Iris Ohyama is releasing the "Battery Station Bottle Type," a high-capacity battery packed into a body roughly the size of a 660ml plastic water bottle, on June 11. It offers 40,000mAh of capacity and supports up to 65W of charging over USB Type-C and Type-A. The price on the company's official online store, Iris Plaza, is 19,800 yen. With a shape that slips into a backpack side pocket or an ordinary drink holder, it is designed to work as an everyday carry as well as a backup for power outages and disasters.

A Body You Can Carry Like a Water Bottle

The product's defining trait is its size, comparable to a 660ml plastic bottle. It measures roughly 7.2 (W) x 18.0 (H) x 7.2 (D) cm and weighs about 1.15kg. Its near-cylindrical form drops straight into a backpack side pocket or a standard drink holder, so it never takes up much room in a bag and stays light enough to carry in one hand. That matters for a device you bring along every day.

It also carries an IP54 rating for water and dust resistance. IP54 covers protection against water splashes from any direction and against the intrusion of dust to a degree that would interfere with operation. Because you can handle a little rain or dust without worry, it travels comfortably not only on commutes and trips but also as a power source for camping or sleeping in the car.

Long Life Thanks to a Lithium Iron Phosphate Battery

Inside is a lithium iron phosphate (LiFePO4) battery. This type is known for being more thermally stable and longer-lasting than typical lithium-ion cells, and Iris Ohyama highlights its low self-discharge and high durability.

At 40,000mAh, the capacity is more than enough to fully charge a smartphone many times over. Because self-discharge is low, the remaining charge holds up even after the unit sits unused for a while, so it is ready when you need it. It operates even in 0°C conditions and, assuming roughly 200 charges a year, is said to last more than 10 years. Rather than a consumable to be replaced every few years, it is designed as a long-term preparedness item, and that intent fits the product well.

Up to 65W, Three Devices at Once, and Help During Outages and at Night

Output reaches up to 65W, with two USB Type-C ports and one USB Type-A port. It can power up to three devices at once, making it dependable when you want to charge a smartphone, tablet, and laptop together. Using a 65W USB Type-C fast charger, the unit itself recharges in about 2.5 hours, so it is easy to top up even in a short window before heading out.

It also includes an LED light to illuminate your hands during a blackout or at night, and an LCD panel that shows the remaining charge at a glance. The result is a setup that easily plays a dual role: an everyday power bank you carry around, and a simple source of power and light when an outage or disaster strikes.

How You Might Use It

Its drink-holder-friendly shape pairs naturally with keeping it in the car. On a long drive you can charge a smartphone or dashcam, and when sleeping in the car you can run lights or small devices. The size that never struggles to find a spot really pays off here.

At home, it makes sense to stash it in an emergency bag or by the entrance as part of your disaster supplies. With 40,000mAh of capacity, an LED light, and water and dust resistance all in one, it helps secure a way to stay in touch during a prolonged outage and provides light in the dark. Since a single unit serves as both your everyday charger and an emergency power source, you can cut down on the cost and storage space of buying them separately.

Summary

The "Battery Station Bottle Type" is an easy-to-handle, high-capacity battery that fits 40,000mAh and up to 65W output into a body the size of a plastic bottle. Its long-life lithium iron phosphate cell, IP54 water and dust resistance, LED light, and LCD panel suit anyone who wants one device to cover both daily carry and disaster preparedness. It launches June 11 at 19,800 yen on Iris Plaza. For those looking for a long-lasting power source at an approachable price, it is a product worth putting on the shortlist.
