Best MILIN Portable Power Station: Is the 622Wh Model Alright?

A power outage never waits for a convenient moment, and this is exactly the problem the MILIN portable power station solves. This 622Wh unit promises camping trip reliability and budget friendly backup power, but promises only matter when the users back them up. So we reviewed this MILIN station to get you to fully understand whether the MILIN 622Wh, 600W deserves a place in your van, garage, or camping gear list.

Let’s get right into it.

What Is the MILIN Portable Power Station?

MILIN is a budget focused brand that built its reputation on this exact model since the early 2020s. It is not a household name like Jackery or Anker, and it doesn’t pretend to be. Instead, this portable power station leans on a simple formula: useful capacity in a compact box, priced below premium competitors, and backed by proper safety certifications.

That approach has earned MILIN a loyal, if modest, following among campers, van dwellers, and users who want backup power without a four figure price tag. Is MILIN actually a brand worth trusting, though? Based on feedback, the answer is yes (but with a few caveats.)

The company holds UL, FCC, and UN38.3 certification, and its support team has stepped in more than once to replace faulty display panels or troubleshoot charging problems for its customers. That said, there have been reports of units failing within a year or two. That means MILIN is a solid budget brand rather than a flawless one, so you should plan accordingly.

Will It Actually Run Your Gear?

Users are running their machines through the entire nights and wake up with more than half the battery still available, even with humidity settings turned on. That single use case alone has convinced plenty of tent campers and van lifers that this portable power station earns its keep.

You can run it daily inside a mobile locksmith van to power key cutters and a bench grinder. Furthermore, you can treat it as a weekly work tool, and use it for four to six hours of live street performances while still keeping 60 to 70 percent of the charge in reserve afterward.

You can also run an 800 watt portable speaker off it for hours without a problem, and you can use it for a hunting cabin setup with lighting, phone charging, and a small water pump. Laptops, tablets, fans, and camera batteries all charge without much drama on top of those bigger jobs.

However, one drawback is: the DC port shuts off automatically when it detects no steady power draw, so appliances that cycle on and off, like a portable 12 volt fridge, might lose power unexpectedly. Route a mini fridge through the AC outlet instead to sidestep the issue entirely.

Every CPAP, fridge, or power tool pulls a slightly different load, so guessing is not the smart way to go. Before you assume the MILIN 622Wh covers your exact setup, run your own device list through our portable power station sizing calculator and get a real number instead of an estimate.

Battery Type and Charging Speed

The MILIN 622Wh uses standard lithium ion cells rather than LiFePO4 chemistry. This likely means fewer total charge cycles over its lifespan compared to a similarly priced LiFePO4 rival. Day to day performance still feels the same, though, so this mostly matters for users planning years of heavy use.

On the plus side, charging through the wall outlet and USB-C port together pushes combined input past 100 watts, cutting charge time noticeably compared to using either port alone. A full recharge might take longer in reality, so budget six to seven hours from empty.

Solar recharging works great, although it can also run noticeably slower than wall or car charging at occasions. Treat solar as a helpful backup method rather than your primary charging plan, so you won’t be disappointed.

If long-term battery chemistry matters more to you than saving money, skip ahead to our under-$500 lineup of LiFePO4 picks built to outlast this one instead.

Ports, and Portability

At roughly 15 pounds, the unit sits in that sweet spot where it’s genuinely easy to carry, yet still heavy enough to remind you it holds real capacity. The side handles and flat top design make it simple to slide into a backpack, duffel bag, or the back seat of an SUV.

Here is what you get access to on the unit itself:

• Two 110V pure sine wave AC outlets for sensitive electronics
• One 100W USB-C port that supports both input and output
• Three USB-A ports and two DC ports for smaller devices
• A built in flashlight with an SOS mode for emergencies
• An LCD display showing real time input and output wattage

Together, these ports cover nearly every charging scenario you would realistically need.

Pros and Cons

Pros	Cons
Reliably runs CPAP machines all night with charge to spare	DC port cuts power to intermittent draw devices like mini fridges
Simultaneous AC and USB-C charging pushes past 100W combined	A meaningful share of units develop display or charging faults within 1 to 2 years
Lightweight, backpack friendly build with side handles
Strong value against pricier name brand competitors

Overall, the pattern is neat; when the MILIN portable power station works as intended, which it is doing for the large majority of users, it delivers genuine value.

When something goes wrong, though, it tends to go wrong in a way that is hard to ignore. And that’s exactly why you might see it rated a touch lower compared to its rivals.

How Does It Compare to Jackery, Anker, and Bluetti?

Here’s a quick side by side against the top brands for your cross reference.

Brand and Model	Capacity	Battery Type	Price Bracket	Best For
MILIN 622Wh	622Wh	Lithium ion	Budget	First time users on a tight budget
Jackery Explorer 500	518Wh	Lithium ion	Mid range	Balanced reliability and support
Anker SOLIX C300	288Wh	LiFePO4	Mid range	Long term durability, smaller size
Bluetti AC180	1152Wh	LiFePO4	Premium	Larger households, longer outages

In short, the MILIN 622Wh wins on price and capacity per dollar, while the LiFePO4 competitors win on long term battery health. Which factor matters more depends entirely on how long you plan to keep the unit in rotation.

Who Should Buy the MILIN Portable Power Station?

This model makes sense for the budget conscious campers, van lifers, and specific users who want dependable backup power without spending Jackery or Bluetti money. It particularly suits anyone who mainly needs to charge phones, laptops, fans, lights, or a CPAP machine. First time users not ready to commit extra money toward a LiFePO4 flagship will find this a sensible entry point.

On the other hand, if your plan depends on running a 12 volt fridge continuously off the DC port, a LiFePO4 model from Jackery, Anker, or Bluetti will serve you better long term.

If this 622Wh is more firepower than you normally work with, our review of the ZeroKor’s featherweight 300W solar bundle covers a lighter, cheaper option built for exactly that smaller job.

Final Verdict

The MILIN 622Wh remains a smart purchase (or even an upgrade, essentially) for anyone who wants genuine backup power on a modest budget. It comfortably keeps CPAP machines, laptops, phones, and small appliances running through a camping trip or an outage. The simultaneous charging feature is a legitimate convenience that plenty of budget rivals skip entirely.

Just plan around the DC port’s auto shutoff behavior, and understand you are trading some long term battery longevity for a lower price tag.
