Japanese hardware brand Elecom has introduced the world’s first sodium-ion battery-powered mobile power bank, the DE-C55L-9000BK. This 9000mAh power bank marks a significant shift from traditional lithium-ion batteries, offering a more earth-friendly, safe, and long-lasting alternative.
Unlike conventional power banks, it does not use cobalt or lithium, reducing environmental impact while offering a lower risk of fire and greater peace of mind.
Longer Lifespan and Durability
One of the standout features of the DE-C55L-9000BK is its incredible lifespan of 5,000 charge cycles. This means even with daily use, it can last around 13 years, far exceeding traditional lithium-ion power banks. It is also designed to function in extreme environments, with an operating temperature range from -35°C to 50°C, making it ideal for use in harsh conditions like snowy mountains and deserts.

Fast and Reliable Charging
Equipped with both USB Type-C and USB-A ports, the power bank delivers fast and efficient charging for various devices. The USB-C output provides up to 45W, making it ideal for fast-charging laptops and smartphones, while the USB-A port offers up to 18W, perfect for smaller devices.
When both ports are used simultaneously, the total combined output reaches 20W. A 1800mAh smartphone can be charged approximately 2.9 times, while a 3000mAh smartphone can be charged 1.7 times. It fully charges itself in approximately two hours, making it a convenient choice for everyday use.
Advanced Safety and Smart Features
To ensure safety and performance, the DE-C55L-9000BK comes with Thermal Protection, which continuously monitors and controls temperature 24/7. The LED indicator allows users to easily check battery levels, while the sodium-ion technology reduces the risk of overheating or fire.
Lightweight and Versatile
