Introduction to the EZVIZ PS300 Portable Power Station and its key features
EZVIZ PS300 Portable Power Station (CS-CN032)is a compact, grab-and-go energy solution designed to keep phones, tablets, laptops and small appliances powered when youre away from a wall outlet. With a 313 Wh NCM lithium-ion battery, 300 W continuous AC output, a 60 W USB-C Power Delivery port and a selection of other outputs, the PS300 is built for weekend campers, remote workers, tailgaters and anyone who wants a lightweight emergency backup. It pairs a straightforward user interface (smart LCD) and an integrated LED light with a comprehensive Battery Management System (BMS) for practical day-to-day use and peace of mind.
Detailed description of specifications and benefits
The PS300 is small but thoughtfully specified. Key specifications and the benefits they deliver include:
- Battery: 313 Wh NCM lithium-ion— This capacity is solid for a compact unit. NCM (nickel cobalt manganese) chemistry offers a favorable energy density and a typical cycle life of around 1,000 cycles to ~80% capacity, which makes the PS300 a capable mid-term companion for regular light-to-moderate use.
- AC output: 300 W continuous, ~500 W surge— Two AC outlets let you run laptops, small kitchen appliances, CPAP machines (carefully check device startup current), fans, LED lamps and other low-to-moderate power items. The surge capability handles short motor start-ups and startup draws, but the continuous 300 W limit rules out high-wattage heaters, full-size microwaves or heavy power tools.
- USB-C Power Delivery (up to 60 W)— A 60 W PD USB-C port can fast-charge many laptops, tablets and modern phones. That level of PD is a competitive advantage versus some compact stations that only offer 30 W or less.
- Multiple ports— In addition to USB-C, the PS300 includes 3× USB-A ports (each up to 2.4 A), 2× AC outlets and a 12 V car outlet (≈120 W max). These outputs make it easy to charge multiple devices simultaneously: phones, cameras, a portable fridge, lighting and a laptop all at once, within the total power limits.
- Flexible recharging— Recharge via AC adapter, USB-C input, car port or compatible solar panels (DC 12–24 V, ≈48 W max). Typical recharge times: USB-C ≈5–6 hours, AC adapter ≈7–10 hours, car ≈10–12 hours and solar depending on panel conditions (~7–8 hours under ideal sun). The variety of recharge methods increases versatility on trips or during prolonged outages.
- Smart LCD and LED light— The LCD shows remaining capacity, input/output power and warnings so you can manage consumption. A built-in LED light gives emergency illumination without adding another device to pack.
- Safety and BMS— Over-voltage, over-current, over-temperature, overload, short-circuit and low-voltage protections are all handled by the built-in BMS. These protections help protect the battery, connected devices and users.
- Dimensions: 145 × 212 × 212 mm — small footprint and easy to stow in a car or backpack compartment.
- Net weight: ≈3.61 kg — light enough for most people to carry short distances.
- Operating temperature: charge 0 °C–40 °C; discharge −10 °C–40 °C — check local conditions before use.
- Warranty: not specified here — verify warranty terms with the retailer or manufacturer before purchase.
Use cases and scenarios where the PS300 excels
The PS300 is particularly well-matched to users who need a lightweight, multiport power station rather than a high-capacity or heavy-duty generator. Situations where the PS300 shines include:
For a weekend camper, the PS300 can run LED lighting, charge phones and cameras, power a compact electric cooler and keep a laptop topped up for occasional use. Its compact size and multiple recharge options (including solar) make it easy to integrate into a weekend setup.
Digital nomads and field workers who need a reliable laptop charge will appreciate the 60 W USB-C PD port. Combined with phone charging from USB-A and the AC outlets for a monitor or small printer, the PS300 supports a portable workstation for several hours depending on device draw.
During power outages the PS300 can keep essential devices alive: charge phones, run LED lighting, power routers/modems to maintain internet and handle small medical devices that fall within the 300 W envelope. Its not a whole-house solution, but it fills a valuable role for essential support and short-term mobility.
Event photographers, drone pilots and creatives benefit from multiple outlets to charge cameras, batteries and laptops. The units portability and quick PD charging reduce downtime between shoots.
- Smartphone (10–15 Wh): many full charges from a single PS300 cycle.
- Laptop (typical 30–60 W draw): roughly 3–6 hours depending on draw and charging efficiencies (a 60 W draw would give ~5 hours in ideal conditions).
- Mini fridge (30–50 W average): several hours; initial compressor startup should be checked against the 500 W surge capability.
- LED lighting and small electronics: extended runtime when multiple low-draw devices run simultaneously.
Note: actual runtimes vary with device efficiency, inverter losses and environmental conditions. Always check your devices power draw and allow margin for safety.
Comparisons with similar products in the market
In the compact portable power station category, common competitors include models from Jackery, Anker and EcoFlow with similar capacities (around 200400 Wh). Key comparison points:
- Capacity and weight— The PS300 at 313 Wh and ≈3.61 kg sits in the mid-range: larger than ultra-light 200 Wh units but much easier to carry than 500 Wh+ options. This is a practical middle ground for many users.
- AC output— 300 W continuous is typical for this capacity class. Some competitors may offer similar continuous power but differ in surge capability or inverter efficiency. If you need consistent high continuous power, a larger unit would be necessary.
- USB-C PD power— The 60 W PD port is a differentiator versus many compact stations that offer only 30 W PD or none at all. This makes the PS300 better for charging mid-range laptops without relying on the AC inverter.
- Price-value balance— With a suggested price of $329 and a cost price noted here of $263.99, the PS300 is competitive. Alternatives in the market may be priced similarly, but the combination of 313 Wh, 60 W PD and multiple outputs places the PS300 as a strong value option for those who want a compact but capable station.
- Recharging flexibility— Multi-method recharging (AC, USB-C, car, solar) is comparable with other mainstream units. The PS300s solar input (≈48 W) is practical for topping up during the day, though high-power panel arrays will charge faster on larger stations.
Customer testimonials and reviews
Official and verified customer reviews are the best way to gauge real-world performance. If you are researching the PS300, look for retailer and forum reviews that address long-term reliability, real run-time figures and battery health over months of use. While no specific customer quotes are provided here, common themes buyers often cite for similar models include:
- Appreciation for compact size and reasonable weight for travel.
- High satisfaction with USB-C PD capability when it can directly charge laptops faster and more efficiently than the inverter route.
- Requests for clearer warranty information and regional compliance details (CE/UKCA where relevant).
If you can, inspect user photos and measured run-time tests posted by purchasers to confirm how the PS300 handles your exact devices.
Conclusion: why the EZVIZ PS300 is a great choice
The EZVIZ PS300 Portable Power Station delivers a strong mix of portability, useful capacity and practical ports that make it a versatile choice for a wide range of users. Its 313 Wh NCM battery with ~1,000-cycle life, 300 W AC output and 60 W USB-C PD bring together the essentials for mobile work, weekend adventures and short-term emergency backup without the bulk of larger stations.
Strengths include a solid balance of capacity vs. weight, a good selection of outputs for common devices, flexible recharge options (including solar) and comprehensive BMS protections. Limitations are inherent to the size: the PS300 isnt intended to run high-wattage appliances for long periods and buyers should verify warranty and local compliance details before purchasing.
Overall, for users seeking a compact, multiport power station that can reliably handle phones, laptops, lights and small appliances while being easy to transport, the EZVIZ PS300 represents a balanced and cost-effective option in its category. Check product labeling and manuals for full safety guidance and confirm retailer warranty terms before finalising your purchase.
