Official product questions & technical answers

What devices can the Explorer 300 v2 power?
The Explorer 300 v2 provides up to 300W of AC output with a pure sine wave at 120V, 60Hz. It is well suited for powering small electronics such as laptops, tablets, drones, cameras, portable fans, and lights. Expert Tip: Avoid using high-wattage heating appliances such as coffee makers or hair dr.
Can I use this as a backup power source for my computer?
Yes! One of the standout upgrades in the v2 is the Uninterruptible Power Supply (UPS) feature. When the unit is connected to a wall outlet and your device is plugged into the AC port, it enters "bypass mode". If the grid goes down, the power switches to the internal battery in j.
Why did my Jackery turn off while I was still charging my device?
This is likely due to the Energy Saving Mode. If enabled (switch to the right): The unit will automatically shut down all outputs after 6 hours if the power consumption remains below 25W for AC or 2W for USB/DC ports. To disable: Slide the switch to the left if you need to power low-wattage devic.
How fast can I recharge the Explorer 300 v2?
The Explorer 300 v2 is designed for rapid recovery so you can get back to your adventure faster. Here are the typical recharge times to reach 100% capacity: AC Wall Charging: Approximately 76 minutes using a standard wall outlet. Car Charging (12V): Approximately 242 minutes (about 4 hours) via y.
Is the car charging cable included in the box?
The standard package includes the Jackery Explorer 300 V2 unit, an AC Charging Cable, and the User Manual. Please note that the car charging cable is not included but is available for purchase separately if you plan to charge while on the road.
Can I use the Explorer 300 v2 in the rain or at the beach?
While built for the outdoors, this device is not waterproof or dustproof. It is intended for indoor use or "indoor-like" environments such as tents, RVs, or cabins. Always keep the unit in a cool, dry place and ensure the vents are uncovered to prevent overheating.

What this evidence cannot prove

  • No Find My Generator hands-on test, instrumented load test, teardown, or long-term ownership trial is claimed for this page.
  • Manufacturer specifications may use different fuels, loads, test distances, temperatures, or operating modes. Cross-brand comparisons inherit those differences.

Questions the measurements must answer.

01

Planned measurement

Usable AC energy

Pending

How much of Explorer 300D’s published storage reaches an AC load?

Charge using the manufacturer procedure, allow temperature stabilization, then discharge through a power analyzer at a fixed low load and again near 50% of rated AC output until normal automatic cutoff.

Delivered WhUsable-capacity percentageTest loadCutoff state
02

Planned measurement

Continuous output & overload behavior

Pending

Can the inverter sustain rated loads and respond predictably to short steps?

Apply a correctly rated programmable or resistive load at 25%, 50%, 75%, and 100% of rated output. Log watts, volts, frequency, temperature, fan behavior, faults, and automatic shutdown.

Sustained wattsVoltage and frequencyThermal behaviorProtection response
03

Planned measurement

AC recharge time & input energy

Pending

How long and how much wall energy does a normal full recharge require?

From normal automatic discharge cutoff, recharge to the manufacturer-defined full state with the included AC method. Log input watts, input Wh, elapsed time, charge mode, and ambient temperature.

0–100% timeInput WhPeak input wattsCharge mode
04

Planned measurement

Fan sound & thermal profile

Pending

When do fans become noticeable and how warm does the enclosure become?

At fixed loads, record A-weighted sound at 1 m and 7 m plus non-contact surface temperatures at defined enclosure points. Publish ambient sound and temperature.

dBA by loadFan-on thresholdSurface temperatureAmbient conditions
05

Planned measurement

Transfer / UPS behavior

Pending

If backup transfer is advertised, what interruption does a representative load experience?

Only when the manufacturer advertises the feature, use an isolated, instrumented load and suitable waveform capture to record transfer interruption and output behavior during repeated loss-and-return events.

Transfer timeWaveform eventLoad typePass-through limits

Controlled conditions

  • Record the exact model, serial number, firmware, sample source, and test date before any measurement.
  • Log ambient temperature, humidity, elevation, wind, surface, and background sound for every test block.
  • Record instrument model, range, accuracy, and most recent calibration or verification date.
  • Repeat timing, starting, and sound measurements three times when conditions allow; publish every valid run.
  • Keep original notes, load logs, meter exports, photos, and any excluded-run explanation with the result.

Required equipment class

  • Rated programmable or resistive AC load
  • Bidirectional watt-hour and power analyzer
  • Calibrated sound-level meter
  • Temperature logger or verified non-contact thermometer
  • Waveform capture equipment when transfer-time claims are tested

Safety gate

Use a noncombustible, ventilated test area with battery-rated emergency procedures; stop for swelling, odor, smoke, leakage, abnormal heat, or impact damage.

Testing is for qualified personnel using correctly rated load equipment and the manufacturer’s required grounding, bonding, clearance, and protective-device instructions.

Never connect a generator directly to building wiring or bypass overload, temperature, battery, GFCI, or carbon-monoxide shutdown protection.

Stop a run for unstable voltage or frequency, overheating, fuel or electrolyte leakage, abnormal sound, damaged wiring, or any manufacturer fault indication.

Badge rule: this product receives no “FMG Tested” label or score benefit until a real unit, instruments, conditions, valid runs, raw records, and limitations are documented under the public protocol.
