4.Ego Power + Nexus

At the first sight, it looks very classy to buy. You would have come across many generators having good specifications but they cannot tolerate bad weather. But this type of generator is weather resistant. It is lighter than the Yeti 3000.

There are two big disadvantages to Ego Power + Nexus. The first and foremost is the low battery capacity. Though the batteries are in good condition, they have low capacity. If you purchase additional batteries to boost the energy level, the maximum capacity is only 30Ah of power. If you are looking for a large-capacity battery, then this type of generator is not for you. The next challenging problem is, Ego Power + Nexus cannot be used as a long-term power source. Unlike other power stations, it doesn’t support recharging by solar panels. It has excellent 56V lithium batteries. The Nexus have to overheat and overloading the shut-off with warnings. Thus, a small device can be used to control and monitor the functioning of the generator with the help of Wi-Fi connectivity. The quality of the design is the top class. An added advantage is that it gives a remarkable 5-year warranty on the indoor generator and 3-year for the batteries.


  • Weather resistant
  • Low cost


  • Low battery capacity.
  • No optimization of solar panels.

Determine the requirement

The first question that first pops on our mind is, where do you install the generator? At home or at the office? Next question is, what are all the equipment you need to charge during a blackout? The best way to avoid confusion is to make a list of items that are needed the most during power outages. Walk around your house to determine which are the necessary appliances that needto be charged during a power cut.

Calculate Wattage requirement

You must determine the Wattage requirements in advance. Because in general indoor applications require less wattages than that for outdoors. Hence you must be smart in choosing the generator with appropriate specifications to avoid wasting of money and power.


Once the requirements are decided, then we are ready to look at the budget. Indoor generators are available in all prices, sizes, and shapes, you have to decide the budget that will suit your requirement.

Charging Options

The indoor generators don’t require any refuelling but there is a need for an initial level of charging the battery. The easiest way of charging is done by using the main electricity. The most effective way of charging is to connect the power pack to the solar panel. It helps in reducing the charging hours. You can charge the smaller power packs by plugging them to the lighter socket in your car.


Generators might be difficult to move. The generator can be huge in size and can take a lot of effort to lift. When you have appliances at a distant place, it might be necessary to move the generator from one place to another. Hence, portability is an important factor in deciding the best indoor generators. Although Portability is an advantage, there is a trade-off between portability and power.


An inverter can convert direct current to alternating current. The power supply is safe only if the power bank has a true sine wave inverter.
A low budget power bank may use modified sine waves which is less efficient. Hence you have to check whether the power bank can provide pure sine wave power.
Here are some of the Top 6  indoor generators.
