EGO POWER+ Portable Inverter, 400W, Power Inverter Generator, Quiet. Battery and Charger Not Included - PAD5000

Something the big 2000 watt Nexus needs is the ability to charge the batteries while you're using the inverter. This PAD5000 can be charged through the USB-C port while the inverter is powered on! They really need to advertise this because it's a very desirable feature. This way I can power a car fridge while it's being charged by the 12V power outlet (through a 12V to USB-C PD adapter) so that when I turn the car off, the fridge can run off the battery.Other things to note. The LED light has two power levels. It still functions if the inverter has overloaded, and so do the two USB ports and USB-C charging. It draws 48W from my 45W charger and 86W from my 87W charger, so that is good that it can charge at the higher USB PD rates.It has a built-in multi-speed fan that gets a little loud at full output but I'm glad it's there to keep it cool. I'm charging it at 86W, and the fan is running quietly but audible. It doesn't have any rubber feet, so it's going to get scratched up.Another huge improvement over the smaller Nexus is that this outputs a pure sine wave. You never want to use a modified sine wave with pretty much anything these days.I'm also glad it's so much smaller than the monstrosity the larger Nexus is. There is absolutely no reason for it to be that big. I have a 48V pure sine inverter that's the size of a small car amplifier, so I'm sure they can make it smaller.A strange behavior that I noticed is that if you overload it, you can't reset it until you unplug the USB-C charger from the USB-C port. Holding down the power button doesn't do anything until that's unplugged. I would have expected to be able to reset it by simply holding down the power button for a second.Wish list: I wish there was a way to parallel multiple units together for increased runtime and/or capacity. I know I can easily wire more batteries in parallel though if I want to because I did that on my 2000W Nexus so that I could power my window AC all night for camping. I used my eBike's 52V batteries (because Ego batteries are 52V batteries - 14 cells in series). The other reviewer is right in saying that having a power button for the inverter would be nice because sometimes you only need USB power. Shutting off the inverter could save a few watts, though in practice this isn't really significant unless you need to power a low-power device for days at a time.It would be cool if you could use it like a computer UPS, which you can but the problem is that the battery would always be fully charged, and lithium ion batteries never like to be stored fully charged. If you don't already know, the best way to store lithium batteries is at around 40%. If you store them fully charged, you'll quickly find that they won't last longer than a few years, even with their self-discharging feature. It's best to not leave them fully charged for any significant amount of time to reduce permanent degradation of the cells.And speaking of that, it would be cool if you could tell it to stop charging the battery at a certain charge level or voltage, for example 40% for storage or 80% for best life or any percent I choose. Imagine not having to replace a UPS battery for 10-20 years. And this feature should be added to all Ego chargers so that I don't have to manually discharge all my Ego batteries. It's such a waste of time.And speaking of UPSs, it would be nice to have an AC input jack on the unit so that it can be plugged directly into the wall for charging or pass-through charging.Anyhow, I really like it, and I'm sure it'll sell like hotcakes. Good job Ego!

if you have EGO batteries this is a must have for emergencies. Put those batteries to use. I tried a 10AH on my standup full size freezer and it worked like a charm. Ran without issue for several hours, at least 5 before I fell alseep so don't know actual run time. Tried it on a bunch of emergency type of items like fans, lamps, TV, all worked without issue. It even has PD USB C to charge pu my laptop and USB for my iphone and ipad. This will come in super handy the next time there's a power outage. Worked with 2.5AH, 5AH, 10AH batteries, what is nice is that the batter meter remains on the whole time it is in use so you can easily check on the status. I have a table top ice maker and having ice during a power outage is awesome, but it will suck your batteries down fast. Would be cool if they could add it to the ego connect app so that you can monitor run time. Its only 400W so don't even try running a space heater, coffee machine, toaster or microwave oven, only small appliance with light loads should be used. For the price its a terrific accessory for EGO batteries that you would not normally use. Don't need to spend the big bucks for the ego fan when you can plug any fan into this guy. The compact size is perfect, I was looing at the other 4bay inverter but its so big, this little guy can be stored just about anywhere.A couple of things that seems odd and I don't like is that you should use it upside down with the batter on top for best cooling but then this puts the light on the ground and useless. The other is that the handle seems to get in the way, unless you fold it down it blocks the outlets and button. For future versions It would be cool if you could piggyback it with another one so that you would run a mini microwave.

Excellent product use to run heating pad when traveling by car

Got one for general emergencies but wanted to test how it would power my office desk setup: M2 Max Mac Studio, 2X Dell 27" 4K monitors, external LaCie HD (backups), small Pebble speakers, and also charging a M1 MacBook Air. Opened up a bunch of apps (Photoshop, After Effects, Safari, and played live video in Chrome, lots of web tabs opened in both browsers). Total power draw as measured was about 80-100 watts continuous. Used an Ego 5.0 WH 56V battery from full charge. I got to 145 minutes before it dropped to 20% charge, so that's about 3 hours estimated for the whole battery. That implies some loss from the inversion process, but still a decent amount of time. Fan kicks on occasionally and you can definitely hear it, but inverter and the attached battery remained totally cool, I could not detect any heat at all. Power delivery was perfectly smooth, no glitches or anything.So being able to run my home office for 3 hours on a single battery if needed is pretty great (7.5 AH battery should be 4-5 hours). I could probably get even more by dropping down to 1 monitor, killing apps I'm not using, etc. Plus can switch to another battery if available -- there's only 1 terminal so you'd have to power down for the swap obviously. The built in light (which has high/low/off/flashing options) is nice to have. Only thing that might be nice are: built-in ammeter to measure power draw with a small display, and estimated remaining time, and rubber feet so it slides around less.All in all a great compact box to have for...whatever...especially if you already have Ego batteries for other things. Good for emergency use and if you're going to the beach/camping/BBQ in the park or whatever. Just bear in mind it only supports 400W so don't count on running large appliances with it.
