  • QuestionWith a 50” tv, how long could I plug in and watch on a fully charged generator?

    Asked by csett8.

    • Answer Dear customer, thank you for your interest in Jackery products. The Explorer 290, with a battery capacity of 290Wh and an output power of 200W, is capable of powering a 50" tv. To estimate the runtime, we use a straightforward calculation: multiply the battery capacity by 0.85 and then divide by the device's power consumption. Generally speaking, a 50" tv will use between 70 (LED TV) to 150 (LCD TV) watts. The Explorer 290 could theoretically seperately run a 50" tv for approximately 1.6-3.5 hours (calculated as 290×0.85÷150 to 290×0.85÷70). Please consider this an approximate figure, as actual runtime is influenced by the exact power requirements of your tv, additional connected devices, and more. Please check the power requirements of your device. It's crucial to ensure that the total power draw from all devices connected does not surpass the Explorer 290's 200W output limit to prevent system overload. For a precise calculation or further assistance, our customer service team is at your disposal (Customer Service: [email protected] / +1-888-502-2236 Weekdays 9AM to 5PM PST).

  • QuestionI have an enclosed gas fireplace that can keep our house above freezing even when we don't use our furnace. In the event of an electrical outage, I need a battery operated generator that will keep the fan going. What do you suggest?

    Asked by donk.

    • Answer I used the Jackery 290 for a 120, heater. It lasted 2 hours. To run your fireplace fan you would need a bigger one, and (depending on the length of time you dont have power) possibly 2 batteries on rotation. I would get at least the Jackery 1000 or 1500 for the purpose pf the fireplace fan.

  • QuestionHow long can this power a standard box fan? Same question for a space heater.

    Asked by Anonymous.

    • Answer Dear Customer, Thanks for reaching out to us regarding this question. This Explorer 290 can power a standrad box fan around 3 to 8.6 hours. Becasue the lowest running watts of a space heater is more than 200W(the continuous output watts of Explorer 290), this item can not power a space heater. The Explorer 880 and 1500 are recommended to you to run a space heater. Should you have other questions or concerns, feel free to contact our customer service. Thank you for your support.

  • Questioncan i connect a EcoTank Photo ET-8500 Wireless printer to this, and how long will it last

    Asked by printer.

    • Answer Thank you for your question. Yes — you can connect an Epson EcoTank Photo ET-8500 wireless printer to the Jackery Explorer 290 (E290), as long as the printer’s power draw stays within the unit’s limits: 🔌 E290 Specs • Capacity: ≈292 Wh • AC Output: 200 W continuous • Surge Peak: 400 W Most wireless printers like the EcoTank ET-8500 draw well under 200 W during printing, so the E290 can safely power it. Estimated Runtime If your printer draws around 50–100 W while printing: • ~50 W load: ~4–5 hours • ~100 W load: ~2–2.5 hours 📌 In most cases, printers only draw significant power when actively printing — in standby or idle mode, they use much less, so the unit can last even longer. If you tell me your printer’s actual wattage while printing, I can give a more precise estimate.

  • QuestionWill it charge an electric golf cart?

    Asked by Bill.

    • Answer Thank you for your question. The Jackery Explorer 290 (E290) cannot charge an electric golf cart. Electric golf carts require high-capacity batteries and high charging currents that are far beyond the E290’s 110 V AC output (max 200 W) and battery capacity (≈292 Wh). The E290 is designed for small electronics and low-wattage appliances, not large vehicle batteries.

  • Questioncan it run a Pioneer XDJ XZ all in one dj controller. and for how long?

    Asked by Tibil.

    • Answer Thank you for your question. The Jackery Explorer 290 (E290) can power a Pioneer XDJ-XZ all-in-one DJ controller, as long as the controller’s power draw stays within the station’s output limits: 🔌 E290 AC Output 200 W surge 400W Most DJ controllers like the Pioneer XDJ-XZ draw significantly less than 200 W, so the Explorer 290 should run it without issue. Estimated Runtime To estimate how long it will run: If your controller draws about 50 W, a 292 Wh battery could last roughly 4–5 hours. Actual runtime can vary based on: • Volume levels and effects being used • Whether you also power speakers or other gear • Efficiency and actual power draw of your equipment If you tell me your controller’s actual wattage (listed on the label or manual), I can give a more accurate estimate.
