It didn't take long to arrive but it was shipped from my home state so it didn't have to travel far. Unboxing it, I found three power cables and a service manual. The manual is not very detailed and the English is sketchy so I'm assuming it was printed using a translation program. When I got it out of the box, read the manual, and turned it on, it had about 60% battery so I charged it on low input (there is a high input and low input). It charged quickly and came to 100%. I tried it to see how long the battery power would last. I gave it a draw of about 120-130 watts of power and it lasted almost 9 hours. Pretty impressive for the first run. When it was out of power, it gave an error code. I turned the unit off, then back on, and then plugged it in and it charged to 100% again without any problems. So far, this seems to be a reasonably good backup power supply. If you're using it for emergencies or for camping, outdoor activities, I think it would be good. However, if you're looking for something to keep you off grid or for everyday use, this is probably too lightweight with not enough KWH to do that. It is much lighter than I thought it would be. It's easy to move around, portable, but the plastic isn't really top quality. I wouldn't expect this to take a hard fall or nocking around too much. I seriously doubt it is water or weather, resistant. I haven't tried to use it as a UPS but the manual does say you can do that. There are two different settings for charging the unit, (high and low). It's a little complicated to change that setting but if you have a lower amp circuit and need to charge the unit without blowing a fuse or tripping a breaker, it can be helpful. It switches the input from about 1200 watts to around 600 watts but it takes longer to charge on lower power. My only gripe is that at low or high input the fan runs while it is charging... always runs while it is charging... the fan on low power charge isn't very strong or loud, but it is there, for two hours or more... so... it can get annoying. At some point I'll try some more features of this unit and add to this review, but for now, I'd say it's a good product and will do what I need. Review: Reliable Power When You Need It – OUPES Mega 1 Review - Reliable Power When You Need It – OUPES Mega 1 Review I purchased the OUPES Mega 1 Portable Power Station last month, and it has already proven to be one of the most reliable and user-friendly power stations I’ve used. With its 2000W continuous output (4500W peak) and 1024Wh LiFePO4 battery, it delivers dependable power for a variety of needs—from home backup during outages to powering devices while camping or using it with an RV. ✅ Key Highlights from My Experience: Easy Setup: Right out of the box, the setup was quick and intuitive. The user interface is simple and clear, and getting it running took only a few minutes. Solid Build & Expandable: The unit feels well-built and is expandable up to 5120Wh, which gives peace of mind for longer trips or extended outages. Solar Charging Compatibility: I’ve tested it with solar panels, and the 800W solar input is impressive. It’s compatible with standard MC4 solar connectors, making integration smooth with my existing gear. Fast AC Charging: The 1400W AC input recharges the battery quickly, which is a great feature if you need to top up the unit between uses. ⚠️ Minor Issue: The only hiccup I’ve encountered is with the Wi-Fi connectivity via the app. It struggles to connect consistently over Wi-Fi. However, Bluetooth works reliably, so I’ve been able to monitor and control the system effectively using that method. Final Thoughts: Overall, I’m very pleased with the OUPES Mega 1. It offers an excellent balance of power capacity, ease of use, and expandability, making it a smart investment for emergency preparedness and outdoor adventures. If OUPES improves the Wi-Fi functionality in a future firmware or app update, this would be a near-perfect solution for portable energy needs. Highly recommended for anyone looking for a powerful, solar-ready, and user-friendly power station. ## Features - REVOLUTIONARY FAST-CHARGING TECHNOLOGY: Experience industry-leading recharge speeds with 0-80% capacity in just 36 minutes via AC, or an unprecedented 26 minutes when combining AC and solar inputs simultaneously – 3X faster than conventional power stations. - MODULAR EXPANSION CAPABILITY: Create a custom power ecosystem by connecting up to two B2 Extra Batteries, scaling your capacity from 1024Wh to an impressive 5120Wh without additional inverters or complex wiring – perfect for growing power needs. - PROFESSIONAL-GRADE POWER DELIVERY: Delivering consistent 2000W continuous output (4500W surge) through premium AC outlets with pure sine wave technology to safely power sensitive electronics, professional equipment, and high-demand appliances without voltage fluctuations. - RELIABLE UPS TECHNOLOGY: Professional-grade <20ms transfer time during power outages protects critical equipment like servers, medical devices, and workstations from data loss and hardware damage. - NEXT-GENERATION LiFePO4 BATTERY ARCHITECTURE: Featuring advanced lithium iron phosphate cells with 3500+ lifecycle rating and superior thermal stability, delivering consistent performance across thousands of charge cycles while maintaining 80% capacity after years of heavy use. - INTELLIGENT POWER MANAGEMENT SYSTEM: The proprietary smart BMS automatically balances cells, prevents overcharging/over-discharging, and maintains optimal operating temperatures for maximum efficiency and longevity of your investment. - SMART APP CONTROL: Monitor and manage every aspect of your power station remotely via Bluetooth connectivity – track real-time power consumption, customize output settings, etc. - COMPREHENSIVE DEVICE COMPATIBILITY ECOSYSTEM: Power everything from smartphones to power tools with versatile outputs including dual 100W USB-C PD ports, four QC3.0 USB-A ports, specialized 12V DC outputs, and robust AC outlets – all managed by intelligent power distribution. - ENGINEERED FOR PROFESSIONAL DEPLOYMENT: Built with premium components and rigorous quality control standards to withstand daily professional use in demanding environments from film production sites and mobile offices to emergency response scenarios and off-grid research stations. