Testimonials
What Our Customers Say
Trusted on the Trail, the Track, and the Course
"No more dead battery anxiety." I used to constantly stress about my Garmin dying during my long training rides and trail runs. This charger completely solved that. Being able to charge the watch while keeping it on my wrist is amazing. The connection stays perfectly secure even while I'm moving. I don't leave for a long weekend without it.
"A lifesaver for ultra-endurance races." I bought this specifically because it allows me to charge my Garmin while it's still on my wrist. I used it during a 100-mile trail race, and it worked flawlessly. The connection stayed perfectly secure while I was running. Absolute game changer.
"Finally, a charger built for endurance athletes." As a marathon runner, the last thing I want to worry about before a long Sunday run is whether my Garmin is fully charged. This unit is compact, rugged, and handles my training schedule perfectly. It doesn't disconnect and charges fast. Best investment I've made for my gear this year.
Frequently Asked Questions
Questions & Answers
We've collated the most common queries from our user base.
LongRun is designed to work with most Garmin sport and outdoor models that charge via USB on the right or left side of the watch. If your Garmin uses a standard charging cable (not a proprietary cradle or dock), LongRun is likely compatible. Not sure? Just check the charging port - or reach out to our team and we’ll confirm for you.
Yes. That’s exactly what LongRun was designed for. Unlike bulky battery packs, LongRun integrates with your wrist strap, allowing you to power your watch while running, hiking, biking, or commuting - no need to stop or hold anything.
Not at all. LongRun weighs just 0.85 oz - about the same as two quarters, and was engineered to stay flush against your wrist. Most users report forgetting it’s even there.
LongRun delivers steady, efficient charging while you’re in motion — fast enough to offset drain and increase battery percentage, even during use. It’s also ideal for pre-run top-offs if you need a quick boost.
LongRun is fully waterproof and ruggedized for endurance athletes and adventurers. Whether it’s sweat, storms, or alpine grit, this charger is built to survive wherever you take it.
Yes. LongRun features a secure locking strap system that keeps it in place during sprints, climbs, and uneven trails. No slipping, shifting, or bouncing — just reliable power.
LongRun provides enough power to fully recharge most Garmin watches once.
During charging, Garmin pauses heart rate monitoring, this is standard Garmin behavior, not a LongRun limitation. GPS tracking continues uninterrupted throughout
We provide a proprietary 1-meter magnetic charging cable in the box. It snaps effortlessly onto the LongRun to top it up before your next big event. When you're out on the trail, the LongRun clips directly onto your Garmin - no cables required while moving.
We offer a 30-day risk-free guarantee. If LongRun doesn’t perform the way you need it to, just send it back - no questions asked. Your trust matters more than a transaction.
No! But we're working on a version of LongRun Pro for Apple Watch users! Coming Soon!
