Question: is this compatible with 220v outlet?
Document: Not sure why but they won't fit into the outlet ? Prongs are too big I guess. Not worth sending back.
These will adapt a 3 prong plug to an ungrounded outlet. They are a bit more fiddly then the older style. Guess I just expected a bit more for the price, name & description.
Used these in Guatemala during a ten-day trip. Worked beautifully with all my chargers, even my laptop cord! Only issue was some sparking that may have been an outlet issue. Keeping these for future use - well worth the price!
They do the needful. Two things to be aware of: First, you'll probably only be able to get one of these to fit on a double wall outlet, and second, on some older American outlets (pre-1960s) the center screw will be tough to reach, and will require a little extra care to avoid cracking some of the more fragile outlet faceplates.
These work just fine, but have a fairly significant downside. When plugged into our outlet (it may be different in newer outlets) and a heavier cord is plugged into them they have a tendency to droop or wiggle slightly out of the outlet, making it very easy to lose power. Once, I accidentally bumped it and it fell out completely shutting off my computer. Thank you, Autosave.Still worth purchasing, but be aware of their dark, droopy side and plan accordingly.Hope you find this helpful.
this is exactly what I needed and the price was spot on and competitive + Coleman Cable is a reputable company that produces a line of electrical products and everything I own by them works as they should. Can't complain this is a product that is efficient and simply put gets the job done and at a really great value.
have used these for my computer/video game area...these fit snugly into any extension cord and gets the job done..its a no brainer..well worth having a few of these around on hand.
Would give 5 stars but these adapters are REALLY hard to remove from the original plug; they do get the job done though.
Works. The in part is kind of tight and the prongs are a bit too small for our living room outlets.
Works like a charm. Needed these lil guys due to the old apartment me and my roommates are renting. The outlets have not been updated since it was built in the 50s. Hasn't caused me or my pals any problems. Liked it so much, we have 3 pairs of em!
Answer: yes
