The power goes out at dinner time, the fridge is warming, and the question is suddenly urgent: jackery explorer 300 vs explorer 500, which one should you buy? Our short verdict: pick the Explorer 500 side if you want the larger stated figures, 512Wh, 500W rated power and 1000W surge, and pick the Explorer 300 side if you want the lighter unit, with 292Wh, 300W rated output and a stated 7.5 lbs. This page compares two Explorer 500 side listings, the station on its own and bundled with a 100W solar panel, against the Explorer 300 side, and walks through what to check before you choose.

Specifications are manufacturer rated as listed, collected 22 October 2026.
What separates the two sides
The model names put the 300 below the 500 in the Jackery line-up, and the listings back that up in three places: how much power each side can output at once, how much energy the battery holds, and how much the unit weighs. The Explorer 500 v2 listing states 500W rated power with a 1000W surge and 512Wh. The bundle listing states the same station figures and adds a 100W solar panel, while its spec table lists 19.3 pounds against 14 lbs in the title. The Explorer 300 listing states 300W rated output with a 600W peak surge and 292Wh. On weight, the 500 v2 title states 14 lbs and the 300 bullets state 7.5 lbs, though each spec table lists a slightly different figure.
Power and battery
Start with the two figures every station listing should state: continuous AC output in watts, and battery capacity in watt-hours. The Explorer 500 v2 listing states 500W rated power and 1000W surge, and the Explorer 300 listing states 300W rated output and 600W peak surge. Treat surge as headroom for motor startup, not as running power. Both sides use LiFePO4 chemistry. The 500 v2 listing states a rating of 6,000 charge cycles, and the 300 listing states over 4,000 charge cycles before reaching 70% capacity. The two cycle claims are worded differently, so cycle life alone does not settle the comparison. Each listing also gives two capacity figures: 512Wh and 518Wh on the 500 side, 292Wh and 293Wh on the 300 side. We rely on the title and bullets.
Protection and carrying
Stations live hard lives: truck beds, campsite tables, porch floors during outages. Look for what the listing states about the shell, the conditions it claims to handle, and any water or dust protection code it names. None of the three listings names a safety certification or an IP rating, so the certification line stays empty for all three. The Explorer 300 package includes a carrying bag, and its bullets describe an integrated handle. The Explorer 500 v2 title states a 14 lbs unit. The bundle package adds a 100W solar panel. Count the AC outlets, USB ports and DC outputs in the listing before anything else. The 500 v2 bullets state two pure sine wave AC outlets, while its spec table lists one total outlet. The 300 bullets state 2 AC outlets, a 100W USB-C PD port, 2 USB-A ports and a 120W car port.
What to check before you buy
Read the title and the bullets first, then the spec table, and trust the title and bullets when they disagree. Watch for a listing that names a different brand or model than the headline promises, and for a listing that turns out to be an accessory rather than the station itself. A warranty counts only when it states a concrete term: the Explorer 500 v2 listings state a 5 year manufacturer warranty, and the Explorer 300 listing states a 2 year manufacturer warranty. When the figures you need are missing, the listing is incomplete, not the product.

The title and bullets state 512Wh, 500W rated power, 1000W surge, a LiFePO4 battery rated for 6,000 cycles and two pure sine wave AC outlets, plus a 100W solar panel in the package. The spec table disagrees on weight: it lists 19.3 pounds against 14 lbs in the title, and it gives 518Wh in the item type name against 512Wh in the title and bullets, so we trust the title and bullets. The maker claims a 0 to 80 percent charge in 52 minutes from an AC wall outlet.

How we scored them
The Solar Score weighs performance, build, value, safety and warranty. For power stations, safety means the protections each listing names, such as stated certifications, battery management features and weather protection codes. All three listings state a manufacturer warranty, so all three earn warranty points, with the longer stated term earning more. None names a safety certification, so none earns safety points. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Jackery Explorer 500 v2 Bundle | 9.6 | 30 | 20 | 21 | 0 | 4 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best jackery explorer 300 vs explorer 500

The bundle listing adds a 100W solar panel to the same station figures.

| Stated 500W output and 1000W surge | The Explorer 500 v2 |
| A 100W panel in the package | The Explorer 500 v2 bundle |

Sizing Notes
- Match the station’s continuous AC output to the combined watts of the loads you plan to run at once.
- Match the battery capacity in watt-hours to how long those loads need to run between charges.
- Match any solar panel’s voltage and watts to the solar input range the station listing states.
- Check the stated weight and dimensions against where the station will live, from campsite to closet shelf.
Frequently Asked Questions
What is the main difference between the Jackery Explorer 300 and 500?
The 500 is the larger step in the line-up. The Explorer 500 v2 listing states 512Wh, 500W rated power and 1000W surge, while the Explorer 300 listing states 292Wh, 300W rated output and 600W peak surge.
Can these stations charge from solar panels?
The Explorer 500 v2 listing states that the station supports solar panels, sold separately, and 12V car charging. The Explorer 300 listing says a solar panel is optional and pairs it with Jackery panels. The bundle listing includes a 100W solar panel in the package. Confirm the panel input range before buying other panels.
How do I size a station to my loads?
Add up the watts of everything you plan to run at once and compare that with the station’s stated continuous output, then compare the run time you need with the stated battery capacity.
Is the bigger station always the better buy?
No. More capacity usually means more size and weight, so a bigger station you leave at home helps less than a smaller one you actually carry. Match the station to the loads, not to the headline number.
What does the warranty cover on these listings?
The Explorer 500 v2 listings state a 5 year manufacturer warranty and the Explorer 300 listing states a 2 year manufacturer warranty. Read the maker’s terms for what each covers, since the listings give only the length.
