For this design phase, our challenge was to incorporate technology while respecting the French know-how according to the tradition of leather goods.
The whole technical aspect of this project resided in the integration of the technological module into the wallet while respecting the grained leather of the House of Lancel in order to ensure an aesthetic rendering that testifies to the complementary know-how of the brand.
To achieve this, we applied a leather cladding on the casing that hosts the battery and added perforations that reveal light visual cues. These marks help to know the remaining percentage of battery in the module. Then, we drew a flat edge on which we applied a slice dye so we could sew the module to the wallet, as if it were any other element.
These wallets are embedding a lithium-ion battery with a 2200mAh capacity and they are able to charge every types of smartphones (iPhone and Android) by using different wired adapters. We decided to use a USB-C port because it allows IN and OUT energy transfer. This way, only one port is enough to recharge the wallet and the smartphones.
