I really wanted to like this charger – it takes up less room, both on a night stand and folded up in a bag while traveling and appears to be cleverly designed – however, after receiving two replacement models, both as faulty as the original, I think it has really poor quality control at best, if not a fundamentally flawed design.The charger works best to worst, in order, on the AirPods Pro, iPhone and then the Apple Watch. The AirPods Pro it always charged without issue. Unfortunately, this is the device I need to charge the least frequently. Overnight, my iPhone would often charge fully if I was charging it alone or just with the Apple Watch, but sometimes it would only charge to 80%-90% percent. If I charged it with another iPhone, neither of them would recharge well during the night, sometimes charging less than halfway despite being on the charger for 8+ hours. The Apple Watch was the worst. Even after being on the charger all night it would never charge to 100%. Though it would sometimes charge to 99%, it would come off of the charger burning hot and drop charge much more quickly throughout the day.I kept notes on the Apple Watch charging for Ampere support that speak to the heart of the problem:Apple Watch with official charger:-charges 55-60% in one hour-fully in ~2 hours-charged 4:45pm Mon, discharged 9:00pm Tues, 28hrs total charge (no workout) (in theater mode from 9:30pm-6am)-charged 7:25am Thurs, discharged 9:30pm Thurs, 14hrs total charge (no workout - 29% charge at 9:30pm)-charged 5:45am Fri, discharged 9:45pm Fri, 16hrs total charge (workout) (no substantial theater mode)Ampere charger:-charges 40-45% in one hours-charges 65% in ~2 hours-charges fully in ? hours-charged 6am Mon, discharged discharged 3pm Monday, 9 hours total charge (workout)-charged 6am Wed, discharged 9:15pm Wednesday, 15:15 hours total charge (workout) (BUT in theater mode from 1pm onwards)The Ampere Unravel charges the Apple Watch much more slowly than its official charger and after charging on it discharges much more quickly, necessitating theater mode in the early afternoon. This is using the Ampere Unravel with both the adapter it comes with and significantly more powerful ones, in case wattage was the issue. It's also charging three different Apple Watches, in case the Apple Watch was the issue. Ampere replaced my Unravel twice and the issue persisted. Afterwards they stopped responding to my support requests. I have a friend who uses an Unravel and he also had to have his replaced for similar issues. I can't tell if he got very lucky that his second charger works fine or I just got very unlucky with having three lemons in a row, but after weeks of testing and, support no longer responding, I have to say I can't trust the product.Beyond these major quality control issues, design issues include the product sample photos on the original funding page showed the iPhone charging in portrait mode, which is not possible and the inability to charge the iPhone and Apple Watch when the Unravel is folded as a triangle, meaning you can't use the device in its smallest footprint in the way I imagine most users would use it nightly. These would be annoying major design oversights, but probably tolerable, if the devices actually charged correctly with the Ampere, but since they don't they are just further issues in a device that looks great conceptually, but does not at all deliver.
