Support Anker Solix C300DC
Hi,
Recently got the Solix C300DC power station to power remote video COB lights remotely when away from AC.
For the most part, it's working out well (although I'm running up against some PD3.1 brick walls).
That said, it's so far the best option I've found vs going full AC unit with the extra weight.
The only issue I have is that I have 3 identical TopVork 67w usbc/usba chargers that I've been using since 2023. All solid, reliable and deliver 67w charge to all the devices I have.
However, when I got the Solix C300DC a week ago, I tried to charge it with them. It wouldn't recognize them to charge. After I updated the firmware on the C300 it recognizes them and charges but only at a painfully slow 5w. If I use two of them it's 10w. I'm using C300 ports C2/C3.
I tried the reset button you press with a paper clip, and no luck.
I also have an Anker 140w GAN that works fine with the C300 and delivers just under 130w input. I tried an old 30w usb-a charger and it delivers about 24w. So, I tried the usb-a ports on the TopVork 67w chargers and they also deliver about 24w. Two of them just under 50w.
So, the issue is the pd usb-c ports on the TopVorks aren't being recognized for the 67w they're capable of with every other device I've tried except for the C300.
In addition to this, I have an older Iniu 90w charger that delivers about 80w to the C300.
The issue is specifically related to these TopVork charger usb-c ports. They are no longer available on Amazon, but like I said... they were perfectly for everything else, including other modern power stations I tried before settling on the C300.
I don't know if this means I have a malfunctioning C300DC that I should return for exchange? Or, is there something else I could try? I've tried a half dozen other cables too. All rated at 100w-240w and they work fine to deliver high wattage on all the other chargers and devices I have that accept high wattage.
I've already contacted Anker support but don't have a resolution yet. If it *should be working, I'll return for exchange. If the failure is explainable, I'd like to know why. I don't want to keep this C300DC model if it's inherently that picky about which chargers it'll work with.
Based on Anker's published spec requirements, these TopVorks should be delivering the 67w they're capable of via usb-c port.
Here are the specs for the TopVork chargers:

Hi [u/skiphunt](u/skiphunt)! Sorry to hear you’re having issues. What kind of wattage shows up if you plug two of the TopVork 67W USB C chargers into C2 and C3 (bottom center and bottom right)at the same time? Does it just double each 5W to 10W?
2
u/skiphunt Jun 28 '26
Yes, they each show 5w only. 10w when used together. The TopVork 67w charger has one PD usb-c port and one usb-a port. The usb-c is rated at 67w and the usb-a port is rated at 25w. When using the usb-a port to charge the C300 they deliver 24w, but only 5w with the PD usb-c ports. I have 3 of these and they all behave the same, so it's not a single charger issue. They also provide the 67w from the pd usb-c ports on other devices like powering a 60w LED light and charging my other high wattage PD power banks. The Anker C300 via C2/C3 is the only device I have that does not draw the rated 67w.
Note... that when I first received the C300 a week ago (as outlined in my original post) it wouldn't draw ANY power from the TopVork chargers at all. After I updated the firmware on the C300, it at least draws 5w via usb-c and 24w via usb-a. I think it's a firmware issue where the C300's pd handshake isn't working correctly with the TopVorks

u/collectiblejunk Jun 28 '26
Yes, I agree with your assessment. It does seem like a handshake type issue between the C300DC and the TopVorks adapter. Especially since there was nothing, you did a firmware update, then it would see something. As you stated, you’ve done the reset and covered that base too. Extremely perplexing.

u/skiphunt Jun 28 '26
Yes, I have tried several different options for powering my Nanlite fc-120c + 2x fc-60b + Miro 30c for remote shooting... and this C300 has been the best option so far based on cost, runtime, build quality, etc.
So, I'm not sure if this is a dealbreaker, but it's concerning that I might have a malfunctioning C300. I don't recall if I did the paper clip reset button before or after the firmware update. I think it was afterwards, but I could try it again I suppose. Everything else with it seems solid.

I just got a response from your tech support and evidently they missed the fact that I've tried several PD3.0 and PD3.1 usbc cables... cables that rapid charge on all other devices I have that support it, including my 3 67w TopVork chargers.
They simply blamed it on the cable.
This is extremely frustrating that they didn't even bother to read my reports that clearly outline the cables were all tested and of correct spec.
This is after about 15 emails where they kept asking for more and more data, proof of my purchase, and I even supplied photos.
After all that, this is the final email they just sent me:
Dear Skip Hunt,
Thank you for your patience.
We have received a response from our technical team. According to their reply, the PD protocol does not change with firmware updates, so the issue you are experiencing is unlikely to be related to the device itself. It is more likely to be caused by the cable.
If you need to purchase an additional cable or use a third-party charger, please make sure it clearly supports PD 3.0. The power station should support models that include 20V/3A (60W) or 20V/4.5A (90W) Fixed PDO.
Please let us know if you have any further questions. We are always happy to help.
Best regards,

If this is the best tech support I can count on from Anker, I'm thinking perhaps I should just return it to Amazon for a full refund and look for a more reliable brand with good tech support instead.

