That old thread is closed but to continue it.
The MK ones *sound* like they have good safety features –
– will charge a single device at 2A,
– if something pulls over 2A enters a current limiting safety mode
– protected against overload or short on USB outlets
I’ve not seen similar spec claims for any others. I reckon his device or cable were definitely the issue. I was in the Apple Store the other day getting a new battery in my phone. Sat next to someone who was there with an apple laptop charger who’d had the cable burn off it’s outer insulation – middle of an unwound cable with no signs of damage otherwise. Luckily she’d been using it at the time so noticed straight away.
