Same size battery; the real question is whether you need the app or the second outlet.
The Jackery Explorer 300 Jackery US sells today is the LiFePO4 version: 292Wh, 300W from two 120V outlets, a 100W USB-C, two USB-A and a 120W car port, at 7.5 lb. The Jackery Explorer 300 Plus stored 288Wh of LiFePO4 and delivered 300W with a 600W surge from one outlet, had two USB-C ports (100W and 15W), Wi-Fi and Bluetooth app control and a 20ms EPS, at 8.27 lb; Jackery US no longer lists it. If you own a 300 Plus, the new Explorer 300 adds an outlet, not capacity; if you are buying now, the Explorer 300 is the one on sale, with fewer published specs.
Below: what separates them with numbers, a 20-second calculator for your own gear, eight modeled situations, a third Jackery option with a published UPS time, and what published tests found on the 300 Plus.
Two LiFePO4 stations of about 290Wh that both stop at 300W. The Explorer 300 has two AC outlets and weighs 7.5 lb; the 300 Plus had one outlet, an app, a published 600W surge and a 20ms EPS, at 8.27 lb. Jackery US sells the Explorer 300; the 300 Plus page was gone on our November 1, 2026 check.

The five differences that decide it
Both use LiFePO4 cells, stop at 300W, have a 100W USB-C and a 12V car port, and take about 100W of solar. These five gaps decide it.
Will it run your setup? Check in 20 seconds
Estimates use 85% usable capacity and 70% of rated solar output. Real results vary with temperature, inverter load, shade and appliance cycling. Fridge and freezer watts are daily averages and do not include compressor startup surges.
Runtime by appliance, one at a time
Simple energy estimates, not measured runtimes: about 248Wh usable on the Explorer 300 and 245Wh on the 300 Plus. Trusted Reviews measured 253Wh out of a 300 Plus at a 50W load.
Practically a tie: the Explorer 300 holds only 1% more than the 300 Plus.

What the current options cost today
Jackery US removed the 300 Plus page. If a seller still has a new one, check that Jackery’s warranty applies. The lifetime line divides today’s price by 4,000 cycles of 292Wh, a simplified ceiling. Prices move often.
The third option: the Jackery Explorer 300 v2 at $299
Jackery Explorer 300 v2: $299 today
If you want the 300 Plus’s published specs with the Explorer 300’s two outlets, the Explorer 300 v2 holds 288Wh of LiFePO4 and delivers 300W from two 120V outlets with a 600W surge, a 100W USB-C, a 12V car port, a 20ms switchover and a full wall charge in about 76 minutes, at 8.16 lb. Jackery US listed it as sold out on our November 1, 2026 check. Our Explorer 300 v2 review goes deeper, and our 300 v2 vs 300 Plus comparison covers that pair. See the 300 v2 at Jackery.
Eight modeled situations, worked out
Same formula as the calculator above: 85% of the rated capacity, no extra battery.
Wi-Fi router through an outage
Both keep it up for most of a day. The 300 Plus switches to battery within 20ms in EPS mode, so the router can stay plugged in through it; Jackery publishes no switchover time for this Explorer 300.
CPAP for one night
Neither covers a full 8-hour night: about six hours on either. Jackery doesn’t recommend its stations for medical devices.
Charging laptops at camp
About the same, since the batteries match. Macworld charged an M3 MacBook Air by 47% in 30 minutes from the 300 Plus. Our count allows about 15% for conversion losses.
A TV and a fan, both with wall plugs
Only the Explorer 300 takes both plugs directly, for about two hours. The 300 Plus has one outlet, so you need a power strip and must stay under 300W in total.
12V cooler on a camping weekend
Both have a 12V car port and run it for an afternoon. Plan a recharge for an overnight run.
Refill from a 100W panel
About the same. The 300 Plus takes solar through its USB-C port with a DC8020 to USB-C adapter sold separately; Macworld saw only about 30W from a 40W panel. Jackery quotes 80% in about 2.8 h on the Explorer 300 with a 100W panel.
Refill from the wall before a storm
Jackery and Trusted Reviews both give the 300 Plus about two hours. Jackery publishes no wall-charging time for this Explorer 300; the 2.5 h on its page belongs to the original model.
Carrying it
Both go in one hand; the Explorer 300 is about 0.8 lb lighter. Trusted Reviews liked the 300 Plus’s fold-down handle.
Eight more differences, the spec sheet and the box

Weight: 7.5 lb for the Explorer 300 and 8.27 lb for the 300 Plus. Dimensions: 9.1 × 6.1 × 6.6 in for the 300 Plus; Jackery publishes none for this version of the Explorer 300. Everything else is in the sheet below.

Practical consequence: the Explorer 300 has two AC outlets, one 100W USB-C, two USB-A and a 120W car port. The 300 Plus has one AC outlet, a 100W USB-C that is also its charging and solar input, a 15W USB-C, a 15W USB-A and a 12V car port; besides the 100W port, its other USB ports share 24W.

What reviewers report
We have not lab-tested these two units. The 300 Plus side draws on three published tests; Trusted Reviews tested a UK unit, so its outlet and wall-charging findings are 230V. We found no independent hands-on test of the LiFePO4 Explorer 300; reviews of the original 2020 lithium-ion Explorer 300 don’t apply to its battery, so we leave them out.

Practical limits before you buy
- Jackery US no longer sells the 300 Plus. Its product page now returns an error.
- Both stop at 300W. A coffee maker, a kettle or a hair dryer won’t run on either.

- The 300 Plus takes solar through USB-C, with a DC8020 to USB-C adapter Jackery sold separately.
- Check which Explorer 300 you get. Jackery sells the LiFePO4 version under the original 2020 listing, and much of that page still describes the old 293Wh model.
- Jackery publishes few figures for this Explorer 300: no surge, UPS time, wall-charging power, noise, size or temperature range.
- Jackery doesn’t recommend its stations for medical devices or data servers.

Related comparisons and reviews
How we compared and sources
Research-based comparison. We have not lab-tested these units. Explorer 300 specs come from Jackery’s US page for the LiFePO4 version. Explorer 300 Plus specs come from its US page archived on May 20, 2026 and Jackery’s US spec feed for the model. Usage observations are attributed to named reviewers. Checked on November 1, 2026.
- Specs: Jackery US, Explorer 300 (LiFePO4 version); Jackery US, Explorer 300 Plus (archived May 20, 2026) and Jackery’s US spec feed for the 300 Plus, read on November 1, 2026.
- The 300 Plus’s US page now returns an error. Its EPS time comes from its user manual, which Jackery serves only in a 230V edition; we use that manual for the switchover and auto-off behavior only, and the US spec feed for 120V figures. The feed rates the 300 Plus at 3,000 cycles to 80% while the page FAQ says 4,000 to 70%; we show both.
- Jackery US sells the LiFePO4 Explorer 300 under its original 2020 listing; we use only the figures that page gives for the new version.
- Reviewer reports on the 300 Plus: Trusted Reviews, David Ludlow, January 2024, UK unit, RV.com, Kraig Becker, September 2023, Macworld, Thomas Bergbold, June 2024.
- Runtime = capacity × 0.85 ÷ watts. Solar harvest = min(panel watts, max input) × sun hours × 0.70. Cost per lifetime kWh = price ÷ (cycles × capacity in kWh).
About 290Wh and 300W each: two outlets at 7.5 lb, or one outlet with an app and a 20ms EPS at 8.27 lb. Jackery US no longer sells the 300 Plus.
