Know

Whether you live in an area prone to natural disasters or you just have occasional power cuts, or you’re happen to be an outdoor enthusiast ...power outages are disturbing. Where we are saying we want to get away but we really don’t want to let go of our smartphones and other gadgets. While most indoor generators are gas motorized and can be used only outdoor due to the noise and smells, having a backup source such as a battery or power station portable is top on the list of household necessities. Portable power stations provide electricity through large batteries that are safe to use indoor and have a variety of charge ports. Plus, they’re a bit more portable, so you can actually take them with you on off-the-grid excursions.

What is a portable power station?

Portable lithium-based power bank, also called portable solar generator or solar generator, can be a life saver for camping and other unexpected extreme weathers.

Solar power generator is the smaller, mobile UPS rechargeable battery-powered generators. Equipped with portable outlet like AC outlet, DC carport and USB charging ports, these versatile, portable cooler-box-size gadgets are ideal for backup power supply, extended camping trips, construction sites, and other unexpected situations. Whenever & wherever else you need a reliable source of electricity while on-the-go, you can charge all your equipment, from smartphones, tablets, laptops to CPAP and small devices such as camping lights, fans, mini-coolers, electric blankets, etc.

How does the power station work?

In fact, portable solar generator like a DC to AC inverter that increases the DC voltage, and then changes it to alternating current before sending it out to power a device, like your laptop and TV. The DC input port collects and store the electricity/energy from an AC outlet or a portable solar panels and output through built-in USB ports, DC carport or an AC outlet. it’s like the oversize power banks simply charge & store electricity, and distributed safely, quietly, and without harmful by products. Portable lithium power station are distinctly more capable than pocket-sized cell-phone chargers, most of which cannot charge anything but a smartphone.

Because electric generatorserves as an emergency backup battery power supply to charge electronic devices or even operate home appliances for outdoors and disasters. The best portable rechargeable power station should offer enough capacity from family camping trips to the toughest expeditions, charge smart devices and small appliances multiple times, hold up in the event of inclement weather or power cut, and have a variety of charge ports to be compatible with a range of plugs.

    Portable Solar Generator Terms and Conditions you might need to understand:

    CAPACITY (Wh): solar powered generator 1000wh stands for Watt Hour and it is how a battery's energy storage capacity is measured. Watt Hour is now the more common way of measuring battery storage since it accounts for both capacity and the voltage and gives a more accurate measure of how long your battery will last.

    Example for 300w solar powered generator, 307Wh: AC output working time=307wh*0.85(efficiency)/the power of your device

    Assume your power of device is 50W, working time will be 307wh*0.85/50w=5.22 hrs ( rough calculated )

    ACTUAL CAPACITY: Some manufacturers may not round up the solar powered generator watt-hours in their model number or subject, so a “300W” might really be a “280Wh” Read the label. And, not every device supplier actually discharges their advertised watt-hours, though there is very little actual test-based data on this point.

    CHARGING INPUTS: solar power generator can be charged indoors and outdoors using three types of charging, like AC outlet from Wall socket, DC carport from vehicle's 12V output, or via optional portable solar panels.

    Usually solar generator can be recharged by portable solar panels about 6-7 hours in full sun(100W); and fully charged from a wall outlet about 6-7 hours; By 12V car charger about 6-7 hours.

    How to charge portable power station

    PORTABLE OUTLETS: Multiple output ports connecting different device at the same time. USB connection like tablets, iPhone, iPad, laptops; AC ports like fans, TV, lights and CPAP machine. Car port like car vacuum, car freezer etc. It can also output power while being charged.

    It’s important to know if the solar powered generator you’re reviewing supports pass through technology, means if it’s capable of charging and discharging at the same time.

    2* AC Outputs at 500W (peak 1000W), voltage at 100V/110V or 220V/240V, US-standard outlet for Phone, Tablet, Laptop, CPAP, Fishing light, Lamp, Fan, Christmas lights, etc.

    1* 18W USB-C Port that charges iPhone, iPad, Galaxy S9, Pixel, drones, cameras, and more

    1* Fast Charging USB3.0 Port; 2* 5V/2.4A USB Ports that support 12W per port

    1* 12V/8A Car Port(Cigarette ligher) that supports 96W, such as car vacuum, car refrigerator, CPAP machine, etc

     2* 12V/4A DC Outputs(5.5mm) that support 48W per port.

