The Jackery Explorer 300 sold by Jackery US today stores 292Wh of LiFePO4 and has two 120V AC outlets rated 300W, one 100W USB-C, two USB-A and a 120W car port, at 7.5 lb. The Jackery Explorer 300D stores 288Wh of LiFePO4 but has no AC outlet at all: three USB-C ports at 140W, 140W and 65W, a 15W USB-A and a 12V car port, at 5.51 lb, with no fan. If everything you charge has a USB-C or a 12V plug, the 300D is the lighter, silent box; if anything on your list has a wall plug, only the Explorer 300 runs it.
Below: what separates them with numbers, a 20-second calculator for your own gear, eight modeled situations, a third Jackery option with AC and a UPS, and what we could and couldn’t verify.
Same battery size and the same LiFePO4 chemistry rated for 4,000 cycles to 70%. The Explorer 300 adds two AC outlets; the 300D trades them for three fast USB-C ports, a fan-free case and 2 lb less weight. They are $80 apart today.

The five differences that decide it
Both are Jackery stations with about 290Wh of LiFePO4 rated for 4,000 cycles to 70%, a 12V car port and 100W of solar input. 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 300D. AC loads need the Explorer 300; the 300D runs only USB and 12V gear.
Practically a tie: the Explorer 300 holds only 1% more than the 300D.

The price gap, in numbers
The Jackery Explorer 300 costs $80 more than the Jackery Explorer 300D and adds 4Wh: that is $20 per extra Wh, against $0.73 per Wh for the 300D.
Prices refresh daily from Jackery US.Both are rated for 4,000 cycles to 70% and hold about the same energy, so the lifetime line follows the price. What you pay for is the AC inverter on the Explorer 300, or the faster USB-C, lower weight and fan-free case of the 300D. Both prices are refreshed daily by our price engine and move often.
The third option: the Jackery Explorer 300 v2 at $299
Jackery Explorer 300 v2: $299 today
Jackery’s newer AC model of the same size: 288Wh of LiFePO4, 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. It keeps the AC outlets the 300D lacks and publishes the figures the Explorer 300 page leaves out. Jackery US listed it as sold out on our October 31, 2026 check. Our Explorer 300 v2 review goes deeper. See the 300 v2 at Jackery.
Eight modeled situations, worked out
Same formula as the calculator above: 85% of the rated capacity. Where a device has a wall plug, only the Explorer 300 can run it.
Charging laptops at camp
About the same number of charges, since the batteries match. The 300D charges two laptops at 140W each; the Explorer 300 has one 100W USB-C. Our count allows about 15% for conversion losses.
Starlink Mini off-grid
Both run it for most of an evening. Jackery quotes about 10 hours of Starlink Mini for the 300D, which powers it from USB-C or 12V without an inverter.
CPAP for one night
Neither covers a full night. The Explorer 300 runs the CPAP’s AC brick; the 300D needs the maker’s 12V cable. Jackery doesn’t recommend its stations for medical devices.
Wi-Fi router through an outage
Both keep it up for most of a day. The Explorer 300 takes the router’s wall adapter; the 300D needs a 12V or USB-C cable for it. Jackery publishes no switchover time for either, so plug the router in once the power is out.
12V cooler on a camping weekend
Both have a 120W car port and run it for an afternoon.
A TV or a fan with a wall plug
Only the Explorer 300 runs it, up to 300W in total. The 300D has no AC outlet.
Refill from a 100W panel
About the same: both top out at 100W of solar. Jackery quotes 80% in about 2.8 h on the Explorer 300 with a 100W panel; the 300D takes 16 to 28V on its DC8020 port, so check your panel’s voltage.
Carrying it
The 300D is 2 lb lighter and smaller: 4.67 × 4.73 × 7.20 in, with a strap-style handle that doubles as its 140W USB-C cable.

Every port, side by side
Explorer 300
Explorer 300D
Practical consequence: the Explorer 300 has two AC outlets, one 100W USB-C, two USB-A and a 120W car port. The 300D has no AC, but three USB-C ports (140W, 140W and 65W), a 15W USB-A and the same 12V car port; with all five busy, the manual drops them to 65W, 65W, 30W, 15W and 120W. Its carry strap is a 140W USB-C cable. Neither has DC5521 barrels or a battery port.

Neither takes an extra battery.Does it work as a UPS? Jackery publishes no switchover time for the Jackery Explorer 300. The Jackery Explorer 300D has no AC output, so it can’t act as a UPS.
Does it have a fast charging mode? The Jackery Explorer 300D reaches 80% in about an hour from a 140W USB-C charger of your own, per Jackery. No wall-charging figure is published for this Jackery Explorer 300.
Is there a built-in light? The Jackery Explorer 300D has an LED light with light and SOS modes, per its manual.
Can you add a battery later? Neither the Jackery Explorer 300 nor the Jackery Explorer 300D takes an extra battery.
Warranty and support
The Jackery Explorer 300D carries 3 years plus 2, the Jackery Explorer 300 2 years plus 1. On both, the extension is automatic on Jackery.com orders and by online registration otherwise.
Same 4,000-cycle rating to 70%.Subject to each brand’s warranty terms and eligibility.
Jackery rates both at 4,000 cycles to 70%, about 11 years at one full cycle a day. Calendar aging and heat also reduce capacity, so read the rating as a ceiling.
- If you buy either one outside Jackery.com, register it online to add its extra years.
- Keep the order confirmation: Jackery asks for proof of purchase for warranty claims.
What reviewers report
We have not lab-tested these two units, and we found no independent hands-on test of either from an outlet we accept: reviews of the original 2020 lithium-ion Explorer 300 don’t apply to the LiFePO4 version, and the 300D’s UK coverage we could find was launch news or blocked. This page uses Jackery’s official figures for both.
Practical limits before you buy
- The 300D has no AC outlet. Anything with a wall plug, from a TV to a CPAP brick, won’t run on it.
- The Explorer 300 stops at 300W. Jackery says it shuts off once the total passes 300W.
- No wall charger comes with the 300D. It charges through USB-C; its 80% in about an hour needs a 140W USB-C charger of your own.
- The 300D’s solar input tops out at 28V. Panels must stay between 16 and 28V open-circuit on its DC8020 port.
- 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 model.
- Energy Saving Mode on the 300D cuts all outputs after 6 hours below 2W, on by default.
- Jackery doesn’t recommend its stations for medical devices or data servers.
