Anker SOLIX C300 — A Ham Radio Operator's Honest Review After 72 Hours of Real-World UPS Testing ★★★★★ Background: I'm a licensed amateur radio operator (CW, HF) and outdoor cook with two pellet grills. I needed a unit that could do three things: bridge a 15-second Generac whole-house generator cutover for a 21-inch iMac, charge laptops and phones on the go, and power a 12V telescope mount and camera at dark sky sites. Here's what I found after 72+ hours of systematic testing. --- HOW I GOT HERE --- After the Nomad400 failure I researched every portable power station in the 256-300Wh class for dual UPS and portable use. The C300 won out over the EcoFlow River 3 (AC shutoff firmware bugs), the Jackery Explorer 300 V2 (no app support), and the GoldenMate LFP UPS (purpose built but no portable use case). $229.99 on a Amazon was also the best price I found after weeks of research. --- SETUP --- Dead simple. Plug into wall, plug iMac into AC outlet, long press power button, press AC button. That's it. The Anker app connected via Bluetooth instantly and prompted a firmware update (v1.0.5.1) which installed cleanly. Two settings worth configuring immediately in the app: set Device Timeout to Never, and confirm Smart AC Output Mode is off. Output Port Memory Switch should be on — this ensures the AC output re-enables automatically if the unit ever loses power and restarts. --- UPS PERFORMANCE --- This is the main event. In passthrough mode the display shows "--" on input and your load wattage on output, with battery holding at 100%. This is correct and expected behavior — when the battery is full the unit passes wall power straight through without drawing from the battery, so there's nothing to display on the input side. Don't be alarmed by the "--". The switchover test was flawless. With a TextEdit document open and text typed, I pulled the wall plug. The iMac didn't blink. Not a flicker, not a hesitation — completely seamless. The C300 display showed the switch to battery mode. After discharging a bit (to 95%) I plugged back in and everything was exactly as I left it. Anker rates the switchover at under 10ms and based on my testing that's credible. The iMac draws between 34W and 100W depending on processor load, averaging around 55-65W in normal use. After 24 hours of continuous passthrough operation — including overnight unattended — the battery has held at 100% throughout. This is the test the competing unit failed in under 4 hours. The C300 passed without drama. --- REAL NUMBERS --- Here's what the display showed at various points during 24 hours of testing: — Passthrough idle: 0W input, 34-64W output, 100% battery — Charging from 95% back to 100%: 170W input, 56W output — Temperature throughout: 89-98°F (32-37°C), well within normal range — Fan behavior in passthrough: completely silent — Switchover relay click: audible but quiet, reassuring The fan only runs during active charging at higher wattage. In permanent UPS standby mode you will not hear it. This is a significant advantage over traditional UPS units that run their fans continuously. --- APP --- The Anker app is genuinely useful for this application. Real-time monitoring of battery percentage, input wattage, output wattage, and temperature without walking over to the unit. Firmware updates are delivered cleanly with actual change notes. The ability to configure timeout settings and output modes remotely makes it far more capable than competing units that offer LCD and buttons only. Connected via WiFi the monitoring works from anywhere in the house. --- PORTABLE USE --- At 9.1 lbs the C300 is genuinely portable. The 140W USB-C port charges a 15-inch MacBook Air at full speed — roughly 3 full charges from the 288Wh battery. The 12V car socket will power my Celestron AVX telescope mount and 12V astronomy camera directly without burning the AC inverter, which saves capacity and runs cleaner. Starlink Mini (20-30W draw) is well within its capability for extended field sessions. --- HONEST OBSERVATIONS --- The display shows "--" for input in passthrough mode which initially caused concern — it's normal and correct behavior, not a fault. The unit shows "273 days" remaining runtime when plugged into wall power regardless of load. This is clearly a software quirk for displaying effectively unlimited runtime. Amusing but harmless. Third party carrying cases are available on Amazon for $15-25. Anker's own bag is $59 — skip it and get a third party option that does the same job. AC recharging power defaults to 100W in the app. You can increase to 330W for faster top-up after an outage, but 100W is gentler on the battery for permanent UPS duty. --- CONTEXT: PREVIOUS UNIT FAILURE --- For anyone comparing the C300 to the AFERIY Nomad400: the Nomad400 showed excellent UPS switchover, silent fan, and clear display on arrival, but its passthrough charging circuit failed within hours — the unit drained its battery to 3% while plugged into the wall. The C300 has shown none of this behavior after 24 hours of identical testing. The passthrough reliability difference is night and day. --- BOTTOM LINE --- Pure sine wave, LFP battery with 3,000+ cycle life, 10ms UPS switchover, full app control, silent fan in standby, 5-year warranty, and 72 hours of real-world testing with zero issues. At $229.99 on sale it's the best value in its class for anyone needing a reliable desktop UPS that doubles as a capable portable power station. Highly recommended.

