Mobile Ball Mount Adapter with Peak SlimLink - Charging, 20mm Ball
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).
Our Review
Peak Design Mobile Ball Mount Adapter (SlimLink, Charging) — Mobile Office Upgrade for the Car-Based Remote Worker
The gist: Adds SlimLink™ magnetic-mechanical quick-swap phone mounting — with wireless charging — to any 20mm ball mount system, turning your vehicle into a more capable mobile workspace.
- Wireless charging keeps you live: Qi2/MagSafe-compatible charging means your navigation app, Slack, and call apps never die mid-commute or client drive.
- One-button release: Press to detach the phone instantly — no re-docking fuss between the car, a client meeting, and back.
- 24-position adjustable arm: Machined aluminum rotates and locks — set once for your exact sight-line so calls and maps are always glanceable without head-craning.
- Vibration isolation: Silicone dampener cushions road vibration — reduces jitter on video call thumbnails or phone-as-monitor setups during stop-and-go traffic.
Peak Design’s official specs confirm compatibility with Offroam, Tackform, 67 Designs, and RAM 20mm ball mount systems — so it integrates into an existing rig rather than replacing it entirely.
Best for: Remote workers and field professionals who spend significant time in vehicles and want seamless, charged phone access. Skip it if: You don’t own a Peak Design Case or Universal Adapter (required for the locking function, sold separately) — without them, this adapter is non-functional. Check the current price before buying.
