NOTICE Please refer to the information below when purchasing a battery remaining indicator! 

※ Battery remaining indicator available for our own battery models

Among our battery models, those with a battery remaining meter port (air terminal) can be used.

Please note that products without aviation terminals cannot use the battery level indicator. 

You can use it by simply plugging it into the aviation jack without the hassle of carrying a heavy power bank. 

The battery remaining indicator (BATTERY COULOMETER) was developed to allow you to enjoy car camping easily!
