Ideal for, cars, trucks, overlanding vehicles, planes, these adapters let you upgrade your 3rd party phone mount with Peak Design's strong, low-profile, easy-to-use SlimLink connection system. It works with a variety of modular 3rd party phone mounting systems—specifically ones that utilize either 1" or 20mm diameter ball-and-socket joints. These 3rd party systems enable an almost infinite range of mounting phone configurations. The Peak Design Ball Mount Adapters upgrade your system with brilliantly fast and secure mounting action for your phone. Charging mounts hold your phone magnetically and provide instant wireless charging. They're suitable for any vehicle with a closed cabin (cars, trucks, planes) and can still handle the gnarliest off-road trails. Charging mounts are also MagSafe compatible. Requires a 3rd party phone mount that utilizes 1" (like RAM) or 20mm (like Offroam, Tackform, 67 Designs) ball-and-socket connection joints (sold separately). Locking mounts require a Peak Design Case or Universal Adapter (sold separately).
