The content of the portable power source is a battery called a lithium-ion battery. It's basically like a smartphone or portable battery.
I think you have encountered a case where the battery degrades when you use it on your smartphone. However, it is important to note that it will deteriorate even if it is not used. Even if it is not charged as often as a smartphone, it will slowly deteriorate, although not as quickly as a smartphone.
So how do you make it last longer? The question arises, right?
The basics are the same as for smartphones. However, usage time and charging frequency vary between smartphones and portable power sources. In particular, while smartphones are used nearly all of the time, many people use mobile power in limited ways, such as outdoors or during emergencies.
I would like to explain how to use and care for such portable power supplies. The point is to be a little more careful like a human.
There is one more thing to keep in mind before explaining. The uses and uses listed below are better uses and uses. Depending on the camp and the environment you face in an emergency/emergency, you may not always be able to. Even in such a case it is not a dangerous design that will cause immediate failure or the battery will become unusable so read it without thinking too much that you have to protect it. defend it!
Like humans, Batteries are not good in hot and humid environments!
Portable power sources do not like hot and humid environments. The built-in lithium-ion battery becomes hot when used in a place exposed to direct sunlight, especially in hot weather. Using or exposing it to heat may cause battery deterioration.
Then use it where it is as cool and airy as a human. It is said that lithium-ion batteries work best in environments around 25°C.
Especially when using it outdoors, get close to a portable power source and say, “Wow, that's hot.” If you're in a sweaty environment, move it into the shade.
Similarly, I'm not good at places that are too cold. This is the same as when a person goes below freezing, the whole body becomes stiff and slows down. As with all batteries, not just portable power sources, keep in mind that battery life will be shorter in low-temperature environments.
* Again, the above is an ideal environment only. For example, JVC's portable power supplies can be safely used in environments from -10°C to 40°C.
Even when using it outdoors, avoid hot and humid environment as much as possible and put it in a cool place like shade of tree.
Additional charging is no problem
Primarily on smartphones, it is said to have originated as an urban legend that "additional charging shortens battery life".
In the case of lithium-ion batteries, that is not the case.
Also, as a battery characteristic, you may have heard that "charging before the battery becomes 00% can cause battery life to not deteriorate."
Again, this does not lead to a noticeable performance degradation. Sufficiently speaking, it is a fact that "battery is at its best when at about 40%", but it does not mean that performance is not achieved when the battery level is different.
In addition, there is an entry called "charge count" in the product specifications that uses lithium-ion batteries as portable power sources. For example, if there is "Number of charges: 500 times", how do you count the number of charges? You may wonder.
This charge count does not mean how many times the portable power supply has been charged. This will be done once when the total capacity of the battery actually used (discharged) reaches 100%.
For example, say you have a portable power source with a battery capacity of 100,000 mAh. First charge 100,000 mAh. If you use it at once until the remaining amount is zero, it will be charged once.
Instead, let's say you first use 50,000mAh (50% used) and then charge 50,000mAh. In this case, the number of charges will not be one. Even if I use 30,000mAh (30% usage) on a later occasion and charge it after I get home, the number of charges is still not the same. If you use 20,000mAh (20% usage) on another occasion, the number of charges will be counted as one first charge (50% + 30% + 20% = 100% usage = one charge).
For that reason, don't worry about battery level or how many times you need to charge it, and charge it when it can or should be charged.

Do not use other devices while the mobile power source is charging
If your boss asks you to do it and do this too!
The lithium-ion battery built into the portable power supply supports multitasking, but I'd really like to avoid it.
This means that it is better not to input and output power at the same time. For example, while charging a lithium-ion battery built into a portable power supply, it is used to power household appliances that do not have a battery or to charge other devices with a built-in battery, usually called pin -because.
It is possible, but not recommended. Such usage puts a load on the battery and increases its life.
Similarly, charging a mobile power source with a solar panel while supplying or charging other devices from a mobile power source also places a load on the device.
Keep battery level at 60-80% before storing
Everyone knows that it's not healthy to go to bed when you're full and say "Ah~ I ate too much today~". It is often said that you should finish your dinner a few hours before going to bed. On the other hand, if you continue to sleep in the "I'm hungry" state, you won't be able to eat much.
Also avoid using a portable power source for months of long-term storage with 100% or 0% battery. This is because it accelerates the deterioration of the battery and reduces its performance. Especially long-term storage where the remaining capacity is zero, may not be recharged.
After that, it is often said that the degree of damage of the lithium-ion battery is the least, and the remaining battery life is about 40%.
However, I don't think I'll get a chance to use a portable power supply for a while, so when "keep it at about 40%" the story changes again. This is because about 20% of mobile power supplies are discharged spontaneously in 6 months (half a year). If you keep it with 40% of the money left, it will be 20% after half a year, and at the end of a year, the balance will be zero. This is too little.
In addition, if an emergency such as a power failure occurs during storage, you may not be able to use it because the battery level is too low even though you have a portable power source.
Therefore, we recommend long-term storage at around 60-80%. In this case, even after 6 months, there is still 40 to 60% battery left. The remaining amount is suitable for storage and can be used even in an emergency.
Check at least every six months to make sure you have enough water remaining.
However, a better way is to use a portable power source about once a month. Once there, check the operation, such as the main unit can be charged without problems and power can be supplied to other devices. If you use it regularly and are used to using portable power, you won't have to panic in case of an emergency.

* Do not leave the AC adapter, cigar adapter or solar panel connected when storing portable power.
Leaving them connected will cause the battery to fail quickly because it will be constantly being discharged and charged.

Remove from the box and store in a well-ventilated shade
As mentioned above, devices with built-in lithium-ion batteries as well as portable power sources don't get hot or cold well. It is said that the optimal temperature for storage is around 25°C, so it is the same as the set temperature of the air conditioner. I also want to avoid places with excessive humidity or dust.
In other words, storing in an environment that makes us feel comfortable is also good for preventing battery deterioration. At home, the living room or common room will be the most suitable environment. However, it can be difficult or uncomfortable to keep it in such a place all the time. In that case, it might be better to place it in the entrance or hallway (depending on the environment, so it won't be suitable if the entrance or hallway is hot humid or cold environment).
It is best to store in a cool place, avoid direct sunlight, avoid high temperature and low temperature environment.
Except for the cold season, even the house is prone to heat and humidity. Make sure that the storage location is such an environment.
However, on the contrary, in the cold season of cold regions, it is necessary to prevent the mobile power from being too cold. As noted above, if it is cooled too much, the charging capacity will decrease. When you have to worry about overcooling, it's a good idea to keep it in its packaging.
After purchase, remove from the packaging and store in a cool place. On the contrary, if you store in the cold season of cold regions, you should use packaging materials to ensure that the main unit is not too cold.
As mentioned above, this time we have explained how to use and take care of the portable power supply to prevent speed degradation.
Considering each use environment, intended use and emergency use, it cannot be said that “this should do”. However, keep in mind that portable power supply is not good for the environment and usage is not suitable for everyone to work or rest.
If you feel that "ah, this Portable Power Supply seems to be very painful right now", let's change where to use it, how to use it, and where to store it. By doing so, you will be able to maintain performance for a longer time and use it while feeling convenient.
