There are several popular portable power stations available for under $300. These compact devices can be great for powering small appliances and electronics when camping outdoors or during a power outage at home. The Jackery Explorer 240, EcoFlow River 2, and Bluetti EB3A are three top picks in this ultra-affordable price range.
The Jackery, EcoFlow, and Bluetti models reviewed here all offer decent battery storage capacities between 185Wh and 230Wh. This gives them the ability to recharge smartphones multiple times, run mini coolers, power small medical devices, and more. With standard AC outlets and various DC ports, you can plug in and charge up most small devices.
These portable power stations are light enough for backpacking and camping trips when you need to power things like phones, cameras, and camping lights. They also work well for emergency power during a blackout. When the grid goes down, you can connect lights, a router or modem, and other essentials.
While they don’t store as much energy as larger and more expensive stations, these sub-$300 models provide sufficient power for basic needs during short-term outages or off-grid excursions. We put them to the test to see which one combines the best performance, features, and overall value under $300.
Testing Criteria
When comparing portable power stations, there are several key specifications and performance metrics that indicate how well a model will perform in real-world use. Our evaluations looked closely at the following important criteria:
- Battery capacity – The watt-hours (Wh) rating indicates the total amount of power the station’s battery pack can store and deliver. More Wh means longer runtimes for devices.
- Power output – The continuous and peak wattage ratings determine which devices the station can support. Models with higher outputs can power more demanding appliances.
- Recharge time – How quickly the station can fully recharge is crucial for restoring power between uses. Faster is better when you need the station back up and running.
- Display features – Convenience factors like an intuitive interface, clear status screens, and visibility in sunlight make a big usability difference.
- Value – The overall combination of performance, features, and price point. The “sweet spot” that maximizes affordability and utility.
By evaluating portable power stations across these metrics, we can better understand the real-world strengths and limitations of each model when it comes to powering devices during outages or outdoor excursions. Selecting a station that excels in the areas most important for your needs ensures the best experience.
Battery Capacity Test
Test setup
We fully charged each power station and then tested continuous run time with a 40W box fan, representing a 0.2C discharge load on the batteries. This allowed us to compare real-world usable capacity.
Results
The Jackery Explorer 240 lasted the longest, delivering over 230Wh to the fan, exceeding its rated capacity. The EcoFlow River 2 shut down after 185Wh delivered, and the Bluetti EB3A lasted 188Wh, both a bit under their rated capacities.
The Jackery Explorer 240 performed the best in this test, running the fan over 5 hours before shutting down, better than its advertised 228Wh capacity. The EcoFlow and Bluetti units fell slightly short of their rated capacities but still provided decent runtimes.
Analysis
The Jackery Explorer 240 performed the best in this test, running the fan over 5 hours before shutting down, better than its advertised 228Wh capacity. The EcoFlow and Bluetti units fell slightly short of their rated capacities but still provided decent runtimes.
Recharge Time Test
Test setup
Starting from an empty 0% state, we connected and charged up all three power stations simultaneously to compare their recharge times.
This allowed us to evaluate how quickly each station can recharge when depleted and get back up and running. Fast recharge speed is an important consideration for portable power stations.
Results
The Bluetti reached an 80% charge in just 33 minutes before the EcoFlow hit the same level at 45 minutes in. The Jackery took a full 60 minutes to reach only 23% charge.
The Bluetti and EcoFlow power stations were both fully recharged in about 1 hour. Meanwhile, the Jackery Explorer 240 took well over 5 hours to reach a full charge from empty.
Analysis
The results show a clear advantage in recharge speed for the Bluetti and EcoFlow models compared to the Jackery. Getting back to a full charge in only an hour allows more flexibility and usage cycles versus having to wait many hours to recharge.
The Jackery’s very slow recharge time is a significant limitation and disadvantage compared to the other two options. Fast recharge capability is a useful feature that provides more value for a portable power station in real-world use.
Display Features
The displays on the power stations offer important at-a-glance information and control of the unit. We evaluated the usability and aesthetics of the displays.
Jackery Explorer 240 Display
The Jackery Explorer 240 has a monochrome LCD display that is rather basic. It shows the battery percentage, input and output status, and overload protection warning. The small screen only displays text and lacks any graphics. It works well for glancing at the battery level but doesn’t add much visual appeal to the overall product.
EcoFlow River 2 Display
EcoFlow upgraded the display on the River 2 model. It is a black and white LCD screen with added details like the battery capacity in watt-hours, charging speed in watts, and estimated time remaining. There are simple menu buttons to toggle screen views. Overall the display is an improvement over Jackery but still fairly plain in appearance.
Bluetti EB3A Display
One area where Bluetti stands out is the full color touchscreen display on the EB3A. The high resolution panel is bright and aesthetically pleasing. It shows precise battery and power readings, has intuitive menus and settings, and even displays live power consumption charts. The responsive touch controls make navigating simple. Of the tested models, Bluetti clearly has the most functional and user-friendly display.
Power Output Test
We tested the power output capabilities of each model by attempting to operate a 300 watt portable induction cooker and an 800 watt electric kettle:
-
The Jackery Explorer 240 powered the induction cooker for 30 seconds before overload protection shut it down.
-
The EcoFlow River 2 was able to run the induction cooker continuously without issue.
-
The Bluetti EB3A powered the induction cooker but only by lowering the output voltage.
While the Bluetti EB3A could not produce the cooker’s full 300 watts, its larger battery capacity allowed it to at least produce a reduced voltage temporarily to run the appliance. This indicates the Bluetti may be capable of powering more devices simultaneously compared to the Jackery and EcoFlow, even if some devices do not operate at peak performance.
Overall, the EcoFlow River 2 provided the best continuous 300 watt power output. But the Bluetti EB3A showed versatility to deliver lower power to more demanding devices. The Jackery Explorer 240 clearly lacked the output capability of the other two models.
