Anker SOLIX C300 DC Portable Power Station, 288Wh, 300W, Outdoor Camping

I have to say that so far I am really loving this Anker battery bank device. It's small enough to be fairly portable, but big enough to hold quite a bit of power for almost any USB charging needs you may have. It was also on sale for a very decent price. I don't have the max power USB charging input for the device but even dual charging from one 45 Watt and one 30 Watt ac power source it only took about 3 hours to fully charge. I have so far used it to pretty much fully charge my Pixel 9Pro phone aprox 7 times, and a large capacity LiFePO4 flashlight about 3 times so far and it still has about 25% charging power left. The one and only problem I had with the unit was the auto sleep mode. The first time it happened it made me think the unit was broken and I was kind of freaking out until I read what had probably happened. According to Anker bringing up the Helix display screen for the unit will take it out of sleep mode but this is incorrect as it could not even connect to the unit until I brought it out of the sleep mode manually by long pressing the power button. Since then I have decided to simply turn off the sleep mode as there is a function for this in the Anker Helix phone app which suits me just fine. :) Also one other thing to note is the unit is SLIGHTLY heavy. Not suprising considering it's holding 90k mAHours of power. Not excessively so and it comes with its own handheld carry strap, but for any long journeys on foot with it I would definitely recommend getting the shoulder strap, putting it into a backpack, or getting one of the 3rd party accessory/protective carrying case units for it.

This power bank works super good! It charged my phone and iPad very fast and still had a lot of charge left! It was smaller than I expected but this thing is still has a lot of power! It’s pretty light weight and easy to move around. Very easy to use just turn it on and plug in your devices and it starts charging. There is an app to download when you can track the wattage going in and out of the device which is pretty cool. Overall though I would definitely recommend this product it is really worth the price! 🤩

There are so many that just purchase without reading - Anker does not hide the fact that it does not come with 'accessories' - I prefer this, helps to keep the cost down (hopefully) reduces waste, and I already have so many of all the cables I need for this for all manners of charging/discharging. Sure, you might need to spend some more money to buy the necessary cables - say $50 for cables and a charger. Well, if Anker includes it for you, I guarantee the price would be more than the $50 over what you paid. Buy as needed. The Li-ion-32 marking on the bottom is a Japanese Recycling indicator. LiFePo4 is still part of the Li-Ion family. 3 = Iron, 2 = phosphore. Anker even has a Solix Support page indicating as such. The cells are LiFePo4 as marketed. Seems this was enough of an issue that Anker redesigned the label as mine states LiFePo4 and no mention of Li-Ion-32. I have not tested the capacity yet, just the initial charge. I received the battery at 30% charge according to the screen, and it consumed roughly 118Wh to charge, so I'll be sure to update this review as time goes on as I will run multiple battery tests on the unit. There will be a loss due to voltage conversion from the 19.2V cells down to 12V DC, and I will account for this. The build quality is excellent, just about as premium as you could get with plastic. The heft is of course due to the cells, but it does feel solid yet lightweight enough to carry. The buttons are very tactile, and the connectors do not feel cheap. The carry strap is a nice quality and I have no complaints there either. The light is very bright, and very white (cool white, I do prefer a warm light) and I like how I can have different light patterns from it. I do wish the 12v socket cover had a tether, I know I'm going to lose it, but it's great that the socket has a separate on/off button. The Bluetooth/wifi feature seems nice. I haven't and won't use the wifi aspect, but Bluetooth updated the unit just fine and controlled the features without problem from my iOS device. I do wish the power station had some security for the Bluetooth aspect to prevent others' from connecting if it happens to be on. Having high-power USB-C out is a big win for me as my laptop can consume it all and then some. A feature I'm glad to see is supported like a standard Solar Charge Controller, DC power-in (solar or DC power-in) and power out to my usb-c laptop, starlink mini, and 12v cooler, all working simultaneously, like how a UPS would work. The power drawn with all 3 devices running was greater than input capacity (100w in) so the battery did continue to drain, just much slower. When I reduced the load the battery did charge with the remaining available power that the starlink and cooler did not consume; fluctuating between 25w and 90w, meaning avaible power to charge the solix was between 75w and 10w. I will state that the marketing of 90,000mAh is so misleading and the standard should be just simply providing a Wh rating - if you consider each cell at 3.2v in this power station, then sure, 90,000mAh is feasible; however, the configuration of the battery cells makes this closer to 15,000mAh (as labeled). Given the rating is 19.2v, it's certainly at least 6S (6 cells in series), which means the capacity (mAh listed) does not increase with cells in series. Without taking it apart yet, my guess is 6S6P 3.2v LiFePo4 rated at 2500mAh cells. I don't plan to disassemble this for a while as I do not want to have any pushback if I need to make a warranty claim. With time I will update the post with performance details and disassembly if/when that happens. I paid $150 in Aug '25, and for $150, it's a great value with the features it has. I do recommend this for anyone looking for a lot of portable power for larger devices, compromising portability and capacity. It's a good balance for my needs.

