600W Power inverter

Purchased for a portable power station build inside a large toolbox. • 5 Lbs. • 8.75” x 5.75” x 3” (+ room for airflow & wiring) • (2) 120VAC Plugs, (1) 5w 2.4 A USB plug Although a little large, it seems to be well built and has a jewel like quality and fineness of fitment. That is offset by shipping it with Copper Coated Aluminum (CCA) cables that have a poor cold weld on the negative (ground) cable alligator clamp. I think this is common, so- if you are experiencing beeping when turning it on, pull back the plastic on the alligator clamps and check the connections! For my needs & usage- it is perfect. Small, extremely well engineered, safe for any electronics- I’m very satisfied. But, at 5Lbs. & almost 9” long- it isn’t exactly a plug & play tool. For emergency use- mine wouldn’t have worked out of the box, as a battery clamp had a bad weld. Also, not being able to plug into a 12v socket (in a car) reduces its usefulness as well. If you were hoping to run a printer in your car & charge your laptop during the day- this will require planning, mounting, wiring, etc… It has (2) 120v AC plugs, so you may need use one for a power strip (multiple small draw items) & a TV/soundbar in the other! There is a 5W 2.1 Amp DC USB plug for passing through some DC power as well. The manual recommends grounding it for safe use and there is a threaded grounding screw mounted on the front panel- like a grown-up inverter! But there is no ability to hardwire it to a power access box? Based on 600W, many will use this in conjunction with a BIG inverter installed in a RV to charge: laptops, tablets, cell phones, camera, drone & tool batteries & perhaps run TV’s & soundbars without running the battery eating 2K or 3K watt monster in the basement. Mine idles at 3W (0.24A or 0.25A) and is 90%+ efficient under load. It’ll work great if the wires are sized properly based on the distance from the battery bank. It’s nice to know that if I leave it on by mistake, it’ll only draw 6AH in a day. Using ring terminals (like the inverter side) I hooked up to a 50AH LiFePO4/LFP battery, it ran fine, however, since I had very short runs from the battery to the terminals and I doubled the wire runs for both Positive & Negative to not waste the CCA and ensure enough electricity flow. It’s a heavy little brick of an inverter (portability is in question, as the battery weighs 15 Lbs. too!) so, for safety, I mounted it on a 3/8” sized sheet of plywood to reinforce the bottom of the toolbox! ‘Portable’ when complete is going to be in the eye of the beholder. 35+ Lbs. is too much for my 5’ 4” 110 Lb. wife- I will be the beholder. Conversely, if you want a good Pure Sine Wave inverter to run/charge smaller AC electronics: TVs, soundbars, printers, wifi, routers, laptops, tablets & cellphones from a battery without your 2k or 3k inverter (heavy idle draw, under-utilized)- this is a great solution! Over gauge the wiring to the battery using at least 50 Amps as your draw- it will run better, cooler & last for many years! You need to be able to continuously discharge 50 Amps to run this at full power (600 Watts), so make sure that your battery can handle that much load-for the length of time needed- if you plan on running multiple items. Heavy draw on small AGM’s & lead acid batteries will cause significant voltage sag and damage both the battery and inverter if it is drawn down too far for too long. The alarm beep starts at 9.8v & cuts out at 9.5v which can happen quick with a tired battery or one that is not fully charged. I like how well designed and engineered it is, but- if I was plugging in a printer in my car- this is overkill. You can get smaller (lower wattage 500W) pure sine wave inverters that can & will plug into your cigarette lighter (12v access or power port) for half the price. All are much less expensive than this one. But, a new Apple laptop or tablet is pretty expensive, a lot more than the price difference of a very good inverter. So, consider your needs and how you intend to use it.

Here is my experience to share. Hope it helps for anyone to consider to buy an inverter. I did a small home project to use a small solar panel as a power backup when there is a power outage and/or use solar power for my electronics a few years ago that needs a good inverter. After many hours of research on Internet, I bought the first Giandel 600W Pure Sine Wave in early 2019 (picture in the right), it was perfect. There is no weird hiss sound when using for my computers and TVs. It is still great as of today in use almost every day because I have an automatic switch that turn it on for around 10 hours a day. When I decided to add a backup battery, I just bought another one of the same branch from Giandel (the picture in the leftmost) last month (Apr 2023). Both of old and new ones work perfect. I will definitely buy again if I need in the future. Living in California, occasionally, there is not a surprise for P&G to shutdown the power without notice due to million reasons such as wild fire risks, etc. Owning a great inverter have saved my days many times. Another great thing is that Giandel has a wonderful service team also. The picture in the middle is another Giandel inverter, 2K, that I received as a replace for the 2K inverter that I bought in late 2019. The 2k inverter was just a backup and hardly put in use. When I reconnected it, it got an issue for some reason that might be too long in storage or some insect got inside or somehow I might not connect it properly, it went bad. I just tried to contact Giandel to check if there was a simple way to fix it. Because it was out of warrant period, I did not expect a replacement. However to my surprise, Elsa from Giandel contacted me and offered me the replacement.

