Jackery Explorer 300 v2 Review (2026): 8 Pounds, 288Wh, and a 100W Solar Ceiling
Affiliate disclosure: This post may contain affiliate links. As an Amazon Associate I earn from qualifying purchases. We couldn’t verify an Amazon listing for the Explorer 300 v2 specifically, so the button goes to Jackery’s product page. No brand pays for placement.
How we evaluated: WildJoule has not bench-tested this unit, and we found no independent hands-on reviews of the v2 yet. Specs come from Jackery’s US Explorer 300 v2 page, checked October 24, 2026. The 100 W solar figure comes from US retailer spec sheets because Jackery’s page doesn’t state it. Where sources conflict, we say so. Runtime figures are our estimates.
This Jackery Explorer 300 v2 review is short on hype because the unit is simple: 288 Wh of LiFePO4, 300 W of pure sine AC (600 W surge), two AC outlets, a 100 W USB-C port, and an 8.16 lb body you can carry with one hand. It recharges from the wall in about 76 minutes. It replaces the Explorer 300 Plus in Jackery’s US lineup, and the 240 v2 page now shows sold out.
Quick verdict
Buy it if you want the lightest practical LiFePO4 box for phones, laptops, camera batteries, a fan or a CPAP night, and you’ll charge it mostly from the wall or car. Skip it if you want to run anything with a heating element, rely on solar, or want app control. The EcoFlow River 3 is the closest rival, with Wi-Fi and a slightly faster wall charge but less capacity.
To be clear about my footing: I don’t have an Explorer 300 v2, and I’m not going to describe carrying one up a trail. I pay attention to small units because during the kind of short, frequent outages I’m used to, a box this size quietly handles most of what matters: light, phone, internet. I read Jackery’s page closely, cross-checked retailers, and ran the runtime numbers myself.
Jackery Explorer 300 v2 review: specs at a glance
| Spec | Jackery Explorer 300 v2 | What it means |
|---|---|---|
| Capacity | 288 Wh LiFePO4 (19.2 V, 15 Ah) | About 245 Wh at the AC outlets (our 85% estimate) |
| Cycle rating | 4,000 cycles to 70%+ | Years of regular use |
| AC output | 300 W continuous, 600 W surge, 2 outlets | Electronics and small fans, not kettles |
| DC ports | USB-C 100 W, USB-C 15 W, USB-A 15 W, 12 V/10 A car port | One fast USB-C for a laptop |
| Wall charging | About 76 min to full, 80% in about 1 hour | Jackery doesn’t publish the input wattage |
| Solar | 100 W max via DC8020 (retailer figure) | About 9.5 h with Jackery’s 40 W panel |
| Car charging | 12 V, about 4 hours | Sources conflict on whether the cable is included |
| UPS | Yes; about 20 ms per Jackery’s FAQ (other figures exist) | Fine for a router or modem |
| Weight / warranty | 8.16 lb; 9.09 × 6.02 × 6.6 in; 3+2 years (the extra 2 when bought from Jackery) | No app mentioned by Jackery |
What it runs, and for how long
300 W continuous covers laptops, phones, tablets, a small TV, a fan, LED lights, a router and modem, and most CPAP machines without a heated humidifier. It won’t run a coffee maker, hair dryer, toaster or microwave; Jackery’s own FAQ steers you away from heating appliances.
With about 245 Wh usable by our estimate: a 60 W laptop runs around 4 hours; a router and modem at 20 W together about 12 hours; a 40 W CPAP without humidifier roughly 6 hours. Phones are almost free by comparison, at around 15 Wh per full charge, so you’re looking at a dozen or more. A 12 V cooler at 35 W average off the car port lasts about 7 hours. For sizing a CPAP setup properly, see our best power station for CPAP picks.
Charging: great from the wall, slow from the sun
About 76 minutes to full from the wall is quick for this size. Solar is the weak spot. Retailers list 100 W maximum through Jackery’s DC8020 port, and Jackery itself quotes about 9.5 hours with its 40 W SolarSaga panel. Even with a 100 W panel in perfect sun, you’re looking at three-plus hours in the real world. If solar is your main charging plan, the Explorer 300 v2 isn’t the right box; look at our camping power guide for setups built around panels.
Jackery Explorer 300 v2 review: the trade-offs
Thin published specs. Jackery doesn’t list the AC input wattage or the solar voltage range, and its page gives two different UPS figures (about 20 ms in the FAQ, ≤0.01 s elsewhere). Retailers fill some gaps, and one even mislabels the model. None of that makes the unit bad, but it makes comparing it harder.
No app, as far as we can find. Jackery doesn’t mention one for the 300 v2, and no retailer does either. The 240 v2 had app support, so this looks like a deliberate cut.
No Amazon listing we could confirm. Amazon listings for “Explorer 300” mostly show the older 292–293 Wh model or the 300 Plus. Check the capacity on any listing: the v2 is 288 Wh LiFePO4.
Explorer 300 v2 vs the alternatives
The EcoFlow River 3 (245 Wh, 300 W, 7.8 lb) charges in about an hour and has Wi-Fi, but less capacity. The River 3 Plus doubles output to 600 W and expands. The Anker SOLIX C300 DC drops AC entirely in exchange for USB-C charging both ways. Our River 3 vs Anker C300 comparison covers that pair in detail.
Where this Jackery Explorer 300 v2 review lands: a light, honest electronics box with a weak solar input. Buy it to keep devices running through short outages and road trips.
Frequently asked questions

It’s a 288 Wh LiFePO4 unit with 300 W output and roughly 76-minute wall charging, sold in place of the Explorer 300 Plus. The original Explorer 300 (292 Wh) used a different lithium chemistry.
