PORTABLE POWER · BUYING DECISIONS
A small power station can be useful without being a miniature whole-home backup system. Match it to a clearly defined set of devices.
Around 288 Wh, rated output can differ by a factor of two. The Jackery Explorer 300 v2 lists 300 W; Elite 30 V2 and RIVER 3 Plus list 600 W. A larger inverter does not double battery runtime.

A hypothetical 40 W load running for four hours consumes 160 Wh before losses and the power station’s own consumption. A 200 W load running for four hours needs 800 Wh before losses. Both may fit a 300 W output ceiling while only the first is within the nominal energy of this compact group. Output compatibility and energy sufficiency must both pass.
These are arithmetic examples, not runtime tests. Low-power loads can be especially sensitive to idle draw, automatic shutdown settings and whether you use AC or a suitable DC connection. Check those details for your intended device.
Jackery’s technical table lists 8.16 lb for the 300 v2. BLUETTI lists 4.3 kg for Elite 30 V2, converted here to 9.48 lb. RIVER 3 Plus is listed at 10.4 lb in our source record. The difference matters most when you carry the unit regularly; cables and chargers add to the bag weight.
The Explorer 300 v2 is not the older 300 Plus, and RIVER 3 Plus is not the base RIVER 3 or a Max battery bundle. Check the exact name on the order page.
Move beyond this class when measured consumption, desired duration or the required reserve exceeds the available energy. Do not use an advertised lifting or boost number as proof a high-power appliance will operate normally. A larger battery still needs the right output, ports and startup capability.
Write down each device, its running demand, hours of use and connection type. Verify compatibility in the manual, check low-load shutdown behavior, then compare the complete delivered price. This shortlist is for comparison, not certification of medical-device or uninterrupted-power suitability.

Retailer prose uses 293 Wh and a 300 Plus image filename. Jackery’s current Explorer 300 v2 is a distinct 288 Wh model. Confirm model and included charging cable against SKU 21-0001-000364 before ordering; do not substitute the older Explorer 300 or 300 Plus.

288 Wh / 600 W US base unit. Its higher output ceiling does not imply more stored energy than another 288 Wh model.
