【Emergency Battery】Low fire risk! A disposable “card-type” smartphone battery

Sudden disasters and unexpected troubles. In such times, the smartphone at hand becomes the only lifeline connecting you to family and information. To reduce the regret of "If only I could charge it here and now...", the “amulet battery” that can be tucked away in your wallet was born.

A disposable battery that can be used just by inserting it without needing to charge!

In Japan, there are disasters like earthquakes, heavy rains, typhoons, and power outages that can happen at any time, making it a constant concern in daily life. To feel secure in emergencies, what is first needed is a smartphone to obtain information and communicate with family and those around you. However, if the crucial battery runs out, it can’t fulfill that role.

A credit card...? You might think. The "Battarix Power Card" is an emergency card-shaped smartphone battery with an ultra-thin design of just 3.8 mm in thickness. It is almost the same size as a business card or a credit card, weighing only about 27g, which is roughly the weight of three 500-yen coins. It can be kept in your wallet, pass case, or smartphone case, preventing situations where you find yourself without a mobile battery when you need it most.

Pre-charged disposable type (pre-charge) means that there is no need for prior charging like a mobile battery, and in an emergency, you just need to plug it into your smartphone to start charging immediately. With both a Lightning port and a USB-C port built into the body, it is compatible with both iPhone and Android. There’s no need to prepare a cable, and it’s designed to be intuitive enough for small children and the elderly to use.

The capacity is 1600mAh. It cannot fully charge a smartphone, but depending on the model and usage conditions, you can expect about a 10-40% charge recovery. It has enough capacity to support truly necessary actions in emergencies, such as contacting family members for safety, making emergency calls, checking your current location with map apps, and conducting basic operations for returning home or calling for rescue.

The battery uses lithium manganese batteries (Li-MnO₂), which have a low risk of ignition or explosion. Due to its structure, which does not allow for repeated charging, there is less concern about degradation or accidents from overcharging, making it suitable for disaster preparedness supplies. Furthermore, it has obtained UN38.3 certification, which meets international transportation safety standards. It can be carried on both domestic and international flights, making it a reliable companion for travel or business trips. It’s lightweight, compact, and easy to hold for all ages, making it like a protective charm.