This is a neat, compact, and well-designed portable power station that’s easy to use and easy to carry. I really appreciate that it includes three standard 120-volt AC outlets and a common desktop-style power cord for charging from a wall outlet. It also offers multiple USB ports, making it very versatile for everyday use. I tested it in a couple of real-world scenarios. When powering my laptop, the unit dropped from 100% to 64% after two hours, which suggests it could run the laptop for roughly four hours total. When powering my home network equipment, it only dropped from 100% to 80% after two hours, indicating about ten hours of runtime for lighter loads. Recharging is quick, which makes it convenient to use regularly. The built-in handle makes it easy to carry, and the overall build quality is excellent. It feels solid, well-made, and dependable—exactly what you want from a portable power station. I haven’t experienced any issues during long-term use, and it has performed reliably every time. The companion app is straightforward and works well, allowing you to monitor battery level, charging status, and performance. While it may be more than casual users strictly need, it’s genuinely useful and easy to navigate. Overall, I highly recommend this unit for everyday, casual use such as charging phones, tablets, running small lights, or powering other low-draw devices. If you’re looking for a compact, reliable power station from a trusted brand, this one delivers.

I am someone who relies on a product to do the task I need done. I will try any product out, however when I saw Anker made a portable power station, I bought it in an instant. I do not regret that decision at all. I’m even considering buying another one. What I liked about the system is it that it charges the whole thing in about an hour. You have no idea how important having an AC charger is for a portable power station. There are other power stations out there that are charged by a USB-C cord. They will take three times as long to fully charge andand you might need two cords. I don’t have a place to live right now. I also don’t have I don’t have three hours to wait to charge any power station, or electric device in the world. This works for me. The other day it charged from 3% to 100% in less than 57 minutes. I wouldn’t say everybody needs to charge their power station in an hour but if you use it for the next 72 then I think it’s worth it. And that’s about how long I have to charge once every three days give or take. Not everything is perfect in this world like the USB-C method. Yeah it’s fast and convenient but if you’re making a right term and you’re charging something and all of a sudden you have to come to complete stop USB-C cord isn’t going to be very happy. So my issue was one of the ports stopped working because of my own idiotic life. But there’s still two ports left. I have an idea for a resign, but I don’t work for anchor but if I did, I would take out the two AC ports, but leave one to charge And one of course for an outlet and add two more USB ports, but we’ve got to find a way to stop them from ripping out and ruining the port I wish I was technology that’s not even a thing, but you know how gas station pumps have breakaway hoses something like that. What I struggle with is USB-C technology. It’s fast and convenient, but those chords and plugs rip out a lot of times ruining the port and ruining the cable where they get stepped on or water or iced tea gets in there by accident. Regardless, this is a great product and I just thinkthink the technology needs to change, Beyond the product, which is a great price and a lot of power, the customer service support at Anker is one of the best. I’m not being paid anything to write this. I wish I was cause I could make it really sound good but I don’t need to. Anker is probably one of the best if not the best in chargers, cables, power stations, and I’m in need of a Bluetooth speaker now so maybe they’re the best in that department too. When you have an excellent product and a helpful and knowledgeable customer service department, you earn a five star review on Amazon and a customer for the rest of their life.

This is a nice, neat, compact power supply. I appreciate that it has three 120 volt outputs and a standard fitting to charge it from a 120 volt outlet - the same as on a desktop computer. It also has multiple USB ports. I tested it twice. I used it to supply my laptop. After two hours of use, the power station fell from 100 percent charge to 64 percent, indicating that it would be able to power the laptop for about 5 hours. I also used it to supply my home network equipment. After two hours the power station fell from 100 percent to 80 percent, showing that it would power the network for about 10 hours, It recharges quickly. It has a built-in handle and is easy to carry that way. I am very pleased with this purchase.

