MOTTERU Introduces 20,000mAh Semi-Solid State Mobile Battery for Enhanced Safety
MOTTERU Co., Ltd. announced the launch of a new 20,000mAh large-capacity mobile battery, incorporating a semi-solid state battery for significantly reduced fire risk. This model became available for purchase on May 25th (Monday) at physical stores and online marketplaces.
The “Semi-Solid Mobile Battery 20,000mAh PD65W with USB-C Cable (MOT-MBSS20001)” aims to provide a safer and more reliable charging experience.
Key Features
Enhanced Safety with Semi-Solid State Battery
The new mobile battery utilizes a semi-solid state battery, which offers increased resistance to impact and heat compared to conventional lithium-ion polymer batteries. Internal testing, including nail penetration tests, confirmed no smoke or ignition, substantially lowering the risk of fire. This design addresses concerns about mobile battery safety during extended use or accidental impact, making it suitable for various applications, including powering fan-equipped clothing, baby products, and pet cooling devices.
Extended Lifespan and Wide Operating Temperature Range
The battery boasts a lifespan of over 2,000 charge cycles, approximately four times longer than traditional lithium-ion polymer batteries (which typically last 400-500 cycles). This longevity contributes to a more sustainable product. Furthermore, the battery operates reliably in extreme temperatures, from -20°C to 60°C, making it suitable for use in diverse environments such as hot car interiors during summer or cold outdoor settings in winter.
High Capacity and Fast Charging for Multiple Devices
With a 20,000mAh capacity and support for up to 65W Power Delivery (PD) output, this mobile battery can charge smartphones approximately four times, and is also capable of charging tablets and notebook PCs like MacBooks. It features two USB-C ports and one USB-A port, allowing for simultaneous charging of up to three devices, from notebooks to earphones. This makes it a versatile power source for travel, business trips, events, or as an emergency backup during power outages or disasters.
Convenient Features and Included Accessories
The battery includes a remaining charge display function and a multi-protection system for safe use, covering overcharge, over-discharge, and short-circuit protection. It is also PSE compliant. Accessories include a 240W USB-C to USB-C silicone cable (approx. 50cm) and a dedicated pouch to protect the mobile battery during transport. The product is available in Smoky Black.
MOTTERU Battery Recycling Service
MOTTERU offers a free recycling program for its used mobile batteries, treating them as resources rather than waste. Through partnered facilities with high-standard heat treatment and recycling technology, batteries are safely neutralized and re-resourced. Customers participating in the recycling program receive a discount coupon for MOTTERU’s official online shops (Rakuten, Amazon, Yahoo).
