Review: Works Great and Built Well - I bought this to convert a 14-30 charger to a 14-50 plug and it works great, no issues at all and it's built well and I'm not concerned about any electrical faults
Review: Adapts, no issues - No worries about an appliance made for a 30A outlet overloading the 50A outlet. However that does mean a short circuit or overload would make it harder to trip the 50A breaker when that appliance is made with the expectation that it's under a 30A breaker, so be aware of that. Check that the adapter and appliance plug/cord isn't overheating.
