Compact and Lightweight Portable Power Supply Now Available

Sanwa Supply Unveils New Portable Power Supply



Sanwa Supply, based in Okayama, Japan, has launched a versatile portable power supply, model 700-BTL057, available on their direct sales website, Sanwa Direct. This product, designed for everyday use, combines compact portability with a powerful output suitable for various applications.

Compact Design for Everyday Use



One of the standout features of the 700-BTL057 is its lightweight design, allowing users to carry it around easily, even with one hand. Weighing in at a fraction of the size of traditional power supplies, this product is particularly appealing for women and those who prioritize convenience. With a capacity of 192Wh and an output of up to 300W, it is perfect for outdoor adventures, emergency situations, or daily home use. Users can now have peace of mind knowing they have a reliable source of power available whenever they need it.

Reliable Power Supply for Small Appliances



The power supply features two AC output ports, accommodating devices that require up to 300W. This means users can easily connect small appliances like fans or cooking devices, making it a practical solution for camping or during power outages. What’s more, it delivers stable power with pure sine wave output, providing the same level of quality as a standard household socket, ensuring the safe and efficient operation of connected devices.

Long-lasting Lithium Iron Phosphate Battery



Equipped with a lithium iron phosphate battery, the 700-BTL057 promises longevity through approximately 3000 charge cycles. This durability is primarily due to its advanced Battery Management System (BMS), which protects against overcharging and deep discharging, making it a dependable companion for both everyday and emergency usage. Users can enjoy the convenience of a long-lasting power source without the worry of regular replacements.

Fast Charging with USB-Type C



In addition to AC ports, the portable power supply empowers users through its USB capabilities. It features three USB ports, including a Type-C output that supports rapid charging of laptops and tablets. Simultaneously, it allows for quick charging of other devices like smartphones via its USB-A ports. A car charger cable is included, making it easy to stay powered up on the move.

Integrated LED Light for Added Functionality



For added safety and convenience, the device comes with an integrated LED light. This feature is especially useful during power outages or while camping at night. Whether as an emergency light or for evening strolls in the dark, it supports outdoor activities while ensuring users feel safe and comfortable. The portable power supply perfectly merges functionality with enjoyment, enhancing both preparation and adventure experiences.
