Why Do Portable Generator Get Hot? – You Should Know More

It’s not uncommon for portable generator to feel a little warm. After all, a lot is going on beneath those shiny exteriors. Still, there is a big difference between warm and hot when it comes to portable batteries like portable generator.

A portable generator may also get hot due to a manufacturing fault, incorrect charging practices, excessive current, and short-circuiting caused by damage to the portable power station. A portable power station can get hot because lithium-ion batteries produce twice the energy of an alkaline battery and operate at a significantly higher voltage than other batteries.

While we may not know all the little tricks that keep our gadgets running smoothly, it’s essential to know when something is wrong. If your portable power station is overheating, you need to understand why and how to stop it from occurring in the future.

 

Why Is My Portable Generator Overheating?

Unfortunately, cases of portable generator overheating are not isolated, and organizations such as the United States Consumer Product Safety Commission have had to recall batches of portable generator due to overheating, catching fire, and even exploding .

While the chances of your portable power station exploding in your back pocket are pretty unlikely, it is still always good to be aware. An overheating portable power station is not only bad for you, but it can also shorten the overall life of the portable power station’s battery.

You may wonder why manufacturers choose to use lithium-Ion batteries if they are at risk of overheating. Due to the sheer power needed to run smartphones and tablets, manufacturers need to use lithium-ion batteries because their energy density outmatches both nickel-metal hydride and NiCad batteries (source).

Also, lithium-ion batteries are much lighter and more compact, which makes them ideal for portable devices.

Sometimes when a portable power station overheats, it’s due to a fault in the device’s manufacture. While consumer protection organizations are vital to keeping consumers safe, they cannot recall all malfunctioning devices. That is why you need to know the signs to look out for if your portable power station is overheating.

The first step is to establish whether it is a fault with the portable power station’s manufacturing or something you are doing. There are several possible reasons why your portable power station may be overheating, as outlined below.

 

Incorrectly Charging Your Portable Generator

If you find your portable power station is getting very hot when you charge it, then it may be that you are charging it incorrectly. Incorrect charging practices include overcharging your portable power station, charging it in the wrong environment, and undertaking dangerous charging practices like pass-through charging.

 

Charging Your Portable Generator For Too Long

It is crucial not to leave your portable power station charging overnight or for extended periods of time. If you’d like to learn more about the dangers of overcharging your portable power station, you can look at this article entitled “Can I Leave my portable power station Charging Overnight?”

 

Charging in the Wrong Environment

When charging your device, it’s better to do so in a well-ventilated environment. You should also not cover the portable power station while it’s charging.

 

Practicing Pass-Through Charging

Most portable generator that are available on the market do not allow charging and discharging simultaneously. This process is known as pass-through charging.

Pass-through charging refers to the process by which you can use your device, such as a mobile phone, while simultaneously charging it via your portable power station.

Pass-through charging is not recommended. The reason is that the phone’s operating system and the applications place extra demand on the portable power station, which can cause it to overheat.

When it comes to charging your portable power station, it is always wise that you follow the manufacturer’s guidelines.

 

Incorrectly Storing Your Portable Generator

Overheating is often caused by not storing your portable power station correctly, so your portable power station must be stored somewhere that isn’t too hot. Ideally, you need to make sure you keep it in a cool, dry place.

Try to avoid leaving it in direct sunlight or hot places such as the car or on top of your computer. Mobile phone companies, like Apple, recommend that people store their iPhones in temperatures between -4° to 113°F.

While 113°F may seem pretty high, parked cars are known to exceed this temperature, so it’s important not to leave your phone or portable power station in the vehicle.

 

Allowing Your Portable Generator to Short Circuit

Short-circuiting can cause your portable power station to overheat. A short-circuit in a device causes excessive current to flow through the portable power station. This superfluous current, in turn, causes the device to heat up.

To avoid your portable power station from short-circuiting, you need to keep it away from any metal objects like keys, coins, or paper clips. 

 

Damaging Your Portable Generator

 

Your portable power station may start to overheat if it has been damaged in some way. This may have occurred due to dropping the device or by placing any kind of excessive force on it. Any damage to the portable power station can cause its internal structures to become unstable, which, in turn, could cause short-circuiting.

The batteries within the portable power station are actually quite delicate,  so you need to make sure you keep the device safe. It is also advisable not to let children handle portable generator in case they drop them.

If your portable power station is overheating, first try to follow all of the proper guidelines concerning charging time, storage, and limiting any kind of damage to your device. You can also give your portable power station a break to see if it cools down a bit before recommencing charging.

However, if your portable power station is still overheating after trying all of these steps, it may be a manufacturing issue.

 

What to Do if Your portable power station Overheats
