Anker SOLIX C300 vs DJI Power 500
The Anker SOLIX C300 (288Wh) and DJI Power 500 (512Wh) sit in different weight classes. The real question: do your power needs justify the larger unit, or would you be overpaying for capacity that sits unused? The Power 500 has a slight edge, but the margin is close enough that your use case should break the tie.
The Power 500's 512Wh keeps a fridge going for 3 hours. The SOLIX C300's 288Wh manages 2 hours. The bigger unit rides out a full weekend outage. The smaller one needs a recharge by Saturday night. But if your actual use case is camping, tailgating, or keeping devices charged, the SOLIX C300 does the job at 9.1 lbs and $240 — no overkill, no regret.
Pick the Power 500 if your primary use is cpap overnight. Go with the SOLIX C300 if you need the heavier-duty specs for demanding loads. Most buyers overlook this: the Power 500 costs ~$0.18/kWh over its full lifespan, which adds up significantly over years of regular use. Keep scrolling for the full breakdown. The scenario verdicts below hold a few surprises.

What the Specs Don't Tell You
Hidden gotchas and advantages we spotted that you won't find on the product page.
Surge Power: Inverter Quality Indicator
AdvantageThe SOLIX C300 has a 2× surge-to-continuous ratio vs the Power 500's 1×. A higher ratio (≥2×) means the inverter handles motor startup surges better. That's critical for fridges, AC compressors, and power tools that briefly draw 2-3× their rated wattage. The Power 500 may trip when starting these appliances even though its continuous wattage looks sufficient.
UPS Speed: line-interactive (<10ms) vs standby (<20ms)
NoteThe SOLIX C300 switches to battery in 10ms (line-interactive (<10ms)), while the Power 500 takes 20ms (standby (<20ms)). Safe for desktop PCs, routers, and CPAP machines. NAS drives are protected. This matters if you're using it as a home UPS for always-on equipment.
Warranty Value Comparison
NoteThe SOLIX C300 gives you 20.8 years of warranty per $1,000 spent, vs the Power 500's 13.9 years. That's 1.5× more coverage per dollar. An underrated factor if you're keeping this unit for years.
Battery Lifespan in Real Years
NoteThe Power 500 is rated for 4,000 cycles vs 3,000. In real life: at daily use, that's 11 vs 8.2 years. At weekend use (twice a week), it's 38 vs 29 years. After hitting the cycle limit, the battery doesn't die. It drops to ~80% original capacity, which is still very usable.
Your Life, Your Pick
We ran the math on six real-world scenarios. Here's which unit survives your actual life.

Brand Trust
Anker
Ecosystem
7-8 SOLIX portable power stations across C-series (compact) and F-series (flagship), plus the X1 home energy system
Support
US-based support. Historically known for incredible no-hassle replacements, but recent reports describe AI-driven support agents giving generic responses and complex return logistics for heavy units (hazmat shipping). The Anker brand reputation is still strong, but SOLIX-specific support quality is trending down.
Community
Moderate — active Reddit (r/Anker, r/AnkerSOLIXCommunity) and growing. Benefits from Anker's massive consumer electronics brand awareness.
App Experience
Rated 4.5/5 iOS (~1,100 ratings) · 4.3/5 Android
Unique Strength
Parent brand trust from Anker's consumer electronics dominance. InfiniPower technology for long cycle life. Gen 2 lineup offers exceptional $/Wh value — some of the best in the market.
Worth Knowing
Support quality appears to be declining from its historically excellent level. Firmware updates have removed features without warning. Expansion ecosystem is smaller than EcoFlow's.
DJI
Ecosystem
New entrant (2024) — 4 power station models: Power 500, Power 1000 V2, Power 1000 Mini, Power 2000
Support
Leveraging DJI's established global support and repair center network from the drone business. Generally positive reputation inherited from drone operations, but limited power-station-specific track record.
Community
No dedicated power station community yet. Discussions happen within r/dji (~250K members, mostly drone users). Very small power-specific presence on Facebook and forums.
App Experience
Rated 3.5/5 iOS and Android (DJI Home app ratings reflect entire DJI ecosystem including drones/cameras, not power-station-specific). Users report the on-device screen is more reliable than the app.
Unique Strength
Quietest operation in the category (~26dB). Fastest wall-charging speeds (~56 min for V2). 700+ battery patents from drone R&D. SDC ports for ultra-fast DJI drone charging. Premium industrial design and build quality. LFP batteries rated for 4,000+ cycles.