I use this with my 100Ah LiFePo battery to power small appliances--lamp, mini-heater, and white noise machine-- when I go camping. Plus handy during a power outage. I was impressed with how quiet it is. No weird smell. And it didn't warm up much while running a blender and Christmas lights, pulling 420 watts for a good stretch. I like the easy screw on caps for attaching to the "+" and "-" battery terminals. Customer service: Excellent. They respond to my many questions and concerns. That fills me with hope in case something goes wrong during the 18 month warranty period. I love responsiveness. Prevent Sparks: Anytime you connect a battery to an inverter a pop/spark happens as the capacitor quickly chargers. Avoid by bridging negative terminal with a resistor for 5-10 seconds, before connecting as normal. Slows the current = No scary spark! 30 ohm, 25 watt ceramic resistor.

Pure sign wave. Worked flawless way. Much better than my old modified sign wave one.

I wish I could give 5 stars all around, close, but cannot. 5 stars for Customer Support: First of all let me tell you they have real live customer support! Here in the US, in Texas. One of my units failed, and they took VERY good care of me. Responsive. And replaced the unit, with postage paid shipping. Great service! 5 stars for Construction: The physical construction of this Giandel unit is very good. The aluminium case is treated so not to oxidize. And mechanically put together well. Internally the Giandel uses two conductors from the battery terminals to their circuit board. While model XYZ (also here on Amazon) only uses 1 conductor in their 800W unit - and that is not good enough in my opinion. Both units use the same battery manual screw down terminals - which I am not a fan of. 4 stars for the actual 118VAC output quality: While this may or may not be an issue for you, it should be mentioned. I compared the Giandel sine output to a comparable model (Brand XYZ INVT 800W). All in all the brand XYZ unit is not nearly as well built, and the case feels like a first generation unit. HOWEVER the interesting thing is the quality of the sine wave output, from a pure sine point of view, is better in the Brand XYZ unit. I posted some pics. Now, consider this may not affect you, or it may. I think it's application specific. But I mention it because it really did catch my eye as a noisy sine wave as compared to the XYZ brand.

In my opinion this is one of the best choices for both price and functionality for a 12v to 110v inverter.

I took the Giandel 600W camping expecting to use it for powering mattress air pumps and charging phones and computer pads. Because of time restraints I did not check it out before I went camping At camp, I hooked this unit to an auxiliary battery and was not able to generate any AC voltage with the Giandel 600W. I found the red battery wire and clamp that connects to the battery was open, photo 1. Cold (very cold) solder joint and a nonexistent mechanical connection. If I had a soldering iron I could have temporarily repaired this defective connection (oh, I could not have powered the soldering iron without AC power). It is obvious that this cable was not checked before shipment, poor quality control. Also, the other end of the battery connecting cables were poorly crimped, wires frayed and crimped without any effective strain relief, photo 2. Note a small length of 8AWG (4.064 mm) is shown for comparison, the provided wire is smaller, needs to be larger wire for efficient power transfer. At first I thought a fuse had blown in the Giandel 600W, but I was unable to remove the fuse cover(s) you would need a small plyers (I normally do not take small plyers or any plyers camping) I did not/could not remove the fuse covers during the camping trip. So back home, with further investigation, I got the fuse covers off and found 30 Amp fuses (I normally do not take 30 Amp fuses camping). In addition, these fuses are wired in parallel, photos 3 and 4. As an EE, I am asking myself, ”Why would a designer wire 2 fuses in parallel??” Makes me wonder about the rest of the design. Also the bolts and nuts used to mount the fuse holders do not use thread lock or a double nut, these nuts will potentially loosen. (2 of them were lose, as delivered) and fall into the Giandel 600W. Not a good mounting method. Overall, disappointing implementation for higher priced unit. Up Date: Giandel promptly replaced my unit, that had been damaged in shipping. Replacement unit works very well.

Popped this out of the box and into my 100 Amp + 100w DIY solar generator. Worked like magic. Likes: solid feel, good construction, ground connector, remote switch, fuse, fan, four point screws + vibration cushions and reliable. Workaround- Not so like: copper coated aluminum cables (2), connectors too close together. Used own 4 AWD copper cables so not a show stopper. I didn’t have a good battery cable cutter to make my own heavy cables so, arranging the inverter with my inflexible cables, other devices into a tight box was little hassle. Used flexible cable, bought heavy duty crimper and lugs-problem solved. I could have zip tied it to the lid, didn’t want to. The inverter handled all my power-tool recharges and low wattage tests. Lifepo4 battery discharge test was spotless. The inverter shut-off before BMS low voltage shutdown engaged. Similar results with equivalent DIY lead acid deep (no BMS) cycle solar generator. Cables cool to the touch.

Description States 600 watts running 1200 w surge. Would not even handle a 790 Watt surge. Tested it on a 20 amp hour battery, a 100 amp hour battery and a 200 amp hour battery. All failed with a 790 watt half second surge.

Love this! Especially the remote! I use it to plug in my outdoor lights. It works very well.

Good working inverter for the price

This inverter has died less than 1 year after purchase. Was lightly used when purchased and died within minutes of using it at start of this camping season.

Won't turn on unless the USB is unplugged for some reason. Otherwise seems to work fine
