Perfect gift for my son in law. He loves it and says it works great!

So far so good, just received my unit... fast charging my samsung s23 ultra, my samsung tablet and charging my tablet and laptop... with the l 200w inverter via 12v car cigarette port. The led indicator is at 12.3.. I. Guessing I just have to make sure the led doesn't reach over 20.. since my car fuses are 20

Living in the hills of Southern California, you learn quickly that planning for emergencies isn’t just a hobby—it’s a necessity. Between wildfires, power outages, and the general unpredictability of the grid these days, it’s become second nature for us to build little redundancies into how we live. That’s how we ended up discovering just how useful the RoyPow 300W Car Power Inverter could be. I already have a heavy-duty inverter setup that taps directly into our EV’s charging port and puts out up to 1800 watts, which is more than enough to run major appliances in a pinch. But for the majority of our needs—keeping a laptop running, powering a lamp, charging phones or a small fan—this smaller inverter is surprisingly sufficient, and more importantly, far more convenient. We first really tested this RoyPow inverter during the recent wildfire evacuations. Though we weren’t hit directly, we were displaced long enough that power at home was unreliable. One of the smartest moves we made was using our EV as a backup power source. By plugging this unit into the 12V “cigarette lighter” port (which, let’s be honest, probably deserves a new name in the 2020s), we had a steady stream of modest, clean power to use wherever we needed it. Our big appliances were covered by the larger inverter, but it was the RoyPow that ran the show for the essentials: recharging our phones, powering the internet router when we could get signal, and even keeping a work laptop going for Zoom meetings. The inverter’s compact size makes it feel more like a travel charger than a piece of emergency equipment, but don’t let that fool you. It puts out a stable 300W (with 600W peak) across dual AC outlets, and it also sports multiple USB ports—USB-A, QC3.0, and two USB-C PD ports rated at 30W and 36W respectively. That gives you enough flexibility to charge a surprising variety of devices without needing separate adapters. I normally charge my Galaxy Ultra using a 45W charger at home, so while the USB-C PD ports here aren’t quite as fast, they’re still very serviceable. You won’t get lightning-fast charging speeds, but if you’re using this in a car or during an outage, it’s more than enough to get the job done. In day-to-day use, what really impressed me was how quietly and efficiently it runs. I’ve had other inverters that hum or even vibrate slightly when in use, especially under load. This one stays impressively cool and nearly silent. I used it for a few hours straight one evening while camping just to power some LED lights and top off devices, and it never gave me any trouble. And unlike bulkier or more industrial-looking models, the RoyPow blends in and tucks away neatly when not in use. It doesn’t rattle around in the glove box or center console either, which may sound minor, but anyone who hates road noise knows what I mean. Now, it’s not perfect. While it’s great for small electronics and some light office gear, you’re not going to run a full kitchen or power tools with this thing—and nor should you expect to. If you try to draw too much from it, it’ll cut out, which is honestly a good thing, as it helps prevent damage to both the inverter and your car’s electrical system. And while the USB ports are useful, I still find myself leaning on my standalone fast chargers when I’m near wall power, simply because they deliver more juice for my high-drain devices. But again, this inverter isn’t about peak performance—it’s about consistent, emergency-ready access to power when you’re not near an outlet. At this point, I’ve ended up placing inverters like this in every car we own, just as a matter of preparedness. But the RoyPow has become the dedicated inverter for our EV. It’s small enough to stash without thought, powerful enough to cover 90% of our mobile needs, and versatile enough that we’ve come to rely on it both during emergencies and for day trips, road travel, and camping weekends. When you’ve got kids trying to keep their phones alive or finish a homework assignment in the car, a power inverter like this starts to feel like less of an accessory and more like a necessity. I’m giving this a solid 4 stars, mostly because while it’s not the most powerful inverter I own, it’s hands-down the most useful for everyday, moderate-power needs. The design is practical, the outputs are varied enough to cover most situations, and the peace of mind it gives me is well worth the price. In a world where staying connected and powered-up feels more essential than ever, this little device definitely earns its spot in the car.

I bought this on March 28, 2025, and used it 2 or 3 times to power my laptop. My Lenovo laptop charger draws 135W as stated on the output spec or the charging block. The Inverter is rated for 300W. This charger worked fine for the first couple of uses. On the last use, it would only change for a few seconds, then the laptop showed it was not plugged in. I plugged in a voltmeter, and it showed that the voltage output was only 96V. This is apparently too low to power the charger. This charger had a small fan, USB charging ports, and a nice look. But, it turned out to be very unreliable. DO NOT BUY.