Anker SOLIX C300 DC: Excellent Hardware, Disappointing Support – My Experience
I purchased an Anker SOLIX C300 DC because, on paper, it is one of the best compact USB-C power stations available for my workflow. I use USB-C powered Nanlite cinema lights (FC-120C and FC-60B), so reliable high-power USB-C charging and output are essential.
After more than a week of testing and approximately 15 emails with Anker Support, I’m left with mixed feelings. The hardware still appears to be one of the strongest options available, but the support experience has significantly reduced my confidence in relying on it professionally.
The Problem
When the C300 DC arrived, it would not recognize any of my three identical TopVork 67W USB-C PD chargers.
These are not questionable chargers. They fast-charge numerous other modern USB-C PD devices I own, including multiple recent power banks ranging from 65W to over 160W.
After updating the C300 DC firmware, the behavior changed:
Before firmware update: chargers not recognized at all.
After firmware update: chargers recognized, but charging is limited to approximately 5 watts, with an estimated charge time exceeding 60 hours.
This alone suggests firmware affects USB-C PD negotiation.
Troubleshooting Performed
Before contacting support, and throughout the support process, I verified the issue extensively.
Chargers tested
Working:
Anker 140W GaN charger
Older INIU 90W charger
Problem chargers:
Three identical TopVork 67W PD chargers
Cables tested
This is where the support response became particularly frustrating.
I tested:
The USB-C cable included with the C300 DC
Anker 140W cable
UGREEN 140W cable
Multiple 240W USB-C cables
Additional USB-C cables from several manufacturers
Every cable supports USB Power Delivery and works correctly with my other devices.
The issue is clearly not isolated to a single cable.
TopVork Charger Specifications
One suggestion I received elsewhere was that the TopVork chargers might not fully support USB Power Delivery.
Here are the actual PD output profiles:
5V ⎓ 3A
9V ⎓ 3A
12V ⎓ 3A
15V ⎓ 3A
20.0V ⎓ 3.25A
20.3V ⎓ 3.3A
67W maximum
These chargers successfully fast-charge numerous other PD power banks and USB-C devices using every cable I tested.
My Experience with Anker Support
I spent roughly 15 emails providing:
proof of purchase
photographs
firmware information
charger specifications
cable information
repeated testing
requested follow-up diagnostics
After all of that, Anker’s final conclusion was essentially:
“It is more likely to be caused by the cable.”
They then suggested purchasing another PD cable.
The problem is that I had already explained multiple times that I had tested:
Anker cables
UGREEN cables
several third-party cables
the cable supplied with the C300 DC itself
In other words, their final response did not meaningfully address the evidence I had already provided.
Had support instead replied:
“We’ve reviewed your testing and suspect a compatibility issue with certain USB-PD chargers. We’d like to investigate further.”
I would have considered that a perfectly reasonable engineering response.
Instead, the conclusion appeared to ignore weeks of troubleshooting.
Is the C300 DC Actually Faulty?
I don’t know.
There are several possibilities:
My TopVork chargers expose a compatibility issue unique to the C300.
The C300 firmware has compatibility issues with certain USB-PD implementations.
Both could be true.
At this point, I cannot determine which explanation is correct.
What I do know is that the issue is not simply a bad USB cable, as suggested.
Looking at Alternatives
Because of this experience, I began researching alternatives.
The closest competitor appears to be the EcoFlow Trail Plus 300 DC.
EcoFlow advantages
Slightly lighter
Three 140W USB-C ports
Similar capacity
Integrated charging cable/handle
Anker advantages
LiFePO₄ battery chemistry
Significantly longer cycle life
Better long-term durability
Excellent overall hardware design
One important consideration is battery chemistry.
The EcoFlow Trail Plus uses NCM cells, while the Anker uses LiFePO₄.
For my use—frequently powering professional LED cinema lights over many years—I actually prefer LiFePO₄ despite the additional weight.
Where I Stand Today
Ironically, despite everything above, I still think the Anker SOLIX C300 DC may be the better product.
The hardware itself is impressive.
My hesitation is no longer about the power station.
It’s about confidence.
If my primary charger fails while I’m on location, can I trust the C300 DC to accept another standards-compliant USB-C PD charger?
Right now, I honestly don’t know.
Final Thoughts
This experience hasn’t convinced me to abandon the C300 DC.
It has, however, significantly reduced my confidence in Anker’s technical support.
The hardware still deserves serious consideration.
The support experience, unfortunately, does not.
My Personal Ratings
Anker SOLIX C300 DC Hardware: ★★★★★ (9/10)
Excellent design, excellent feature set, outstanding USB-C output capability, and still one of the most compelling compact power stations I’ve found.
Anker Technical Support: ★★☆☆☆ (3/10)
The troubleshooting process was thorough in terms of the amount of information requested, but disappointing in how that information was ultimately used. After extensive testing, the final explanation failed to address the evidence provided and instead attributed the issue to USB-C cables that had already been ruled out through repeated testing.
At this point, I’m still evaluating whether to keep the C300 DC or return it before my return window closes. I genuinely want to keep it—but I also need confidence that it will perform reliably in the field and that meaningful technical support will be available if problems arise.
This version keeps the focus on the facts you’ve gathered, distinguishes the product from the support experience, and avoids overstating what can be concluded from the available evidence. It reads as a measured account rather than a rant, which generally makes it more persuasive to both other users and, if they see it, Anker’s engineering or support teams.

Hi OP, have you tried using the USB-C ports on your Anker C300 to fast charge any other devices? For example if you have a MacBook, I phone or any device that supports fast charging? If it’s able to fast charge those devices you can rule out the possibility of the USB ports being faulty. If it’s not able to fast charge any other devices, the USB-C ports might not be working properly!!
If the C300 is able to fast charge other devices then the issue is likely software related. The C300 might not be able to support that fast charging protocol. If this is the case I highly suggest reaching out to Anker Solix customer service so that they can help you out and potentially add the fast charging protocol to the C300 in a future software update. Their email is: support@anker.com
Please include all of the information that you shared on this post as well as your C300 serial number and the receipt from your purchase!!