Finally got around to unboxing my unit. I bought this unit with the intention of charging / staying powered through long weekends away from the grid, camping trips and similar. I’ve got a family of 5 that’s filled to the gills with tech. This device keeps up - effortlessly. Firstly, it’s lighter than I anticipated. I carried it and barely noticed it’s there. Think MacBook Pro. Secondly, it recharges super fast. I use a third party 100w usb c charger and it’s usually 0-100 in a couple hours. Third, the display is loaded with info yet very intuitive. The app is also quite feature packed. I can control the thing remotely and monitor its status easily. Fourth, there’s a nice light at the top. Although I’ve never really used this, it’s nice to have. It’s not super bright but it will keep you from bumping into things in the dark. Now, let’s talk power and battery. All 5 of us have got power hungry phones. Drones. Cameras. Tablets. We’ve recharged everything, at the same time, and we got everything to 100% (from 0) and had well over 70% to spare. We inflated mattresses with the car socket, charged up a BT speaker with the USB A and even ran a mini fan using a 12v inverter. No problems at all. The usb c ports are also very powerful. They charged Lenovo and apple laptops without breaking a sweat at max charging rates. It does get a bit warm but it’s not uncomfortable. Just a couple of degrees. This little unit is 10/10 value - so much so I’m looking into a second one for light home backup.

This is a pretty good item. I have used it quite a bit to charge a variety of electronics or power my Starlink. I like the handle. I can charge it via a normal plug in outlet or with the plug in the back of my Toyota. I think the minimum brightness of the lantern is too bright, and there should be a lower setting. It has powered my devices well so far, but I will be ordering the Anker c1000 so that I can also power my electric cooler.

This thing is a beast. I am currently off grid and it will charge my phone up to 10 times on one charge. The battery life is good. The item is pretty heavy so it's a bit to hike with. It does recommend charging with a 140 watt charger and i agree with that so plan on buying one of those. The top pops up with a light that has three settings so that nice. Has several outputs for different devices and cords. All in all a great purchase for my off grid summer.

Figured I'd start out my review with some Warnings / Notes for new users. -------------------------------------------------------------------------------------- 1. When unpacking this thing, it will NOT turn on unless you charge it first from one of the two bottom right USB C ports. 2. When this thing goes to sleep, pressing the power button will not wake it up - have to press and hold for a few seconds, then it wakes up. This is exactly what I was looking for - didn't need AC but I needed something that could do 100w+ with USB C to power my laptops and various computing devices. I already have an Anker C1000 so this is going to help offload power hungry devices. Had it connected to WiFi for most of the first day I had it - was doing a test to see how much it would drain - stayed 100% (wasn't expecting this). My 16' MBP sees this thing as a 140w power source (using the Apple MagSafe cable) - (via CoconutBattery). I am constantly surprised at the capacity of this thing, I keep expecting the charge to drop due to its small size - 288Wh. This is going to replace my aging and heavily used Anker Powerhouse 521. It is almost half the size and noticeably lighter - and for me, the most important thing, it outputs USB C 140w via 2 ports. I used my Macbook's 140w charger with an Anker 240w Bio cable to power the device - it pulled about 136w constantly while also pulling 100w from my Anker C1000's USB C port. So I was getting about 236-238w charging. Now I need to buy another 140w charger! Keep in mind this does not have an "UPS" mode like the C1000 or the non-DC version of the C300. For me this is exactly what I wanted (something that could provide 100w+ USB C power while being mobile). Going to be offloading usage from my C1000 at night and also will be taking this on a long road trip to power family's laptops/tablets/phones - then charging it at the hotel at night. Despite it reaching 96F+ (according to app) while charging, I heard no fans. As I use this to power my devices I'll update the review on fan noise, but as of this writing, I haven't heard any fan noise yet (I have nowhere near even come to half the unit's capacity). Will update this review with issues/notes as I use this daily. Those of you who know, I reviewed the C1000 and use it to power my entire office during peak hours (4pm - 9am) (been doing this for quite some time now). I was using my small Anker 737 power banks to power my laptop and other devices to help offload power. Now this C300 will be taking over those jobs.