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DG8JQNS4 | | Additional Features | 0-80% Charge in 36 Mins, <20ms UPS, Expand Capacity to Huge 5kWh, Smart APP Control, Supports By-pass Charging | | Best Sellers Rank | #25,293 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #117 in Outdoor Generators | | Brand | OUPES | | Brand Name | OUPES | | Color | Black | | Current Rating | 10 A | | Customer Reviews | 4.5 out of 5 stars 1,483 Reviews | | Engine Displacement | 79 cubic centimeters | | Engine Power Maximum | 4.5 KW | | Engine Type | 4 Stroke | | Frequency | 60 hertz | | Fuel Type | Electric | | Ignition System Type | electric start | | Included Components | 1x AC Charging Cable, 1x Car to Anderson Charging Cable, 1x MC4 to Anderson Charging Cable, 1x Mega 1 Power Station (2000W/1024Wh), 1x User Manual | | Item Dimensions L x W x H | 15.1"L x 9.1"W x 11.6"H | | Item Highlight | Expandable to 5kWh, 36 Mins to 80% Charge, LiFePO4 Solar Generator, UPS Backup, Built-in MPPT, 100W PD USB-C, APP Control | | Item Weight | 27.8 pounds | | Manufacturer | SHENZHEN WEI PENG SHIJI TECHNOLOGY CO., LTD | | Manufacturer Part Number | S1 | | Material Type | Lithium Iron Phosphate | | Model Name | Mega 1 | | Model Number | S1 | | Number of Items | 1 | | Output Wattage | 2000 | | Power Source | Battery Powered | | Recommended Uses For Product | Camping & road trips, Home backup, Off-grid power, Power outages & emergencies | | Running Wattage | 2000 watts | | Runtime | 1 hour | | Starting Wattage | 4500 watts | | Total Power Outlets | 4 | | Unit Count | 1 Count | | Voltage | 120 volts_of_alternating_current | | Warranty Description | 5-year warranty | | Wattage | 1024 watt-hours | ## Product Details - **Brand:** OUPES - **Fuel Type:** Electric - **Item Weight:** 27.8 pounds - **Output Wattage:** 2000 - **Power Source:** Battery Powered - **Recommended Uses For Product:** Camping & road trips, Home backup, Off-grid power, Power outages & emergencies - **Voltage:** 120 volts_of_alternating_current - **Wattage:** 1024 watt-hours ## Images ![Mega 1 Portable Power Station 1024Wh 2000W (4500W Surge) - Image 1](https://m.media-amazon.com/images/I/81MfuZQsaDL.jpg) ## Available Options This product comes in different **Set** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ So far, so good *by C***C on November 23, 2025* I received this battery in good order, well packaged, and in new condition.

Updated after excellent support. *by G***G on June 17, 2025* Update #2: I have tried some various testing and it is working completely as I expected. I found a great use also for smaller units like this as a buffer for power devices. If you have a large inrush or occasional run device that overloads a circuit when kicking on (think commercial coffee pot or air compressor), put this in between the circuit and the device. Set the charge to a slow rate and it will handle the surge then recharge slowly over the next few minutes. Also, support was genuinely helpful when required at the beginning. I work in the backup power world and would recommend this unit, and have done so, to anyone looking. Update September 14, 2025. When helping my daughter move I found a fatal design flaw. The charge cable is proprietary. I am in Chicago and cannot easily source a replacement charge cable. If we had not found that a very helpful person packing had put it in a box in the U-Haul truck (causing us to unpack some). I am using the unit to temporarily power a chest freezer for the overnight move, I needed the cable a few hours after packing. This causes the review to drop to 3 stars and is something I hope the designers will correct in the future. Update July 27, 2025. They replaced the unit quickly once it was determined to be an issue. The new unit has been test and it works great. I adjusted the review to 4 stars based on the outstanding support. It would have had 5 had I not had to go through the process. Update: June 23, 2025. I messaged support and received emails and a call back within a day or two. They gave me instructions for a test that, due to my own schedule, I just completed. It is suspected that there is a BMS Management issue in the unit, and they have asked me to return it to them. I am anticipating a shipping label to return the unit. They indicated that they would replace the unit once they receive this one. So far support has been outstanding! Issues happen with electronics, I get it. The key is can you get the help you need when you have negative experiences. So far with OUPES they have been proactive to resolve my issues. I will update again once the next step is complete. I increased my rating to 3 stars based on support alone. I hope a replacement will push this to 5 stars! I have had this unit for less than two months. Before I left for a camping trip with it, the first real test was to run it down and recharge it to know how much time it would take on AC and with Eco-Worth 100W panels (2). The unit was discharged and will not turn back on. There has been no response from plugging it in, nothing. There has also been no response from connecting solar panels. At this point, it is an expensive boat anchor. I have submitted a message to their customer support, and I hope they can help me reset this unit so that it works again. I am testing the unit, and the support I received before I can change my review from a 1-star to anything higher. I own a consulting company for much larger systems and wanted to try consumer-grade products. So far, others have been worth the purchase, but this one is a wait-and-see. ## Frequently Bought Together - OUPES Mega 1 Portable Power Station 2000W (4500W Peak), 1024Wh LiFePO4 Battery Generator with 1400W AC Charging & 800W Solar Charging, Expandable to 5120Wh, for Home, Power Outages, Camping & RVs - ECO-WORTHY Solar Connectors Y Branch Parallel PV Adapter Cable Wire Plug Tool Kit for Solar Panel(M/FF+F/MM) - ECO-WORTHY 2pcs 100 Watt Solar Panels Monocrystalline Solar Panel for 12V/24V Battery RV Marine Boat and Other Off-Grid Applications, 2-Pack 100W --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/656512130-mega-1-portable-power-station-1024wh-2000w-4500w-surge](https://www.desertcart.jp/products/656512130-mega-1-portable-power-station-1024wh-2000w-4500w-surge) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-23*
