Overview
The OUPES Mega 1 (model S1) is OUPES's current 1 kWh unit and the successor slot to the Exodus 1200 on Amazon. Per its Amazon listing it pairs a 1,024 Wh LFP pack with 2,000 W of pure sine AC output (4,500 W surge), two 100 W USB-C PD ports, four QC3.0 USB-A ports and 12 V DC outputs, and accepts up to two B2 extra batteries for 5,120 Wh total. OUPES claims 0 to 80% in 36 minutes on AC and 26 minutes with AC plus solar, a sub-20 ms UPS, a 3,500+ cycle rating to 80%, Bluetooth app control and by-pass charging.
Variant note: Mega 1 (S1) standalone. Distinct from the Mega 1 Lite (S1 Lite), the B2 extra battery, and Mega 1 solar bundles. Separate from the OUPES Exodus 1200 and 2400, which are indexed separately.
Data note: Indexed from its Amazon listing only; OUPES's product page is linked for reference and its hero image shows four AC outlets on the front, consistent with the listing's outlet count. Weight 27.8 lb and dimensions 15.1 x 9.1 x 11.6 in converted from the listing. The listing's 'Engine Type: 4 Stroke', '79 cc' and 'electric start' rows are Amazon category template noise and are ignored. upsEpsMode is unknown because the only source is a '<20ms UPS' marketing line with no documented switchover behaviour. carChargingSupported left null: an included 'Cigarette Lighter to Anderson Cable' suggests it but no car-charging input is stated.
