Jackery Explorer 300 Plus Review: Best Mini Power Station?

The short answer: the Jackery Explorer 300 Plus (288Wh) is discontinued, so buy one of its current rivals instead. The EcoFlow River 3 (245Wh, 7.8 lb, one-hour recharge) is the best match for most people, and Jackery's current Explorer 300 is a close second. Both cost about what the 300 Plus did.

What the Explorer 300 Plus Offered

Specs are cross-checked against Jackery's Explorer 300 Plus product page (checked earlier; the unit is no longer sold new).

It was a compact mini station for phones, a laptop, and small electronics over a weekend. The 300W ceiling ruled out anything power-hungry.

Why It's Discontinued

Jackery has refreshed its entry-level lineup. If you find new old stock at a steep discount the hardware is sound LiFePO4, but you may not get a manufacturer warranty on old stock, so verify before buying.

What to Buy Instead

OutdoorGearLab tested Jackery's Explorer 300 and measured 260Wh of usable energy; StorageReview measured 210Wh on the River 3. See the full EcoFlow River 3 review and the Bluetti AC70 review. For more options at every price, see our budget power station roundup and best power stations under $500.

How the Category Has Moved

The big change since the 300 Plus is charging speed: the River 3 refills in about an hour versus roughly two hours for the 300 Plus (and roughly four for Jackery's current Explorer 300 in OutdoorGearLab's test). Cost per Wh is still high in this class: about $0.98 for the River 3, against about $0.47 for the 768Wh AC70. If you only need phones and a laptop, the small ones win on weight; if you want a mini fridge or a CPAP, step up to the AC70 or a 1,000Wh unit.

What a Mini Station Actually Runs

Using the 260Wh and 210Wh measured by independent testers:

• CPAP at 40W: about 5-6.5 hours, which is less than one night
• Phone charging (about 15Wh per charge): about 14-17 charges
• Laptop (about 55Wh per charge): about 4-4.7 charges
• LED lantern (5W): about 42-52 hours

For overnight CPAP use, read our CPAP guide.

If You Already Own One

There is no need to replace a working unit; LiFePO4 batteries in this size class are typically rated for 3,000+ cycles, and light use means most owners are far from end of life. Follow our maintenance guide and replace it only when it stops meeting your needs.

Frequently Asked Questions

Is it safe to buy a used Jackery Explorer 300 Plus?

LiFePO4 is inherently safe and long-lasting, but a used unit has no manufacturer warranty and you cannot verify its cycle count from a listing. If the price is not well below a new River 3 ($195-$239), buy new.

What replaced the Explorer 300 Plus in Jackery's lineup?

Jackery's current mini unit is the Explorer 300, which OutdoorGearLab tested at 260Wh usable. Check Jackery's site for the current model list, since names change with each refresh.

Can a mini power station run a CPAP all night?

Not at a typical 40W draw: 260Wh is about 6.5 hours of usable energy at best. A larger unit such as the Bluetti AC70 covers about two nights.
