Review: Fits the need. - I've seen Giandel inverters on desertcart for a while now. They always seem to be well received and well reviewed, but I haven't had the need to buy a new inverter until recently. I was making due with some older modified sine wave inverters and they were doing the task well enough. So this one was bought to replace one I let the smoke out of. Honestly, i was looking more for an inverter to fit within a specific cubby in my battery box. I wasn't looking for performance per se, just size. This Giandel 300w fits the cubby perfectly so points for form factor. The performance, yeah I lucked out on that. For performance, its top notch. I am happy with it as it does what I intend for it to do - power smaller loads such as my laptop / mobile office or charge my cordless tool batteries when away from the house. It does the job effortlessly. There isn't much to say. It does what it is supposed to do, and that leaves for a less than thrilling review. Would i recommend, I absolutely do. Small quirk for an honest review to be complete.... it seems like this inverter will do a full power draw when you power it on. Self test i assume. When it does this test, it goes to town I guess. When I first plugged it in to verify it worked, it blew the 15 amp fuse I had it on. Well yeah, it'll do that you say. Yes it does, under load. I was expecting it to just turn on and sit there until loaded, but it seems to pull heavy current for that apparent self test. properly rated fuse (same as the fuse in the inverter) fixes this. Just a thought to consider.
Review: Proformed well but chasis is a little misaligned. - performance: I set this up running off two diesel car batteries using a 16awg adapter. On the AC side i ran a 20 feet thick extension cord to my computer's UPS with a inline AC meter. My UPS accepted it as a safe power source to pass through to my computer managing to power both while also charging the UPS batteries. When first plugged in its load was about 260W then went down too 200W when the UPS batteries were charged. The frequency was exactly 60 most the time. It deviated slightly once by about .03 i think. The voltage would fluctuate a bit between 117 to 122 but those are safe ranges for most things as far as im aware. The fan doesn't come on unless it gets hot or using more than a 100 Watts but I'm not sure if that part's true. I had the fan turn off for a few seconds while pulling 200 Watts through it. The fan is fairly quiet when its on and when it's off there's no way to know it's running other than the dull light in the front. No buzzing coming from it or anything it's plugged into. Aesthetically: it's a metal box which is fine but the end caps to the box are slightly unaligned where the bottom of the end caps have a lip and slightly short on the top. The switch and AC ports are slightly unaligned but you can just shift them back into place yourself since they aren't directly attached to the board. Biggest problem is the USB is so out of place if I plug something into it will have to move the board. The board may just shift into place but visually looks bad and may make the USB ports unusable. Also 16 AWG cable isn't strong enough. The cable was getting hot. I've gotten a 11 AWG cable to use now that should be enough.

## Questions & Answers

**Q: What is the no load power draw in amps?**
A: I just went out and did a 10 minute test, it drew approx. .25 amp no load. Hopefully this helps.

**Q: My alarm sounds continuously and red light stays on. I've tried several batteries and the cigarette outlet. All read over 12v on my multimeter. Why?**
A: Must problems people have with inverters is that their not using proper wire gage rod the power supply secondly when using a cigarette lighter for the power supply it simply is under powered the in line fuse is only 10a or 15a so you only supplying 120dc watts or 180 dc watts and expecting to produce 300ac watts = 2.5 ac amps = 300 dc watts. So get a minimum of #10 wire from the battery to the inverter.

**Q: What is the Warranty?**
A: 18 months.

**Q: Does it have pdf manual?**
A: No

### ⭐⭐⭐⭐ Rated 300 watts, but real world only 120 watts. Power cord severly limits capacity.
*by M***E on February 11, 2022*

While this may be a 300 watt inverter, the issue is that the cigarette power cord significantly limits it's useful power to about 120 watts. Assuming your car is running, and the available voltage is around 14 volts, a 300 watt inverter will pull at least 22 Amps of current (more because it's not 100% efficient). Because this inverter uses a cigarette lighter plug, what they don't tell you is that most cars/trucks only supply about 10 amps to a cigarette lighter plug. So in a typical automotive setup, if you try to draw more than about 120 watts from the inverter, you'll end up blowing the cigarette lighter plug fuse. There are other options to get more power/current from a cigarette plug. For example you could wire your own plug directly to the car battery. But even in this situation, cigarette plugs aren't designed to handle much more than 10 amps. They do not provide very secure connections, and If draw much higher current, you're likely going to melt one or both ends of the plug. In addition, the wire that comes out of the inverter, going to the plug is maybe 16 gauge wire, which is only rated for about 12 amps. Because the length is so short, you "might" be able to push it a little, but if you tried to pull 22 amps through it, to get the full 300 watts, the wire would start to get very warm and possibly melt the insulation. All around an unsafe situation. So in the end, while "technically" you have a 300 watt inverter, you'll never SAFELY be able to hook up a 300 watt load to it without melting either the wire or cigarette lighter plug. Well, why did I give it 4 stars then? Ignoring the 300 watts, it's a very well constructed inverter. I've been using it for about 2 years to power laptops, and power tool battery chargers. All loads less than about 100 watts. The inverter has worked nonstop. It doesn't get hot at all and the fan is very quiet. I've hooked it up to an oscilloscope to check the output waveform, and it is a very nice, clean (symmetrical with no discernible stepping) true sine wave. For the price, it's hard to find something this accurate, even through it's only practical to use it up to about 120 watts.
