Highly recommend a Giandel extension cord for the 300W inverter:https://www.amazon.com/dp/B07WK86T7K
More details and tips:
If the rated power of AC devices exceed 150W, please double check your car cigarette socket,as most vehicles 12V ports are rated and fused 15A for 150W max.
Connect the inverter to a 12V car cigarette socket and plug your AC devices into the inverter
Please do not leave the power inverter in the ON position while your car is off.
Do not put the inverter into sunlight directly, keep it in cool and dry environment
Don’t use the inverter with a product that draws a higher wattage the inverter can provide,as this may cause damage to the inverter and product

To pull over 100 watts you will likely need to use a booster cable clamped onto the lighter plug. At first I thought it was not good because it would beep with 160w of load and stop. however it will sense the lack of current and cut out . It didn't blow the cig lighter fuse.I re tested it using a battery fully charged and a set of booster cables and I could pull 250watts from it no problem.Yes it runs induction loads such as motors.

The best thing is the USB outlets, on mine are fast charging and the switch for the plug ins, does not have to be on. I work out in the oilfield and it is the best and most valuable thing I have got so far!! Highly recommended.

This is my third Giandel inverter purchase and I have been happy with all 3. My previous purchases were the 2200W sine wave inverter and the previous version of this 300W sine wave inverter. Since I used to design inverters and UPS systems, I was intrigued how they got the cost down for a sine wave inverter. The PWM control and output filter add significant cost over a modified sine / step wave inverter. There are not many loads that a step wave is safe to use, with motor and magnetic / transformer type loads being the worst. Also, any electronic load that has EMI filtering (computer, TV, electronic blower for HVAC, etc.) can damage the EMI filter in the load. I do not believe most people should risk using a modified sine inverter. You are getting what you pay for, and can damage some of your appliances and even cause fire.The manual specs that interested me are:Continuous 300WSurge power 400W +/- 100W (can be as low as 300W!)I measured only 506mA of current without any load. That is only about 6W at idle.When I first tested this, I found I could easily cause the under voltage alarm to trip, which is latching. You have to cycle the power switch on the unit to reset the alarm. What I found was as expected: any voltage drops when the inverter is starting or running will help cause the UV alarm. These could be: poor battery, wiring that is too small, small wiring to the cigarette lighter socket, fuse voltage drops, and poorly seated cigarette lighter plug. So if the UV alarm trips, check these first before blaming the inverter. Just like with me, it is likely to be user error.My only negative on this is that it does not have UL or ETL safety marks, which indicates that the product has been safety certified for electric shock and fire. There are a ton of products coming from Asia that are poorly made and do not have these safety marks, so when I end up with one, I check it out before using. Which I did for voltage spacing. :)They used reasonable safety spacings, and I noticed that they have good designs for EMI noise as well. The ground prongs are left open on the standard 120V outlets (NEMA 15-20), so be aware that the ground is open. This is typically fine with most appliances but consider it only truly safe for double insulated appliances. Note that this wiring trick is common on many low power inverters, but not on UL/ETL inverters or UPS systems!Overall, I found this a good buy and safe to use with my CPAP machine - with a floating battery and double insulated CPAP device.

I tested this inverter by connecting battery clamps to the cig lighter plug. The test leads and the input wire feeding the inverter got warm so there was wiring loss, but this heat was outside the inverter. The warm wires indicate they are too small, so if you plan to operate near full load, cut the wires near the inverter and crimp on wires that can handle 30A and keep them short to minimize voltage drop and power loss.I estimated the efficiency using the BMS readout from a lithium battery, comparing to the reading from a Kill a Watt meter (not super accurate and I wish my test equipment were better). I got fairly flat efficiency of 75% to 80% while the load was varied from 40W to 300W. At full load there would be 75W of heat generated and the inverter needs the fan to keep cool. With the fan the case never got very warm during testing even at full load.The fan is fairly quiet and turns on somewhere between 45W and 140W. It's nice that the fan is completely off with a small load.The inverter has a standby current of about 0.5A (or 6W). The input current is about 2.5mA with the inverter turned off and nothing plugged into the USB socket.The inverter features a soft start and appears to be well constructed internally. More gluing down of components - like with silicone RTV - would be a good idea if it's going to experience a lot of vibration. If the inverter starts beeping and shutting off due to low input voltage, check for a weak battery, poor wiring connections, thin input wires and/or long input wires.If the inverter reached an 85% efficiency I would have rated it 5 stars. I think the manufacturer was too optimistic with the 91% peak rating, which is what I wanted.
