For iPhone & Co.: Semi-Solid-State Batteries with Qi2.2 and up to 10,000 mAh
Zens has two new external batteries for smartphones in its lineup, which are said to be less bulky thanks to semi-solid-state technology.

News from Zens: The Dutch specialist for Qi and MagSafe charging stations is expanding its business with power banks. In addition to regular variants with conventional lithium-ion batteries, which are currently on sale at the company on sale, there will also be so-called semi-solid-state batteries in the future. This is a modified battery architecture that is said to be less susceptible to fires (thermal runaway), physical shocks/impacts, and temperature changes, among other things. The overall battery life is also said to increase. The overall weight and cell size are also decreasing.
Combination against Shocks and Temperature Fluctuations
The technology combines processes from classic lithium-ion batteries with a liquid electrolyte material with a fully solid battery chemistry. This results in a hybrid material from solid and liquid states, which is intended to combine the advantages of solid-state technology (especially its stability compared to liquid electrolyte materials) with the cost-effective production of conventional batteries. However, tests will have to show what this means in practice.

Zens promises that its semi-solid-state power banks will offer more charging cycles than lithium-ion cells, but does not provide any details. There will be two variants that can currently be pre-ordered: The charging speed is a maximum of 25 watts (iPhone 16 or newer), and 15 watts for older iPhones and compatible Android devices.
Two Variants with 5000 and 10,000 mAh
The 5000 mAh variant is 8 mm thin (slightly thicker than Apple's MagSafe battery for the iPhone Air, which has less mAh), and the 10,000 mAh variant is 14 mm thin. Up to two devices can be charged simultaneously. Power passthrough also allows charging the power bank first and then the iPhone (or vice versa).
It initially remained unclear whether the battery would work with the iPhone Air, which has a special arrangement of the MagSafe area due to the camera platform. The iPhone 17 will be supported in all variants, as will all other iPhones from iPhone 12 onwards (see above). The prices are 60 and 80 euros respectively. Delivery is scheduled to start at the end of March (5000 mAh) and the beginning of April (10,000 mAh) respectively. The weight of both models remains unclear – Zens only mentions the value of 122 g here, but this probably only applies to the 5000 mAh variant.
