1.0 out of 5 starsCauses Reversed Polarity - Creates a Danger of Shock and Jeapardizes your Gear
Reviewed in the United States on May 27, 2019
When these adapters are used with a standard three prong US Type C plug they create a condition called "reversed polarity". In essence, they connect the prong that expects power with the outlet receptacle that provides neutral, and connect the prong that expects neutral with the outlet receptacle that is hot.
Almost all contemporary equipment will still work when it encounters this condition, but not all, and not without risks. A quick internet search will explain. The risks include fire, damage to your equipment, and electrocution.
Whats more, if you use this adapter to connect a surge suppressor the surge suppressor will not be able to do its job. This can be easily verified: the "wiring fault" LED will light up. Power surges are common in Brazil, and it was important enough to me to protect against them that I brought good ones with me from the US. Too bad though: when they are used with these Ceptics adapters the surge suppressors won't work.
You can verify these adapters cause reversed polarity with a multimeter / fluke. Plug one of these adapters into a properly wired Brazilian type N outlet (one that is grounded and does not suffer from reversed polarity itself) and check which receptacle provides power and which provides neutral. They will be reversed!
All of this was caused by the improper placement of the ground pin. Move it to the other side of the imaginary line that connects the two other pins, and everything would be fine.
I liked this adapter until I realized its fatal flaw. Everyone who reviewed this adapter positively must not have noticed it yet. They had better hope they never will.
These products are unsafe and should be taken off the market!
