Accessory maker Elecom has launched what it claims to be the world’s first consumer-ready power bank that uses a sodium-ion battery, which is more environmentally friendly to manufacture than lithium-ion batteries.
It is also safer to use in extreme temperature conditions with a risk of overheating, according to Elecom.
The Na Plus power bank has a 9,000mAh battery capacity, can be recharged nearly 5,000 times, and has a lifespan of 13 years.
It is launching in Japan for €67 in black and light grey colour options, but there is no word yet on wider availability.
However, sodium-ion batteries are larger and heavier than lithium-ion batteries, which may limit their use.