Really good power bank I can charge my laptop a couple times. Specifically, if I use the USB-c port I can triple the number of recharge for my laptop. The app is pretty easy to use and straightforward. I love the display screen too showing the hours remaining etc. though, you can view from the phone app. The built in light is not that bright but it’s workable. Good purchase, if you’re considering getting the solar that’s the bonus. I didn’t since I just recharged with a generator but I do see how that would be a plus. It’s super quiet and quiet compact. I tab bit heavy but not overbearing. Ps it supports fast charge :) and can be charge by your car

It's great. Don't expect unrealistic power but it will power larger item for a short burst. I bought this to power my 50W travel cooler. It could last for 6–9 hours straight with no issues. I keep it in the back of my SUV, always plugged in on 100W charge mode, so it’s usually full on trips and ready to take over when we stop. Really convenient with a toddler since we can keep food cold anywhere all day long. It's powered the cooler in 110°F + heat inside a car for 7 hours without issue multiple times. Cooler stayed 38°. It’s also handy around the garage for charging tools, and in Florida it’s part of my hurricane kit (paired with a C1000 I can run a fridge for a 12-20 hours, or two small coolers for 2–3 days). Simple, versatile, and reliable. Original review: Seems light enough to travel and small enough to pack (car, campsite, hotel, not hike) compared to 1000 which is 20lbs heavier and 3x bigger. Does what it says, don't expect to power you full size fridge for days, but will power small devices for the weekend. 1000 series powered 150watts for 3 hours and used 35% when I tested my garage fridge. Have not tested this unit that much yet but that would have been the entire battery for the 300 unit. I'll update after I test more.

The Anker SOLIX C300 Portable Power Station has been a great companion for camping trips. It’s compact, easy to carry, and provides plenty of reliable power for charging phones, lights, and small devices while outdoors. The 288Wh LiFePO4 battery feels dependable and holds charge well, even after multiple uses. It’s simple to use with clear ports and fast charging options, and it gives real peace of mind when you’re off the grid. For camping, it’s the perfect balance of portability and power.

Recharges my Dell laptop that has a battery that loses its charge in a couple hours of remote work. This Anker will recharge the laptop while working on the laptop about 2 hours. After another 2 hours, Anker can recharge it again 1 or 2 more times. We don't use the car or solar adapter, just house recharge. One thing to remember- if the lower power button near the AC outlets is left on, even with the laptop power chord disconnected from the laptop, the blue light on a laptop power chord will eventually drain the Anker over hours. So turn off that button, leaving the laptop chord connected is fine - but its hard to see its little led light on the Anker button, so easy to miss. Otherwise … no charge on Anker when needed. A little heavy but the shoulder bag they sell makes it easy.

Al een aantal keer nodig gehad bij stroomonderbreking. Werkt handig. Robuust.

I now have 2 Anker Solix C300 power stations. My second power station did not work out of the box. I did all the trouble shooting before I contacted Anker support via their website. They also confirmed my trouble shooting and agreed for me to return the faulty item and a new replacement was shipped out. Their communication and responses were timely and very helpful. This gave me a lot of confidence with Anker. Very pleased with the product and the support when something went wrong.

Top,je ne m'attendais pas a cette capacité de tenir une charge aussi longue Utilisé,pour un lampadaire a fonctionner (12h) Charge appareil relié au fiche USB pendant des heures,un frigo box 26 L ( fiche 12v) Avec une seule charge complète ( chargé pendant 1/30h ) Des qu'il fera beau, j'installerai les panneaux solaires qui vont avec

cette station est très bien par ses multiples connections in and out, la possibilité de recharger sur le secteur, les panneaux solaires. Une charge suffit pour alimenter tous les appareils pc, smartphones, lampes led, etc. pour toute une soirée en tente, et même deux. Je la recommande

I bought this to power a small music setup for pedals, amp, etc. Works great!! Slick product. Well worth your money$$$$ I wish I had this years ago. LOL
