Test Vehicle Battery Level Feature

Although use of your vehicle's cigarette lighter adapter/12-volt DC power outlet to provide power to handheld and/or in-vehicle devices is convenient, it is important to realize that in doing so you are potentially using power that your vehicle battery needs to operate its electrical systems properly. This includes starting your motor. For this reason DC powering/charging is best done while the engine is running, allowing your battery to recharge itself. Charging can be done while the engine is off, but you risk depleting your battery if this is not done carefully. This is where the Wagan EL2537-5's vehicle battery test level functionality comes in. Consisting of a prominent series of LED lights at the top of the unit, it is designed to keep you aware of the affect your DC power charging is having on your vehicle battery. To test the current state of your battery capacity, turn off the engine for ten minutes and check the unit's LEDs. (Socket may not be live with ignition off). The EL2537-5 also allows you to monitor the status of your battery while you are charging devices via DC power outlet.* In either case LED system has a light for each of the following statuses: Low, 12V, Mid and High.

  • 4 lights = good battery
  • 3 lights = normal battery
  • 2 lights = weak battery (possible fault in charging system)
  • 1 light = battery needs charging (possible fault in charging system)
  • No lights = No capacity, replace battery (voltage < 3V) and check your charging system

As a precaution, remove the adapter from your vehicle's 12-volt outlet when not in use. (Some vehicles still provide power to the socket even when the vehicle's power is turned off.)

Key Features

  • Allows your single standard cigarette lighter adapter or other 12-volt DC vehicle power outlet to power multiple accessories simultaneously
  • Provides two 12-volt DC power outlets (provides the full 2A if only 1 USB port is used; if both USB ports are used, then each will provide 1A)
  • Short cylindrical body shape fits snugly into most standard cup holder inserts, ensuring stability near the dashboard
  • Prominent multi-colored LED vehicle battery level indicator light alerts you to the level that your battery is being drained
  • Attached DC power outlet included

The Wagan Twin USB/DC Cup Holder Adapter is a very good value. Considering that I paid the same price for a single USB car lighter adapter, this is a great value. It's conveniently shaped like a cup-holder, with the added benefits of 2 included DC adapters and 2 USB adapters. So far all 4 adapters work perfectly.

This adapter definitely sits lower in my cupholder than what I was expecting. It looks taller in the product picture, but expect it to be just above flush with your cup-holder. If your car has two different sized cupholders, one larger than the other, this unit is designed to fit in the smaller standard size. For me that is the cupholder further from the control panel and closer to my center arm-rest.

The unit has four LED indicator lights so you can judge how many devices can be charged with it. This "Battery Level Indicator" feature is a nice extra, with "HIGH," "MID," "12V" and "LOW" indicators.

The product package indicates this unit works with standard 12V and 24VDC accessories. Apparently there's a fuse inside the unit in the event you over-use it, though I haven't yet had the fuze go on me.

CONSIDERATIONS

There are a few shortcomings to the product, all of which I would consider minor. First of all, the lighter cable is relatively short. That's ok if you are plugging it into the DC outlet on your control panel. Many newer cars also have DC outlets within the arm-rest console storage area. I found that the cord was just barely long enough to reach down into my car's storage compartment and be plugged in. That means for some vehicles, like larger cars and SUVs, it might be too short.

I really like this device. I have Sirius and a GPS so it gives me 2 sockets. The USB power sockets are good for powering or charging my cell phone.
Easy to use - stays where you put it in a cupholder - highly recommended.

Format: Automotive Verified Purchase
2&1/2 inches diameter on the bottom, chamfered
3 inches diameter on the top, also chamfered
2&1/2 inches tall
Cord exits the back of the unit 2 inches from the bottom, no strain relief.
Cord length is 39 inches

Lighter plug is 3&3/4 inches long, including the stiff strain relief.

Nice surface for gripping the plug when pulling out the plug, but for me I wish the plug was smaller or right angle... I'm not going to be unplugging it. Due to the short length of the cable, and the big plug, I directly wired a socket extension cable to my car's accessory wiring to avoid a big plug in my center console... which also frees up my car's socket.

Bright smooth nickel plated contacts all around. Fuse is a standard cylinder type marked 10A, accessed by unscrewing the nipple end of the plug. The + contacts for the round sockets is one solid piece of metal. One philips screw in the middle of the bottom appears to hold the case together, also one phillips holding together the plug.

Subtle blue glow from the base of the round sockets. Not obnoxious bright like the units I used to have.

This is a perfect solution for what I needed, and the unit works well. Like most adapters it takes two hands to remove the plug, however the design allows single handed plugging.

Great purchase, my only regret is padding my order for free shipping with other things. I should have gotten two of these instead :)

This item would be great if it worked, but my USB circuit blew out within a few days of plugging it in, before I even had a chance to use the USB sockets. I smelled burning insulation but didn't associate it with the converter.

I think many (all?) of the folks who are complaining about the LEDs being nonfunctional don't realize that they are reading the charge state of the CAR battery, not the items that are plugged in. If you look at the small instruction sheet included, it says that it's showing the functioning of the car's charge system when the car is running, and the charge on the battery 10 minutes after the car is shut off (but with the starter switch in the 'accessory' position. Quite useful for finding out what kind of shape your battery is in before the cold weather hits, as even a mostly-dead battery will start a car OK in warmer weather. This little item saved me a tow.

At least the 12V sockets still work. I wish I had tried it out when I first got it rather than wait a couple of months - I wasn't able to return it for a refund.

I think I know why many of these are failing. I ordered one a few weeks ago. When I went to install it, yesterday, I noticed it was making a rattling noise. I opened it up, and found a thin metal heat sink loose inside it. This could have easily shorted the system in any number of ways.

This heat sink looks like it was stuck on the bottom of the voltage conversion chip with a tiny tab of foam tape. I'm serious about the bottom; there's a hole in the board under the chip. The sink also covered a large capacitor. The tape adhesion was poor. I'm sure that if the sink weren't already loose, then it would have fallen off within a short period of time. I'm very glad I never plugged it in.

Having looked inside it, I can also say that it looks to me like sketchy work throughout. Most of the solder joints look "cold", and there is quite a bit of flux contamination on the boards.

This was wasted money, even at the gold box price. Unfortunately, I threw away the packaging when I first got it, so can't return it.
