Accessory maker Elecom has announced what it’s claiming to be the first consumer-ready power bank that uses a #sodium-#ion battery instead of a lithium-ion one.
In addition to being more environmentally friendly to manufacture,
the 9,000mAh Na Plus can be used in extreme temperatures with less risk of overheating,
and has — Elecom claims — a lifespan of almost 5,000 charges.
Even if you’re recharging it every single day, after 13 years it should still be providing power.
Sodium-ion battery technology is new compared to lithium-ion tech, and production capacities haven’t reached the level of lithium-ion batteries.
So while a little deal-hunting can get you a basic 10,000mAh lithium-ion power bank from companies like Anker for less than $20, the Na Plus is debuting in Japan (in black and light gray color options) for 9,980 yen, or around $67.
Elecom hasn’t yet announced a wider rollout
