Question 1

I’ll be using a 125ah deep cycle battery, could this power a small lightbulb, and perhaps a smalspace heater/fan while charging phones simultaneously?

Accepted Answer

This is an older question but it gets asked a lot so for others I’ll answer.  AC inverters are not well suited to high sustained loads like space heaters.  A typical household space heater will draw around 1500W on “high” and usually around 1000W on “low”.  At “low, or 1000W, for example, you will be placing a roughly 100A load on your battery bank.  If your battery bank could actually sustain 100A while delivering its full rated amp-hour capacity then a 125Ah battery would be 100% depleted within a single hour of running the space heater on its “low” setting!  However, lead acid batteries are subject to the Peukert Effect, which can significantly reduce the accessible capacity of the lead acid battery under high demand loads.  As a result, a typical flooded deep cycle lead acid battery with an amp draw nearly equal to its 20-hour Amp-hour capacity rating (which is normally based upon a C/20, or 20-hour discharge cycle) will typically only be able to deliver about 50% of its claimed Amp-hour capacity, or about 62Ah, at such a high sustained load before the voltage would plummet below the 10.5VDC that represents “100%” depleted and the inverter will go into low voltage shutdown to protect both the battery and itself.  In other words, that 125Ah battery would be effectively dead after just 30 minutes of operation!

One needs an enormous battery bank to sustain a 1000W (1KW) load over an extended period of time.  A similar conundrum exists with running air conditioning, only air conditioning uses less than 1/3rd the power per BTU compares to resistive heating.  If you need emergency heating to keep a room warm, forget the electric space heater and buy a stand-alone propane space heater like a Mr. Heater Big Buddy that is designed for safe indoor operation (with automatic shutdown in low oxygen conditions to prevent carbon monoxide production as well as automatic tip-over shutdown).  You can then heat a reasonable sized room for the cost of no more than a few dollars worth of propane per day during a power outage and you won’t need thousands of dollars worth of batteries that need replacing very 5-8 years!

Question 2

I need to run my cpap machine in my semi, so can this inverter be used while truck is off for my 10 hour break?

Accepted Answer

This is an old question.  But I suggest that, whenever you are trying to size a system, you buy a meter that plugs into the wall between the outlet and the device.

These devices will record the actual wattage that is used.  My daughter's bipap only uses 35 watts.  If she uses it for 8 hours, she needs 280 watt hours.  This is equivalent to 23 amp hours.  I bought her an 135 Ah lithium battery.  If she drains it completely (lithium batteries only) she will get approximately 5+ days of emergency usage.  I bought a battery charger for her, so it is always topped off when an emergency arises.

The device also records surge watts for appliances.  A bipap is constant wattage, so there is no problem there.

But other appliances like freezers can have significant amounts of surge when they cycle.  Be sure to look at the surge wattage of inverters.

Question 3

To operate this inverter with my car, I need alligator clips.  How do I get it with alligator clips?

Accepted Answer

Most of alligator clips can only bear hundreds Watts at max, so we don't provide clips,they could not connect batteries well.
alligator clips are for the smaller inverters only.If your devices are under 600watt, we suggest you choose GIANDEL 600WATT pure sine wave inverter.
