300 Watt Power Stations Compared: 4 Small Models, Real Specs

Four small 300 Wh class stations compared on their official specs: the EcoFlow RIVER 3 Plus, Anker SOLIX C300, Jackery Explorer 300 v2 and BLUETTI Elite 30 V2. They hold almost the same energy (286–288 Wh): about 4 hours of a 60 W laptop, a day of a Wi-Fi router, or one night of a CPAP with a heated humidifier. The real choice is output: the EcoFlow and the BLUETTI are rated for 600 W, the Anker and the Jackery for 300 W. The Jackery is the lightest at 8.2 lb.

How we compared: we don’t physically test products and no brand paid for a place on this page. Every figure comes from the manufacturer’s official U.S. product page, checked on October 29, 2026. There are no affiliate links on this page. See How We Research.

“300 watt” can mean two things

A “300 watt power station” can mean about 300 watt-hours of capacity or about 300 watts of output. All four below store about 300 Wh; two deliver 300 W and two deliver 600 W. Watts vs Watt-Hours explains the difference with a real spec sheet.

Specs checked on October 29, 2026 from each manufacturer’s U.S. product page. “SurgePad” (Anker), “X-Boost” (EcoFlow) and “lifting power” (BLUETTI) are each brand’s way of running some devices above the rated output, under conditions that vary by brand; they’re not the same as a higher rating. Check the manual. We don’t list prices: they change often.

What the differences mean

Capacity: a tie, and what it runs

With 286–288 Wh, these four deliver about 245 Wh from their AC outlets (our 0.85 allowance for inverter losses) or about 259 Wh from their 12 V and USB ports (0.90). In practice:

Device About how long
Laptop drawing 60 W About 4 hours
Wi-Fi router drawing 10 W About 24 hours
12V fridge (Dometic CFX3 45 on a 90°F day, from the 12 V port) About 21 hours
CPAP without humidifier (ResMed’s measurement, 56 Wh per night) About 4.6 nights
CPAP with heated humidifier and heated tube (272 Wh per night) Just under 1 night

For your own CPAP settings, use our CPAP Battery Calculator. The fridge and CPAP figures come from our camping guide and CPAP guide. This class is for small electronics and short trips; for a fridge over a weekend, look at the 1,000 Wh class.

Output: 300 W or 600 W

This is the line that decides what you can plug in at all. 300 W covers laptops, phones, lights, a CPAP, a router or a small fan. 600 W adds room for things like a small TV and a laptop together, or a few devices at once. Neither runs a coffee maker, microwave or kettle at full power: those draw around 1,500 W (see our appliance guide).

Weight: all light, one lightest

Chart of watt-hours per pound for four small power stations: Jackery Explorer 300 v2 35.3, Anker SOLIX C300 31.6, BLUETTI Elite 30 V2 30.4, EcoFlow RIVER 3 Plus 27.5

From 8.16 lb (Jackery) to 10.4 lb (EcoFlow). All four are easy to carry; the difference is about 2 lb.

Charging: about an hour from the wall

The EcoFlow lists a full charge in 60 minutes, the BLUETTI 80% in 45 minutes and the Anker 80% in 50 minutes. Jackery’s page lists a 15 A AC input for the 300 v2 but no clear charging time for this model. For solar, the EcoFlow accepts the most (220 W), the Anker the least (100 W). The Anker and the BLUETTI also accept only up to 28 V of panel voltage, so check the panel’s open-circuit voltage before connecting it. Our charging guide explains these limits.

USB-C: the port that matters most in this class

Many people use a small station mainly for laptops and phones. The Anker and the BLUETTI list a 140 W USB-C port; the EcoFlow and the Jackery 100 W. Charging a laptop from USB-C directly skips the inverter and its losses.

Cycle life

The EcoFlow and the BLUETTI are rated for 3,000 cycles to 80% of capacity, the Jackery 4,000 to 70%, and we didn’t find a rating on the Anker page. A rating to 70% is a lower bar than one to 80%, so the numbers aren’t directly comparable.

Which one fits which use

Based only on the specs above:

The lightest station Jackery Explorer 300 v2: 8.16 lb
600 W output and the most solar input EcoFlow RIVER 3 Plus: 600 W, 220 W solar, expandable to 858 Wh

Safety: Use the chargers and cables the manufacturer approves, keep the station within the temperatures in its manual and keep its vents clear. For a CPAP or other medical equipment, check the device maker’s guidance and talk to your doctor before relying on a battery.
