Detailed review
It is automatically filtered by electric
When it comes to outdoor water purifiers, the most common type is to attach it to a pouch, water jug, or plastic bottle to purify water, but Greeeshow is an "electric" type that is rare for a water purifier. This is the biggest advantage of Greeeshow's electric portable water filter.
It's very easy to use: just sink the external filter into the water source you want to clean and press the switch. There is no step of fetching water into a pouch or plastic bottle and transferring purified water to another container, so you can simply put the purified water in the container, making it easy to perform water purification work.

Simply submerge an external filter into the water source.
The included tube is approximately 1m long, so you can get water from a place a little away from the water, so there's no need to worry about your shoes getting wet. When intake of water to purify it, it accidentally gets stuck in the water! There's no need to worry about that (I have experience)

By using the included tube, you can perform water purification work even if you don't have it in your hand
By attaching a special tube to the water purification outlet where water comes out after purification, you can also purify water without having to hold it by hand.
A wealth of water source is required to purify water
Water can be purified in places with plenty of water, such as rivers, but in places where the external filters are not submerged in a breeze, water cannot be purified (though it can be done if there is a container that can store water).
Considering these things, this water purifier is more useful for camping near the water than for mountain climbing. I used it for fishing for mountain streams, and was able to purify the water from the river that flows in front of me, ensuring the necessary water.

Purified water is cold and tasty
It's way faster than a manual water purifier
The water purification started with just a button, and it took about 60 seconds to clean the 500ml of water.
Since there is no need to filter water once and then filter water, it can be purified in a shorter time than a manual water purifier. It was convenient because you could quickly prepare water when you were cooking for cooking during your break.
What caught my eye was that the replacement time for filter media is set to 1,000 liters or 6 months. Some manual water purifiers can be used semi-permanently by washing, so compared to this, filter media is changed more frequently and running costs are incurred.
Built-in battery for repeated use
The Greeeshow electric portable water filter has a built-in 2800mAh battery, and can be used repeatedly by charging.
It can be charged by plugging it into a USB port on a computer or other computer using the included cord, so you can charge it and take it out onto the field without having to buy the battery.
You can see the remaining battery level at a glance
Even if it is an electric type, if it is a battery-powered device, you may not know the remaining battery level, so you may have to set up a new battery every time, or if you try to use it, there may be a problem if you don't have a battery, but the built-in battery has an indicator of the remaining battery level, so you can see the remaining battery level at a glance, avoiding any problems.
Because it is battery-powered, it will become unusable if the battery runs out, but if you fully charge it before use, you can use it without any problems if you are camping for 1-2 nights. Incidentally, when I used it for one night, the battery level didn't go down at all.
compact
As you can see from comparing it to a 500ml plastic bottle, the body is compact despite its electric power and is extremely portable. When it comes to mountain climbing or hiking, it may seem like a lot to take it out, but for outdoor activities such as camping, fishing, or playing in the river, I didn't feel stressed about bringing it out.
The dedicated storage case can hold everything you need and carry it with you.