I camp about once a month and I'm a full-time student who studies in a lot of places without reliable outlets. I needed one device that could handle both without making me choose. This is it. The weight is the first thing. Most power stations with real laptop capacity weigh 25 pounds or more. This one is 6.17 pounds. It fits in my hiking pack alongside camping gear and in my campus bag alongside a 15-inch laptop. That combination of actual capacity and actual portability is rarer than it should be. The battery is 288Wh — Anker also advertises it as 90,000mAh, but that number is calculated at the individual cell level and doesn't translate cleanly to real-world use. Stick with the 288Wh figure when comparison shopping. In practice that's four full laptop charges, 15 or so phone charges, and enough left over to run LED camp lights through the night. I've never come back from a two-night trip with it dead. For studying, the two 140W USB-C ports are the standout feature. I can fast-charge my MacBook and run a portable monitor simultaneously without either one throttling. Most power banks top out at 100W on a single port. The 15W USB-C handles my watch, two 12W USB-A ports cover everything else. Seven ports, rarely any choosing between devices. For camping, I paired it with a 100W solar panel. Real-world input on a clear day runs 50–75 watts — not the rated maximum, which requires perfect lab conditions. Budget 4 to 6 hours for a realistic full solar charge rather than the 2.5 hours advertised, and you won't be caught off guard. The popup 360° lantern is the camping feature I didn't expect to love. It draws 3 watts at full brightness, meaning a full charge runs it for over 80 hours. It throws diffused light in every direction rather than a beam, which is genuinely useful for a tent or a campsite table. I've stopped bringing a separate lantern. On recharging speed: Anker claims 0 to 80% in one hour using two 140W chargers. Running a 140W and a 100W cable simultaneously, I went from 27% to full in about 90 minutes. Honest to the claim. The DC versus AC decision comes down to one question: do you need standard wall outlets? The AC version has them but weighs more, costs more, and has a weaker light with fewer USB ports. If everything you own charges over USB-C or USB-A, the DC version is the smarter buy. If you need to run a fan, a CPAP, or any wall-plug appliance, get the AC version instead. A few real complaints: no wall charger included despite the $199 price tag — budget $30 to $50 extra if you don't already own a high-wattage USB-C charger. The rubber cap on the 12V socket has no tether and will get lost. Bluetooth has no pairing security, so anyone nearby with the Anker app can connect to your unit — fine at a remote campsite, worth knowing at a crowded trailhead or campus library. For a student who camps, this is the one. It does both jobs without compromise and fits in the bags I'm already carrying.

This is a fantastic product and has already impressed me massively. Our first proper test was at a festival, where we used it to charge two phones and two smartwatches over three nights. It started at 88% and finished at just 77%! The number of ports is brilliant, making it incredibly versatile when you’ve got several devices to charge. The battery life is genuinely impressive, and the build quality feels excellent. For the capacity, performance and flexibility it offers, it’s worth every single penny. Truly awesome bit of kit and I’d highly recommend it for festivals, camping, travelling or just having as a reliable backup power source.

