DEVICES : Portable Power Stations.


Portable Power Stations are compact, battery-powered generators that can charge small items , such as cell phones and portable fans as well as common domestic appliances, for example refrigerators. So, assuming you fully charged the battery before a predicted weather event ; your portable power station could give you hours of electricity to run a refrigerator or any other essential appliance.

In an emergency, especially when we are in the hurricane and bad weather season, a portable electric machine, or as it is also popularly refered to as a portable power station, is the best option to have with you. If you need to power common personal electronic devices, and small appliances, while spending long hours without electricity wherever you are, these machines will help you spend that time with more comfort.

If you need to keep your electronic equipment running for hours during an emergency or whilst you’re on the go, these devices will be ideal for those requirements.

These devices are basically large batteries in protective cases, with built-in outlets and other ports . In an emergency, they offer some important advantages over portable gas generators, despite not being as powerful. The portable power plants that these machines have are quiet and emission-free; which means you can safely use them inside a home during a power outage. ALSO, since they don’t have an engine, there’s no need to have…….

  • gasoline on hand or
  • the oil changes or consider
  • other minor maintenance procedures that combustion engines require such as checking overheating issues.

To summarize, a portable power station is :

  • A mobile self-sufficient power supply as an alternative to the power generator for festivals, outdoor events, mobile work, etc…
  • A portable high-performance battery with charging electronics and inverter for outdoor, self-sufficient camping for caravans / mobile homes.
  • Ideal as an on-board power system for cars, mini campers, mobile homes or as a self-sufficient island system and solar generator for garden houses, construction vehicles, tiny houses and emergency power supply.

2).Diesel-Powered Generators vs. Solar-Powered Generators vs. Portable Power Stations.

Today, the most popular choice of generator is the solar-powered version. The reason for this is that when compared to the diesel and petrol powered generators, the solar-powered option can use the natural green energy from the sun and save the battery for powering up other devices also using an environmentally-safe power source. The portable power station can then be used on RV solar generators by connection to solar panels.

It’s important to bear in mind that both diesel and petrol-powered generators DO NOT create energy. They only store energy which is available at any time. The term ‘solar’ implies that energy is available when the generator is connected to a solar panel.

 The Solar Generator offers many other advantages:

3).Portable Power Station for Solar Charger Sets.

 A typical Portable Power Station is a super large power bank with a built-in 220V socket, USB, USB-C, 12V output and with a DC input for solar panels. Often there is also an advanced MPPT controller. Such a power station is super handy for solar charger sets, because then you only need a solar panel. Insert and it’s ready to use.A portable power station of this type is also much smaller and lighter. 

Features To Look Out For :

Being a super large power bank , it is supplied with a built-in 220V socket, USB, USB-C, 12V output and a DC input for solar panels connections.

With the older models, you needed a large heavy lead battery and a separate solar controller.  With that controller you had to pay attention to all kinds of connections (USB, USB-C, 12V in and out), and whether it was real MPPT. Also, for 220V you also needed a separate AC-DC converter. Hence you had to pay attention to the sinus: that had to be pure sinus, otherwise you could damage devices beyond repair.

Today’s portable power station solves all those problems, and is also much smaller and lighter in comparison to a power bank.

(i) An MPPT ( Maximum Power Point Tracker )

This is an electronic DC to DC converter that optimizes the match between the solar array (PV panels), and the battery bank or utility grid. To put it simply, they convert a higher voltage DC output from solar panels (and a few wind generators) down to the lower voltage needed to charge batteries.

The function of an MPPT charge controller is analogous to the transmission in a car. When the transmission is in the wrong gear, the wheels do not receive maximum power.

So, it’s very useful for a portable power station if it has an MPPT controller. Then a solar panel delivers more yield. But MPPT can be done in different ways, including digitally. It’s really just an algorithm.

(ii) Portable power station capacity expressed as Wh

The capacity is usually stated in Wh: that is Watt per hour. That is much better than Ah, because Ah depends on the Voltage. With Ah you don’t know whether it is at 5V, or at 12V or at 18V. Or at 3.7V? Makes a difference!

For example: 50Wh means that you can run a 50W device for an hour. Easy !

Or that you can charge phones for 10 hours with 5 Watts. Or that you can use a 100W device for half an hour. Or even a 1000 Watt appliance for 6 minutes (such as a microwave, kettle or hair dryer) – if the power station can deliver that much power.

A capacity of 50Wh is enough for a mobile household of four telephones, lighting, radio, speakers, iPad and laptop.

Name of Model Jackery Explorer 240 Jackery Explorer 500 Jackery Explorer 1000
Introduction / Review. The Jackery Explorer 240 is the smallest power station that Jackery offers. It takes up very little space and can be taken anywhere thanks to the carrying handle and low weight. Although you have portable power at your disposal, this will not be enough to operate a small refrigerator, for example. The Jackery Explorer 240 is more suitable for charging smartphones or notebooks. The Explorer 500 is Jackery's mid-range powerhouse station. It has an output of 500 watts and can also operate small camping refrigerators at least for a certain time. TV, beamer or similar can also be used for up to 8 hours. Naturally, charging the Jackery Explorer 500 takes significantly longer than the Explorer 240. It takes around 9.5 hours per solar module. The power station can be fully charged in around 8 hours using a cigarette lighter or socket in the house. The Jackery Explorer 1000 is the second largest and most powerful power station sold by Jackery. It is suitable for all campers and outdoor friends. At 10 kg, it is significantly heavier than its smaller "siblings", but the dimensions are extremely compact at 33.3 x 23.3 x 28.3 cm. The power station can therefore also be accommodated in the car. Thanks to more than 1000 Wh, televisions, refrigerators or projectors can be operated for up to 17 hours. During use, the power station can be charged during the day via a solar module.
