The Bluetti Apex 300 power station and an accompanying B300K battery are huge and hefty. The two units together weigh over 100 pounds, far more than the little DC power supply I sometimes travel with to run my truck’s fridge. But this Bluetti setup can do much more than run a few camping accessories. It can provide shore power to a motor home, charge an EV, or even be the central nervous system for your true off-grid electricity setup.
Bluetti has a deep range of portable power solutions, and Apex 300 is the latest in the lineup. You can grab an Apex 300 at a deep discount right now, especially if you bundle it with ancillary accessories (like solar panels or car chargers, which you’ll want anyway). For example, you can grab an Apex 300 on its own for $1,199, or one with two 200W portable solar panels and a charging cable for $1,799. Or pair an Apex 300 and big B300K battery for $1,999. Check out all the combo options available now on IndieGoGo. We got our hands on an Apex 300 and B300K battery for some testing, and I have to admit they’re pretty impressive.
The Apex 300 may be overkill for day-trippers or even weekend overlanders. But if you’re planning to do multi-day boondocking, want to get serious about setting up a backcountry operating base, or need a home power backup setup that’s much quieter than a generator, check this thing out.
Power and Capabilities
The Apex 300 has 2,764.8Wh of storage capacity and a 3,840W output. It can be switched between 120V and 240V depending on what you’re trying to power—120V of course, applies to most standard plug-in items, 240V runs heavy-duty appliances. And if you need even more juice, you can run up to three of these in parallel for triple the total output.
To add more runtime for your electronics, you can increase the energy storage by slotting a B300K battery below it (as seen in our pictures here) and linking it in with the provided heavy-duty power cable. With multiple Apex 300 units, as many as 18 B300K batteries can be looped into such a system, storing a mind-boggling 58,000Wh of power. That could theoretically power an entire house for a week.
The Apex 300 also supports up to 50A/12,000W bypass capability, is a true 0ms UPS, and has an ultra-low 20W AC idle drain.
Practically speaking, that means the electrical load can be routed without tripping or overheating the bypass switch. That’s important because critical high-voltage items like your HVAC system, fridge, well pump, or similar stuff can keep running when the inverter is bypassed.
An Apex 300 and extra batteries can be wired directly into your home’s electrical system, coming on instantaneously in the event of a power outage (0ms UPS refers to Uninterruptible Power Supply, with 0 milliseconds of transition time from main power). There’s even a weather-alert function that can trigger automatic full-charging of the batteries when a storm is in the forecast. This is called Extreme Weather Alert Mode and is part of Bluetti’s app, which we’ll talk about in a few paragraphs.
The low idle drain spec (20 watts as about as much as a kid’s LED nightlight) means the unit won’t guzzle power when it’s all charged up and running but not in use.
There are six standard AC outlets for plugging in regular household electronics, plus NEMA TT-30R and NEMA 14-50R outputs that could be used to do really heavy electrical work like electric car charging or plugging into a parked RV. You’re not likely to need both of those functions at once, but if your power goes down for a couple of days and your daily driver’s an EV, a Bluetti Apex 300 in your garage could get you going again before the power comes back. Especially if you have an extra B300K battery or two storing juice. Or, if you’re out adventuring in an RV, and want to spend a little time camped out somewhere that doesn’t have electricity, you could load the Apex 300 into the rig and use it for prolonged-stay power just like you’d use those big plugs at a designated campground.
In such a scenario, or in any off-grid setup, you can hook the Apex 300 up to solar photovoltaic arrays to keep them topped up. Or, simply plug it into an AC outlet at home and wait for it to recharge when you’re back from your adventure.
Besides adding more B300K batteries to your system, you can also expand the Apex 300’s usefulness with an accessory called the Hub D1. This is a versatile DC power hub that can output 700W, and has USB-C, USB-A, DC5521, traditional 12-volt cig-lighter plug, and an Anderson port (for more efficient DC power transfers).
Recharging the Apex 300
You can power up the Apex 300 from a home outlet with a standard AC plug, but if you really want to stay off-grid, you can feed it with solar power via photovoltaic arrays.
Another accessory you might want is Bluetti’s Charger 1, which lets you hardwire either a B300K battery or an Apex 300 directly to a vehicle’s electrical system, delivering up to 560W of fast charging and essentially letting the car’s alternator keep the power supply topped up.
Build Quality
Batteries are heavy by nature, so I wasn’t surprised that units as high-capacity as the Apex 300 and B300K had a lot of mass to them. On my home scale, the Apex 300 came in at 83.8 pounds, and the B300K was 63.3.
When you’re dealing with that much inherent weight, you really don’t want things like housings, handles, and buttons to be dinky. Luckily, Bluetti’s units are beautifully built with huge and convenient carry handles, tough-feeling external body panels, and buttons and switches that toggle with satisfyingly decisive clicks.
The large battery storage expansion cables that link the Apex 300 to a B300K battery are similarly stout, giving the paired units a really clean look when connected. They stack perfectly and feel very secure in a tower configuration, too.
All the little covers on the various outlets and inputs have a high-quality rubberized texture to them, and the main display screen is very crisp and easy to read.
User Interface
The Apex 300 has a clean digital dashboard display front and center, reporting all essential information like power level, output level, and other conditional updates. It also reports how much run time you have left at your current level of draw. It looks great and is easy to read in bright or low ambient light.
The buttons and switches are similarly well-executed; everything has a good click to it, and there are clear green LEDs to show you when various functions are activated.
If you want more in-depth info from your power station, check on its status from anywhere, or set it to optimize its charging schedule when storms are in the forecast, you can download Bluetti’s iOS or Android app. I was able to get the iPhone app onto my phone and pair it with the Apex 300 in about 60 seconds. From there, you can monitor absolutely everything about the unit, see how much power it’s putting out, how much is left, update firmware, and execute pretty much any other function from anywhere you have an internet connection (besides physically plugging things in, of course).
How To Get One