Very good power station, it can power my MacBook for more than a day…

Sto usando da alcune settimane l’Anker SOLIX C300 DC PowerBank (288Wh, 90.000mAh) e devo dire che è diventato il mio alleato fisso sia in casa che all’aria aperta. La batteria agli ioni di litio ferro fosfato (LiFePO4), molto affidabile e duratura (oltre 3.000 cicli), garantisce che la centrale sia sempre pronta all’uso, anche dopo mesi in magazzino. Il peso e le dimensioni sono gestibili: circa 6 kg, dimensioni compatte (circa 16x16x24 cm) e una comoda maniglia per trasportarla ovunque senza fatica. Carica e gestione dei dispositivi La ricarica è rapida: con l’alimentatore da parete arriva all’80% in circa 50 minuti e può essere ricaricata anche via solare (pannello opzionale, fino a 100W) o tramite accendisigari in auto. Il display LCD è ben leggibile e mostra subito quanto resta di carica e quanto viene erogato. L’app Anker (via Bluetooth/Wi-Fi) permette di monitorare tutto da remoto, anche se per la gestione base basta premere i tasti sul pannello frontale, che sono ben fatti e immediati. Le porte di uscita sono numerose: 2 USB-A, 4 USB-C (di cui due ad alta potenza, fino a 140W ciascuno), una presa DC da auto da 100W, ideali per caricare contemporaneamente laptop, smartphone, tablet, action cam, router, piccoli ventilatori USB, lampade LED, droni e dispositivi a batteria compatti ma non apparecchi elettrodomestici di potenza elevata (es. stufette, frigoriferi grandi, aspirapolveri, etc.). La potenza di uscita totale è di 300W, con un picco di 600W, sufficiente per alimentare quasi tutti i dispositivi digitali portatili, compresi alcuni mini frigo o piccoli monitor. Utilizzo pratico Camping, gite, day trip, viaggi in camper, ma anche casa: l’ho usata come backup durante una breve indisponibilità di corrente e mi ha tenuto illuminato (grazie alla lampadina LED integrata molto brillante), in contatto (router, telefono), con musica (altoparlante alimentato dal C300) e laptop attivo per 2-3 giorni senza grossi problemi. Con una carica piena puoi ricaricare un laptop moderno 3-4 volte, uno smartphone 15-20 volte o una combo di questi dispositivi per un week-end fuori porta senza pensieri. Non offre uscite AC di tipo “prese di corrente” (tipo presa “schuko”), solo USB e DC, quindi è pensato solo per apparecchi a batteria e dispositivi compatibili con le uscite presenti. La ricarica “pass-through” funziona bene, anche se la potenza massima distribuita tra tutte le porte non deve essere superata, altrimenti il caricabatterie limita la corrente automaticamente per evitare sovraccarichi. Comfort ed esperienza L’operazione è plug & play: basta collegare il caricabatterie, accendere e attaccare i tuoi device. Il livello di rumore è molto basso (circa 25 dB), quindi anche al massimo carico non disturba in una tenda o in casa. Il materiale è solido e ben assemblato, i connettori tenaci. La garanzia di 3-5 anni (a seconda del paese di acquisto) e il supporto Anker sono ulteriori punti di forza. La ricarica solare non è fornita (va acquistato il pannello separato, Anker 100W consigliato per la massima compatibilità), ma funziona bene per chi ama il campeggio off-grid o vuole ottimizzare l’autonomia sostenibile. Aspetti da migliorare - Nessuna presa AC: non puoi collegare dispositivi che necessitano di corrente alternata classica (es. aspirapolveri, frigoriferi di taglia media, etc.). - Peso: non è “leggero” come una normale power bank, ma la portabilità è comunque molto buona rispetto alla capacità. - App: utile soprattutto per il controllo remoto, ma a volte la connessione può essere un po’ traballante (non blocca però il funzionamento manuale). - Pannello solare non incluso: se prevedi di usare spesso la ricarica solare, dovrai acquistarlo a parte. Vantaggi principali - Capienza e potenza: 288Wh, 300W, batteria LiFePO4, carica ultrarapida. - Versatilità: ricarica da rete, pannello solare, auto. - Silenziosità: perfetta per uso notturno. - Portabilità: compatta, maniglia, ideale per viaggi/escursioni/uso domestico. - Qualità e affidabilità: Anker è una garanzia, costruzione robusta, garanzia lunga. - App di controllo: per chi vuole il massimo del monitoraggio. In sintesi Se cerchi una power station affidabile, comoda da trasportare, con massima flessibilità di ricarica e sicurezza energetica per i tuoi dispositivi digitali, l’Anker SOLIX C300 DC è una scelta eccellente. Non sostituisce un gruppo elettrogeno né alimenta grandi elettrodomestici, ma per tutto ciò che è portatile, ti cambia la vita: ti ridà autonomia e sicurezza senza rinunciare alla qualità e alla facilità d’uso. Io la consiglio a chi fa sport outdoor, viaggia spesso o vuole un backup energetico smart e moderno in casa.

Ich nutze die Anker SOLIX C300X DC täglich auf der Arbeit (ich bin Drohnenpilot) und bin sehr zufrieden. Das Gerät läuft zuverlässig, ist sauber verarbeitet und liefert konstant Leistung – so, wie man es von Anker erwartet. Das Preis-Leistungs-Verhältnis ist für mich der größte Pluspunkt: Man bekommt extrem viel Kapazität pro Euro in guter Qualität. Die Powerstation hat mehrere starke Ausgänge, teils bis 140 W pro USB-C – ideal für Laptop, Drohnenakkus & Co. Ein Netzteil liegt nicht bei, aber wer solche Geräte nutzt, hat meist passende Schnellladegeräte schon zu Hause. Praktisch: Man kann sie sogar mit zwei Ladegeräten gleichzeitig laden, was das Aufladen deutlich beschleunigt. Sehr gelungen ist auch die LED-Lampe, die man seitlich ausrichten kann, sodass das Licht genau dort ankommt, wo man es braucht. Ich habe eine zweite an meine Schwiegermutter in der Ukraine verschenkt – bei Stromausfällen ein echter Lebensretter. Klare Empfehlung.