Worth Knowing
Very new to the power station space — only ~2 years of track record. No built-in solar charge controller (requires separate proprietary adapter). SDC ports are proprietary to DJI ecosystem. Limited "plug-and-play" value for non-DJI users. No expansion battery ecosystem yet.
DJI positions itself as a mid-to-premium brand with stronger support infrastructure, while Anker competes on value. The question is whether the DJI ecosystem and support premium is worth it for your use case.
Growth Path
SOLIX C300
🔒 Closed SystemClosed system. What you buy is what you get. If your needs outgrow 288Wh, you'll need to purchase an entirely new unit.
Accepts up to 100W of solar. Limited to a single portable panel.
Adequate ports for most setups, but heavy users may want a power strip.
Power 500
🔒 Closed SystemClosed system. What you buy is what you get. If your needs outgrow 512Wh, you'll need to purchase an entirely new unit.
Accepts up to 300W of solar. Limited to a single portable panel.
Adequate ports for most setups, but heavy users may want a power strip.
Neither unit supports expansion. What you buy is what you get. Make sure the capacity you choose today covers your needs for the next 3-5 years.
The Bottom Line
The full picture comes down to this. The Power 500 edges ahead on our overall analysis, but the margin is narrow enough that your specific use case should drive the decision. Review the scenario verdicts above — if the SOLIX C300 wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the SOLIX C300 nor the Power 500 feels like the right fit, your power needs probably sit outside what these two target. If you're planning whole-home backup or running power-hungry appliances (electric heaters, window AC), you'll want a larger system in the 3,000–5,000Wh range with expansion battery support. Prices on portable power stations fluctuate frequently. Both Anker and DJI discount regularly, so check the current price before committing. Prime Day and Black Friday pricing typically drops 20-30%.
Frequently Asked Questions
SOLIX C300 vs Power 500 — answered by our testing team.
Q.Is the Power 500 worth $119 more than the SOLIX C300?
The short answer: yes, if you'll actually use the extra capability. The Power 500 costs $119 more, but that premium buys you 224Wh more battery capacity (that's 1 extra hours of running a mini-fridge); 700W higher AC output (opening the door to more demanding appliances); a longer-lasting battery rated for 4,000 cycles — that's 11 years at daily use; 200W faster solar charging for quicker off-grid recovery. On a cost-per-watt-hour basis, you're paying $0.70/Wh vs $0.83/Wh. Factor in cycle life and the math flips: the Power 500 costs $0.18/kWh over its lifetime vs $0.28/kWh. The "expensive" unit is actually cheaper to own. For regular use, we'd pay the premium.
Q."4,000 vs 3,000 cycles" — what does that actually mean for me?
In real years: the Power 500 (4,000 cycles) lasts 11.0 years at daily use, 38 years at weekend use (twice a week), or 167 years at twice-monthly camping trips. The SOLIX C300 (3,000 cycles): 8.2 years daily, 29 years weekends, or 125 years twice-monthly. What most people miss: hitting the cycle limit doesn't kill your battery. Capacity drops to about 80%. Your 512Wh unit becomes a ~410Wh unit. Still very usable. For weekend users, both batteries will outlast the warranty by years.
Q.Is Anker or DJI more reliable for long-term ownership?
Both brands have strengths and trade-offs. Anker: 5-year warranty standard on portable stations, 10-year on home energy systems. Historically very reliable, though some recent firmware updates have altered product functionality without notice or rollback option. DJI: 3-5 years depending on model. DJI has a reasonable track record from drone products. Too early for comprehensive power station warranty data. One piece of advice from the power station community: regardless of brand, buy from Costco or Amazon. Their return policies provide a safety net that manufacturer warranties alone can't match, especially for a product you'll rely on in emergencies. Both brands use LFP (lithium iron phosphate) batteries in their current lineup, the most proven chemistry for longevity and safety.
Q.Bottom line: should I buy the SOLIX C300 or the Power 500?
We'd pay the premium for the Power 500. Yes, it costs more. The capability jump is real: you're stepping into a tier that handles appliances the base model can't start. The SOLIX C300 is still solid if budget is the priority, but the Power 500 will leave you less likely to wish you'd "gone bigger" six months from now. That regret costs more than the price difference.
