How can I solve this? 1. If the temperature is too high, turn off the unit or stop the load, this will let it cool down. 2. If the temperature is too low for charging, place the unit somewhere warmer or let electrical appliances discharge it for a while. 3. The charging power of the unit is related to the battery level. When the unit starts charging from 0% or is about to be fully charged, it is normal that the charging power is low.Battery Runs Down Too Quickly 1. Please check if there are external high-power electrical appliances. If the power of the connected electrical appliance is about the same as the battery capacity, the battery will run out in about 1 hour. 2. Perform a complete charge and discharge for an SoC calibration.Unable to Fully Charge to 100% Perform three times SoC calibration by doing three complete charges and discharges.Why is my power station input power hopping when i try to charge it? How do i fix this? To fix this, try charging and discharging the unit 3 times. If it still occurs, please provide a video demonstrating the issue and contact us Why does the car charging port not output any power? 1. Confirm whether the DC switch is turned on, and the DC switch will light up to indicate it is on. 2. Try to replace the head of the charger to see whether the cable is faulty 3. If none of the above methods work, provide a video explaining the fault and contact us Why is the car charger not working? 1. Please confirm whether the car cigarette lighter has normal voltage and power output. 2. Try using a solar panel to charge the power station. If the solar panel can be used to charge, it means that there is a problem with the car charger to XT60 cable. Change the cable, and if the solar panel still cannot be used to charge, then contact us Won’t Charge Appliances 1. If charging from an AC outlet, check that the AC switch is turned on. The same goes for DC outlets. 2. If the AC or DC switch is turned on, and it still cannot charge, confirm whether the output power of power station meets the rated charging power of the electrical appliance. 3. When the power from a DC source and car charger is less than 1 watt, the charging power won’t display, but the actual device is charging, try charging another appliance with a larger wattage to see if the charging power displays. 4. When the screen displays an overload alarm, the charging power is too high. Shut down it and leave it to cool down for 30 minutes or try using a low-power device before charging again. If there is still an overload prompt, take a photo or video and contact us 5. The AC switch will automatically turn off after 12 hours if the power of the electrical appliance is less than 10W.Warranty & Return1.All OUPES power stations come with a 3-year warranty and lifetime technical support,1 year warranty for solar panels2.Defective products must be returnedwithin 30 days.The returns should be returned with our original packages. 3.Customers must contact us first for the return address.4.Please contact us through ebay, your message will be replied within 5-15 hours(working days), If you have any problem about the order, please don’t open the return or dispute case immediately, please contact us first, we will try our best to help you, thank you! About OUPES About OUPES Help Program In the heat of a West Texas summer in 2021, Martin, the visionary CEO behind Oupes, found himself holding the results of a company-wide market research initiative. The study, meant to enhance the Oupes product line, inadvertently opened a window into the profound impact of their portable solar power stations on people’s lives. One response, in particular, caught his eye: a family using an Oupes portable power station to keep their child’s medical equipment running during frequent power outages. Martin, deeply moved, knew that this was more than just feedback; it was a calling. He could have used this insight to simply improve product design, but he envisioned a greater opportunity — a chance to empower lives beyond the transactional customer-company relationship. Our Impactful Contributions Joe and Lydia Cook: I came aware of your program while watching Pinballpreparedness@proton youtube channel. He demonstrated your product and was very impressed. He also mentioned your help program and at that time my wife was not on oxygen. She became extremely ill a short time later and requires oxygen 24/7. It was then that I realized if we have grid problems it would be fatal to her. Pinball has repeatedly expressed is opinion of your product and he says it definitely is well made and dependable. From the short time we have had the unit we are very impressed. We have already told most of our prepper friend of how impressed we are with it. A few of them took advantage of your sale . Thank you again.
