Cobra CPI 480 400-Watt Power Inverter
Got wiring we wish to energy adult in a car? The Cobra CPI 480 400-Watt Power Inverter ($54.95 list) lets we do usually that—and it’s easier to use than you’d think. It translates low-voltage DC (direct current) battery energy from your car’s cigarette lighter to 115V AC (alternating current) domicile power. It’s ideal for cars, trucks, RVs, tractors, and boats—assuming we get a section that binds up, that is. We had some difficulty with one of a 3 examination units.
Features and Design
Cobra claims a CPI 480 can energy laptops, 13-inch TVs, DVD players, dungeon phones, and video diversion consoles. It’s also able of regulating an electric can opener, electric knife, a blender, and a food processor, and some smaller energy collection like a 7.2V cordless cavalcade horse and a prohibited warp glue gun. For a finish list, check out Cobra’s product page. Short of a x-ray or coffee maker, or anything that generates an scarcely high energy swell on startup, a CPI 480 should broach all a electrical stream we need for many situations.
Design-wise, a Cobra CPI 480 is a brick. That’s okay, since it doesn’t need to be pocketable—just portable. It measures 6.5 by 4.2 by 2.6 inches (HWD) and weighs dual pounds. It’s done of a brew of aluminum and black plastic, and feels solidly constructed. It facilities dual apart AC outlets on a back, and a USB pier for charging a phone, iPod, or other little device. There are semi-circle indents nearby all 4 corners, that let we mountain a CPI 480 to a tough aspect inside your car regulating 4 screws, nonetheless zero are enclosed in a box.
A two-foot DC cord connects a CPI 480 to your vehicle’s energy jack. Although a CPI 480 is rated for 400 watts, and can hoop brief peaks of adult to 800 watts, it usually supports adult to 150 watts when plugged into a cigarette lighter jack. For aloft loads, Cobra includes a span of two-foot, direct-to-battery, 12-gauge cables.
Performance and Conclusions
As partial of a Fastest Mobile Networks 2012 project, we tested 3 Cobra CPI 480s. We used any one to energy 8 dungeon phones simultaneously, all of that sat in a behind of 3 2013 Ford Taurus sedans. To do this, we used dual Power Squids, any with 4 dungeon phones attached, and afterwards plugged any Squid into one of a AC jacks on a CPI 480. Then we plugged a CPI 480 into possibly of a Taurus SHO’s appendage energy outlets, depending on what we were doing (there’s one in a front and one in a behind seat). The sum bucket from a phones worked out to about 100 watts.
The CPI 480 facilities dual LEDs: A immature one indicating solid power, and a red one that lights adult underneath overkill conditions. During stream overload, a red light will blink invariably before a section shuts down. Under DC submit voltage overload, a light turns on and a section shuts down immediately, though it will keep checking to see if there’s adequate voltage to start adult again.
Unfortunately, one of a 3 CPI 480s unsuccessful after usually dual days. The one we was regulating began sounding a high-pitched alarm. First, it did that a few times with a phones plugged into it. But eventually, it would do that all on a own, with zero plugged in during all, and within 15 seconds of powering it on. In addition, while in use, a little fan on a behind side of a section kept powering adult and down, roughly like clockwork. Every 20 seconds or so, I’d hear a whirr for a few seconds, and afterwards it would stop. Other times during a day, it didn’t do that during all. Our other dual CPI 480s in a margin worked flawlessly, and a deputy Enercell 350-watt section we bought from Radio Shack ran a fan a whole time, though also valid 100 percent reliable.
While a Cobra CPI 480 lists for $54.95, I’ve seen it on Amazon for as low as $26. That’s a flattering good cost for something so useful. That said, a inauspicious disaster within usually dual days discontinued my certainty in a product. That creates it tough to recommend, during slightest but a gift that we buy it from a store with a magnanimous sell policy, in box we get a poor section out of a box. With that caveat, a CPI 480 does a pursuit it’s asked to do—as prolonged as we get a good one.
