- The Kuxia S3 is one of the first semi-solid state powerbanks
- That makes them safer than lithium-ion and means they should wear out more slowly.
- It also has a kickstand, a display, and is Qi2.2 compatible.
Kuxia may not be a company you are familiar with, but if you are looking for one of the best power banks, their latest product could be exactly what you are looking for.
The company just announced the Kuxia S3, a 10,000 mAh power bank that the company claims has enough capacity to nearly double the battery life of an iPhone. But beyond its high capacity, this model has several other things going for it.
The main one is that it uses semi-solid state batteries, which are theoretically much safer than the lithium-ion ones you’ll find in other power banks. We’ve recently seen some power banks, like certain Anker models, recalled for being a fire hazard, so that’s certainly a big potential plus.
Unlike traditional batteries, semi-solid state batteries sit between a liquid and a solid, and instead use a gel-like electrolyte substance. This means they also typically last much longer before starting to degrade: a typical power bank’s battery will start to degrade after around 300 to 500 charge cycles, but Kuxia’s should be able to maintain more than 80% of its capacity for up to at least 1,000 charges.
Charge your phone quickly
Beyond its semi-solid state credentials, another advantage of the Kuxia S3 is that it supports Qi2.2, meaning you can charge your phone wirelessly at up to 25W, instead of Qi2’s 15W.
Additionally, it is MagSafe compatible and features a stand, a small screen to show the remaining battery level and charging status, and a built-in cable to charge other devices via USB-C (up to 35W).
All of this makes the Kuxia S3 quite heavy at 245g, but it has 18 built-in magnets, to at least ensure it sticks firmly to your phone. For reference, the previous model (the Kuxia S2) weighs only 145g, but it also has only 5000mAh, has no support, and is limited to Qi2.
In any case, the Kuxia S3 is quite expensive compared to its lithium-ion rivals, priced at $149.98 / £116 / AU$230, but there’s a big launch discount, temporarily dropping it to $68.99 / £54 / AU$106. So if you like the sound of the Kuxia S3, you might want to pick one up soon.
