OUPES Power Station Lineup (2026): Mega vs Exodus vs Guardian

OUPES sells three lines of power stations: Exodus (small boxes that cannot be expanded), Mega (1kWh to 5kWh, expandable with add-on batteries) and Guardian (its 240V home backup unit). On November 11, 2026, OUPES's US store had only five OUPES power station models in stock: the Exodus 350, Exodus 700, Mega 1 Lite, Mega 1 and Guardian 6000 V2. The Mega 2, Mega 2 Pro, Mega 3, Mega 5 and the older Exodus models were all marked sold out.

Amazon, where OUPES runs its own storefront (sold by OUPES-US), was cheaper than OUPES's store for all four smaller models that day: $189.99 for the Exodus 350 (OUPES: $299), $294.49 for the Exodus 700 ($399), $489 for the Mega 1 Lite ($599) and $529 for the Mega 1 ($699). For most buyers the pick is the Mega 1: 1,024Wh, 2,000W and an extra-battery port for $40 more than the Lite. Buy the Guardian 6000 V2 ($2,699 at OUPES) only if you need 240V.

How we built this guide: it is based on OUPES's US store (its power station collection and product listings, read November 11, 2026), the user manuals OUPES publishes for the Exodus 350, Exodus 700, Mega 1 Lite, Mega 1 and Mega 5, OUPES's Amazon US listings, our own reviews of the Guardian 6000 V2 and Mega 2, and the runtime arithmetic shown below. Prices move often, so treat ours as approximate.

Every OUPES power station in one table

The last column is a quick sizing check: hours of a 150W outage-essentials load (a fridge, router, lights and phones averaged together, from our appliance power guide). It uses the 0.85 factor in OUPES's own runtime FAQ: usable Wh = rated Wh x 0.85, and hours = usable Wh / 150, so the Mega 1 gives 1,024 x 0.85 / 150 = about 5.8 hours.

Sources: OUPES's US power station collection and its product listings, read November 11, 2026; the spec tables in the five user manuals linked above; OUPES's June 2025 Mega vs Exodus comparison for the Mega 3's weight; our Mega 2 and Guardian 6000 V2 reviews for those models; and OUPES's Amazon US listings, read the same day. OUPES's collection page also advertised lower promotional prices than its listings (for example $509 for the Mega 1 and $1,899 for the Guardian 6000 V2), so if you buy direct, look for a code at checkout.

What do Exodus, Mega, Lite, Pro and Guardian mean?

• Exodus is OUPES's small portable line. The current Exodus 350 and 700 hold 288Wh and 576Wh of LiFePO4, have a 140W USB-C port and connect to OUPES's app, and switch to battery in 10ms or less when the grid drops. No Exodus takes an extra battery, and solar input tops out at 240W and 35V, which means a single panel or panels wired in parallel, not in series.
• Mega is the expandable line, from 1kWh to 5kWh. The Mega 1, Mega 2 and Mega 3 share the 2,048Wh B2 Extra Battery; the Mega 5 uses the larger B5. Every Mega is 120V only, and the Mega 1, Mega 1 Lite, Mega 2 and Mega 2 Pro list a UPS switchover of 20ms or less, against 10ms for the Exodus.
• Lite means no extra-battery port. The Mega 1 Lite has the same 1,024Wh battery, 2,000W inverter, 1,400W wall charging and 800W solar input as the Mega 1, but its manual shows no expansion port. It swaps the Mega 1's two 100W USB-C ports for two 140W ones, drops two USB-A ports and the two small DC barrel outputs, and weighs about 1 lb less.
• Pro (Mega 2 Pro, April 2026) replaced the Mega 2 with a 1,000W two-way Anderson DC port and 140W USB-C, but cut rated solar input from 2,100W to 1,000W. Our Mega 2 review compares the two.
• Guardian is OUPES's 240V home backup unit. The Guardian 6000 V2 gives 6,000W at 240V from L14-30R and 14-50R outlets, takes up to eight 4,608Wh G5 batteries and rolls on two wheels. It replaced the original Guardian 6000, now sold out.

Which OUPES should you buy for your use?

Phones, laptops and a CPAP on a camping trip: Exodus 350

The Exodus 350 is a 9.2 lb, 288Wh box with 350W of AC output (600W peak), a 140W USB-C port and a 10ms UPS that passes up to 600W, for $189.99 on Amazon. It runs a CPAP without its heated humidifier (about 20W) for about 12 hours (288 x 0.85 / 20), a CPAP with the humidifier on (about 55W) for about 4.5 hours, and a 60W laptop charge for about 4 hours. It charges at 200W from the wall, about 1.5 hours by arithmetic. Against the Jackery Explorer 300 (292Wh, 300W, $289 on Amazon the same day), it costs about $100 less for 50W more output.

