Power Dome NX 2485 | A Good Buy?

 No one knows when mother nature, in a fit of anger, will throw us a curve ball in the form of hurricanes, twisters, earthquakes, typhoons, snow blizzards, diluvian rains, etc. Nobody knows either when a car is going to experience a nail or screw-related flat tire, or a dead battery due to leaving the dome light(s) or headlights ON inadvertently. Finally, no one anticipates being stranded in no man’s land with a discharged cell phone.

 While there is nothing you can do to prevent natural disasters, there are, however, plenty you can do in terms of preparedness to lessen the impact of those dreadful occurrences. Your level of preparation will dictate the manner in which you react (positively or negatively) and respond to these unpleasant eventualities.

It can be recharged 3 ways: with the AC Adapter at home, with the DC Adapter in your car, and with a Solar Panel through the Charger Unit Port. How long should you charge the unit? No more than 48 hours (AC charging), no more than 16 hours (DC charging)

  • Jump Start a car
  • Inflate a tire
  • Use the Flashlight and its Hazard Flasher
  • Use the DC to AC Inverter
  • Use the DC Power Port and the USB Power Port
  • Set the Clock and AM/FM Radio
  • Charge the Unit, etc.


12V DC Output

The 12V DC Socket (11Amps max) is more than enough to power most DC Appliances.


Radio: The integrated Digital Radio‘s sleek design, along with its dual speakers, is one of our favorite features. It comes with a cluster of 6 digital buttons: Vol+ Vol- to increase and decrease volume; CH+ CH- for tuning in your favorite AM/FM stations and setting the digital clock; Memory to save and recall preset stations, and to access the clock for setting; AM/FM to tune in preset AM, FM stations or the Clock.

Work Light

The Work Light, a cluster of 9 LED bulbs, is very bright, daylight bright, and the light beam reaches as far as 20 feet.


The Compressor’s 260 PSI is more than enough to inflate a tire, a mattress, a football, etc., in no time.


Audio Output Jack

The conspicuous absence of an Audio Output Jack makes it impossible to listen to the radio within the privacy of a headset. An Audio Output Jack would be appreciated.


One can’t help but acknowledging the beauty of the radio set, and the elegance of its dual speakers. But despite the sleek design, It’s only a matter time (not if, but when) before the digital clock radio controls malfunction, based on our previous experiences with digital radio controls (for the record: the Power Dome NX 2485’s digital controls have not shown any sign of malfunction yet). For that reason – and for that reason alone – we prefer Analog Radios with Tuning Dial and Power Switch/Volume Control Knobs.

Light/Flasher Switch

The juxtaposition of the Light/Flasher Switch next to the Compressor Switch causes a user to mistake one for the other occasionally, especially in darkness. The Light/Flasher Switch should have been located on top of or next to the Work Light for clear and easy access.

Inverter Wattage

The Power Inverter’s total wattage is only 200W. We would have preferred a minimum of 300W to power appliances and electronics requiring over 200W of power.

Work Light

The Work Light does not pivot. A 360-degree pivoting light would have added more functionality to the Work Light.


The Internal Sealed Lead Acid Battery is 12V 14 Amp Hour. We would have preferred a 12V 18 Amp Hour for relative extended use.

USB Power Port

The USB Power Port’s specifications are 5V 500 mA. Most Cell Phones charging requirements are at least 5V 1000 mA (1A). A 5V 1A USB Power Port would have been ideal.


The Analog Voltmeter Gauge and the Analog Compressor Pressure Gauge are not back lit, which makes it a stretch to read either one in near darkness.

Serviceable Parts

According to Wagan Tech, the unit’s only serviceable part is the 25A Fuse. The consumer is advised to take the entire unit to a recycling facility “when the battery has reached the end of its lifetime”. We beg to differ and think that, in addition to the 25A Fuse, the following parts should have been serviceable (replaceable) as well: Internal Sealed Battery, Internal Inverter, and Work Light’s cluster of LEDs. The wholesale discarding of the unit at the end of the battery’s lifetime, based on the product’s ill-conception, is ill-advised in our view.

If the Power Dome NX 2485 were a hybrid (battery/gas) car, would disposal of the entire vehicle, and purchase of a brand new one, be the solution to a battery whose lifetime has reached its end? We think not. The company needs to go back to the drawing board to design a customer-friendlier product. But, in spite of the foregoing observation, we strongly suggest that you follow the company’s recommendations with respect to the method of disposal of the unit for safety’s sake, and to totally disregard our opinion, which carries no weight in the matter. Despite the company’s caution, safety warnings, and method of disposal recommendations, a tinkerer’s inquisitive mind would hardly resist the temptation to tamper with the unit.

Replacement Parts

Despite the company’s advice to discard the unit (Power Dome NX 2485) when its usefulness has reached its end, there are still parts that are replaceable, besides the external 25A fuse:

  • AC Charging Adapter
  • DC Charging Adapter, and
  • Battery (12V 14AH – AA5021)


We’ve only scratched the surface about what the Power Dome NX 2485 has to offer. If you care to explore in depth the breadth of features, specifications, and functionality of the Power Dome NX 2485, buy the unit and read the User’s Manual before you use it .

In light of the pros and cons, should you own this Compact Multipurpose Emergency Power Supply or not? We think the matter calls for a pragmatic decision: it’s better to own one in time of emergency than to do without. And the right time to buy one is now, not in the midst of trials and tribulations (emergency). An ounce of prevention (immediate action) is better than a pound of cure (procrastination). Preemption is better than reaction. Act now! Is the Power Dome NX 2485 a good buy ? We think, based on its practical features and specifications, that it is; although there is plenty of room for improvement.