    500wh solar power generator would be powerful enough to charge smartphones (2000mAh) 70 times, laptops (56wh) 8.5 times, mini car fridge(45W) about 10-18 hours, 32" TVs ( 75W ) 6-7 hours, mini projector (60W) about 6-7 hours or other small power appliances.

    CHARGE CYCLES: Typically used to specify a battery's expected life, as the number of charge cycles affects life more than the mere passage of time. All manufacturers claim their power stations can be charged 500 times before capacity starts to falter. But more likely you’ll be replacing one of these things with improved technology in a couple years perhaps, before it fails as charging cycles.

    PURE SINE WAVE TECHNOLOGY: This is better than modified sine-wave (MSW), because the total harmonic distortion is higher in MSW inverters, motors will run hotter (less efficiently, consuming up to 30% higher), and likely not last as long as pure sine wave device. Additionally, a MSW inverter will often cause a “buzz” to be heard from audio devices. Pure sine wave AC output provides clean power which is safer for sensitive electronics

    LIGHTS: Some solar power generator have built-in LED flashlights. Usually press the button once for immobile white light mode and press twice for SOS mode, very handy and useful when power goes out at home whether due to a hurricane or other natural (or unnatural) events, the emergency flashlight will help to keep outdoor adventure safe in the dark as well.

    built in flash light

    DISPLAYS: It tells you when it’s charging, what rate it is charging at, and how much capacity remains. Mutifuction LCD display that shows battery operating status timely (include AC output power or load, battery capacity or percent, over-temperature, battery failure alarm). It is useful with bright emergency light good for outdoor illumination or emergency.

    TEMPERATURE RANGE: Lithium batteries rely on chemical reactions to work, and the cold can slow and even stop those reactions from occurring. And very low temperatures affect their ability to store and release energy as well.

    Since cold conditions drain these batteries, you’ll need to charge them more often. Unfortunately, charging them in low temperatures is not as effective as doing so under normal weather conditions. Most of these devices are said to operate only when temps are between 32 and 104 degrees Fahrenheit. If that matters, check.

    DESIGN: Some of solar power generators are more ruggedly designed than others. Storing them in one spot garage or keeping in a box when traveling, physical attractiveness is less of a concern. Do make sure your portable power stations come with a handle (most have one).

    SOLAR: Portable solar panels, the sun is a gigantic supplier of energy! Whether you are an avid camper, or you‘re getting ready for the next fishing or hunting trip with family and friends, a reliable and consistent electricity supply is the key while you're looking for outdoor adventure. Solar power is an excellent option to increase the fun of recreation by using a stand alone portable solar panels, we’ll vote for that.

    FAQ on Portable Power Station:

    Q: Can I charge and use the power station at the same time?
    A: Yes! It has the pass-through charging feature which means that this unit can charge other devices while it is being re-charged.

    Q: What does Ac peak 1000w mean? Wondering if I can run a 1000w blow dry brush
    A: Its AC ports are rated at 500W continuous. 1000W peak means that it can endure 1000W load for a short period of time. But it can't work at 1000W for long time or continuously. Therefore it can't work with any device that is over 500W continuously.

    Q: How long does a 200W solar generator last?
    A: Run time depends on what device you use and what wattage it consumes.
    This is the method how to calculate runtime roughly (using AC port on this power station)
    Runtime= 180Wh / rate power of your device

    Q: How long does the power station take to full charge this solar portable power station?
    A: Usually it has four ways to recharge.It can be fully recharged within 5-7 hours by SolarSaga 100W in full sun. It can also be fully recharged within 5-7 hours by wall outlet, car outlet and generator.

    Q: Can I use the solar power generator to charge my CPAP Machine?
    A: Most CPAP machines are between 30-60 Watts. Watts is a unit of power and a function of current (amps) and volts (Watts= amps x volts).
    The working hours = Watt hours *0.85 / watts.
    For example, the power of the Resmed Airsense 10 is 53W, and without running humidifier: 518Wh*0.85/53W=8.8 Hrs

    Q: Can I charge many devices at one time?
    A: The power station portable outlets and powering options allow you to charge up and run multiple devices all at the same time. Simultaneously charge up to 10 devices without any fear of over-current, over-voltage or over-temperature.

    Q: How to store and charge the solar generator if I don’t use it for a long time?
    A: Please kindly store the power station within 0-40℃. And please recharge it every 3-month to keep the battery power above 50% if you don't use it.
