- You want a lighted end or individual outlet switches
What owners like
- Three outlets at the far end save running a second cord or power strip
- Flexible enough to stretch out fully

What it does
A 25 foot, 16 gauge grounded indoor and outdoor extension cord from Jasco's UltraPro line (formerly GE branded) that ends in three grounded outlets.
- Three grounded outlets at the end of the cord, so one cord feeds several devices
- Rated for both indoor and outdoor use
- Vinyl jacket meant to resist moisture, dust and dirt
- Double insulated cord with a one piece molded plug
- U.S. based phone support from Jasco on weekdays
A practical cord for holiday lights, a drill, a radio or yard decor that need three plugs at the far end. At 16 gauge and 13 amps it is a light duty cord, so heaters, compressors and other heavy loads need a 14 or 12 gauge cord instead.

Questions
Can a 16 gauge 25 ft extension cord run a space heater?
It is not a good match. Forum electricians and many safety rules advise plugging heaters straight into the wall, or using a 12 gauge cord at minimum.
How many watts can the UltraPro 36825 handle?
It is rated for 1625 watts (13 amps at 125 volts) in total, shared across all three outlets.
Is the UltraPro 36825 OK outdoors?
Yes, Jasco rates it for indoor and outdoor use. Keep the outlet end out of standing water and inspect the jacket for damage.
Is UltraPro the same as GE?
Both are Jasco brands. This cord was sold as GE UltraPro and is now listed simply as UltraPro.
