TRGR® Introduces “BATTERY SHIELD BAG” for Enhanced Lithium-Ion Battery Safety
BO-WORLD Co., Ltd., through its TRGR® brand, is set to launch the “BATTERY SHIELD BAG TRGR®”, a new product focused on the safety of essential mobile batteries in modern society. This innovative bag is designed to offer peace of mind for everyday use, with crowdfunding scheduled to begin on CAMPFIRE from July 24, 2026.

Product Concept: Fire-resistant × Waterproof × Refined
The “BATTERY SHIELD BAG TRGR®” embodies the concept of “carrying peace of mind in daily life.” It integrates safety and design, protecting valuables from potential risks while blending naturally into everyday styles. The bag is designed to organize digital devices such as smartphones, mobile batteries, and PCs, and is equipped with features to prepare for unexpected troubles like thermal runaway of lithium-ion batteries or sudden rain. A utility model application for the bag’s fire-resistant structure has been filed.
Development Background
Recent years have seen reports of smoke and fire incidents involving lithium-ion battery products, including mobile batteries, in public spaces such as airplanes, trains, stations, and vehicles. While indispensable for smartphones and mobile devices, lithium-ion batteries carry risks such as thermal runaway and deterioration over time. Traditional fire-resistant cases and protective gear often prioritize safety to the extent of being heavy, bulky, or incompatible with daily styles.
The “BATTERY SHIELD BAG TRGR®” was developed to provide both high protective performance for valuables and a sophisticated design that encourages daily use. In addition to serving as a portable bag for outings, it includes a fire-resistant pouch (one piece) made of flame-retardant material, making it suitable for storing lithium-ion battery-related products at home or work, adding a layer of security to daily life.
Target Audience
The product targets all individuals leading a mobile lifestyle, from daily commuters to business professionals and frequent travelers.
