Which mirrors what I have seen Luna themselves post on their own forum. They try to find reliable manufacturers, but the effort is flawed at its heart. There's no fixing that market channel.Worst chargers I’ve owned and the most returned product they sell.
I see I wrote this article in 2019, and by the time I did I had already been using these chargers for over a year. So from 2018 and perhaps a bit before, I have had zero failures with these chargers after 5+ years of daily use. I just put my third one into a bike as an onboard weatherproof charger. All I have to do is plug the bike into the wall and it starts charging. I've already plugged this new bike in at a park pavilion to get some juice while having a snack en route somewhere. And over the years, I've had it save my bacon when something unexpected has happened and I needed a mid-trip charge.
But the real benefit is to never worry about a charger failure due to an inherently superior design, with no moving parts to fail, specifically meant for long term and often-outdoor reliability. Dependable, reliable and adjustable charging is half the battle insofar as battery safety is concerned.
How about a charger – quickly adjustable for voltage and current – that is rated for hundreds of thousands of hours of use before it typically fails?
