World's first sodium-ion power bank

Japanese company Elecom has just launched the world's first power bank using sodium-ion battery technology.

This power bank not only stands out for its frost and fire resistance, but also overcomes the limitations of popular lithium-ion power banks today. Notably, each customer is only allowed to buy a maximum of 3 chargers from Elecom due to limited product quantity.

Advantages of sodium-ion power banks

Switching to sodium-ion instead of lithium-ion in batteries promises to bring many economic benefits thanks to the abundant supply of sodium on Earth , while lithium-ion reserves are running out. Moreover, sodium-ion batteries are safer when burned and do not have the risk of explosion like lithium-ion batteries. In particular, sodium does not pollute the environment, while lithium is difficult to dispose of.

Elecom's power bank has a capacity of 9,000 mAh, weighs 350 grams and measures 87 x 31 x 106 mm. The device provides 45 W of power when charging via the USB-C PD port and 18 W via the USB-A port, with a charging capacity of up to 5,000 cycles, surpassing existing lithium batteries on the market.

The DE-C55L-9000BK and DE-C55L-9000LGY models come in black and light gray, respectively. The price of these power banks is around $68 in Japan, which is higher than similar devices using lithium-ion batteries. However, the highlight of Elecom's power banks is the safety of sodium-ion batteries, which can operate effectively even in temperatures as low as -35°C.
