Owltech and DOCOMO release original disaster prevention product 'Sonaeru Jūdenki™' in advance on Makuake: A versatile 3-in-1 charger for home, outdoors, and emergencies

Owltech Co., Ltd. (Headquarters: Ebina City, Kanagawa Prefecture, Representative Director: Tetsuya Yamamoto) in collaboration with NTT DOCOMO, INC. (Headquarters: Chiyoda-ku, Tokyo, President & CEO: Yoshiaki Maeda) has developed an original disaster prevention product, the "Sonaeru Jūdenki™" (Preparing Charger).

DOCOMO will begin advance sales of this product on the support purchase service "Makuake" from 10:00 on Thursday, April 16, 2026.

This product is a versatile 3-in-1 charger that can be used as an AC adapter at home, a mobile battery on the go, and an emergency power supply during a disaster. The main body uses a phosphorescent material so it can be easily found even during a power outage. Furthermore, it clears DOCOMO's strict genuine quality standards, including a safe and secure design that prevents ignition and heat generation.

Main Features of "Sonaeru Jūdenki™"

1. [Uses "Phosphorescent Material"] Because phosphorescent material is used for the main unit, it can be quickly found even during a power outage.

2. [Excellent 3-in-1 Device] Can be used as an emergency power supply during a disaster, an AC adapter at home, and a mobile battery on the go. Since the built-in storage battery is automatically charged, everyday use naturally becomes disaster preparation.

3. [DOCOMO's Safe and Secure Design] To prevent ignition and heat generation accidents, it has cleared DOCOMO's strict safety standards (short-circuit countermeasures, abnormality detection functions, etc.).