A mini fridge or a full night of CPAP: Exodus 700

The Exodus 700 doubles the battery to 576Wh, with 700W of output (1,200W peak), a UPS that passes up to 960W and 400W wall charging (about 1.5 hours by arithmetic), at 13.9 lb and $294.49 on Amazon. It runs a CPAP with a heated humidifier for about 8.9 hours, a full night, and a mini fridge (ENERGY STAR's median of 680Wh a day) for about 17 hours. A full-size fridge is a stretch: Honda puts its start-up draw at about 1,200W, right at this unit's peak. OUPES says a 240W panel takes it from 0 to 80% in about 2 hours.

1kWh for outages and road trips: Mega 1 Lite or Mega 1

Both have 1,024Wh, 2,000W of output (4,500W surge), four 120V outlets, 1,400W wall charging and an 800W solar input that accepts 12 to 78V. That runs a full-size fridge (ENERGY STAR's median of 1,500Wh a day) for about 14 hours, a CPAP with heated humidifier for about 16 hours (two nights), or a 1,500W microwave for about 35 minutes of cooking. OUPES rates the Lite at 46 minutes from empty to full and the Mega 1 at 36 minutes to 80%, and both at 3,500 cycles to 80%.

The choice is the battery port. Buy the Mega 1 Lite ($489) if a 1kWh box is all you will ever want and you would use the faster 140W USB-C ports. Buy the Mega 1 ($529) if there is any chance you will add a B2 battery later: $40 buys a path to 5,120Wh.

Fridge backup you can grow: Mega 1 with a B2 Extra Battery

OUPES sells the Mega 1 and one B2 together on Amazon as a 3,072Wh kit for $1,299, about $423 per kWh, which beats buying the two separately ($529 plus $799 for the B2). That runs a full-size fridge for about 1.7 days (3,072 x 0.85 / 1,500 Wh a day) or the 150W essentials load for about 17 hours. Output stays at 2,000W and 120V however much battery you add, and a second B2 takes it to 5,120Wh. The B2's Amazon listing gives it its own solar input, rated up to 2,100W.

240V whole-home backup: Guardian 6000 V2

The Guardian 6000 V2 is the only OUPES that makes 240V: 6,000W from one unit (3,600W at 120V), 4,608Wh, 3,600W of solar input and expansion to 41.4kWh, for $2,699 at OUPES on November 11, 2026, or about $586 per kWh. That covers a 240V well pump on a transfer switch. The catches, covered in our Guardian 6000 V2 review: you cannot link two units, OUPES lists no UL safety listing, and two bench reviews measured the original Guardian 6000 idling at about 73 to 75W with nothing plugged in. It weighs 111.8 lb, on wheels.

How the Mega 1 compares with other 1kWh power stations

Model	Capacity	AC output	Solar input	UPS switchover	Expandable	Weight	Amazon price (Nov 11, 2026)
OUPES Mega 1 Lite	1,024Wh	2,000W	800W	20ms or less	No	26.75 lb	$489
OUPES Mega 1	1,024Wh	2,000W	800W	20ms or less	Yes, to 5,120Wh	27.8 lb	$529
Anker SOLIX C1000 Gen 2	1,024Wh	2,000W	600W	Under 10ms	No	24.9 lb	$529.99
EcoFlow DELTA 3 Classic	1,024Wh	1,800W	500W	10ms	No	26.7 lb	$462
EcoFlow DELTA 3	1,024Wh	1,800W	500W	Under 10ms	Yes, to about 5kWh	27.6 lb	$579
BLUETTI Elite 100 V2	1,024Wh	1,800W	1,000W	10ms or less	No	About 25 lb	$498.99 (pre-order)

Amazon prices change daily. On these numbers the Mega 1 Lite is the cheapest 2,000W unit in the table, and the Mega 1 matches the Anker C1000 Gen 2's price while adding an expansion port, a stronger 800W solar input and the highest surge rating in the table. What you give up is UPS speed: every rival here switches in 10ms or less, against 20ms for both OUPES units, and a desktop PC can restart on a 20ms gap. If that matters, or you want the lowest price, the EcoFlow DELTA 3 Classic was $462. If you want expansion with a 10ms UPS, the EcoFlow DELTA 3 costs $50 more than the Mega 1.

Which OUPES models are sold out or discontinued?

Model	Capacity and output	Status on November 11, 2026	What to look at instead
Mega 2 and Mega 2 Pro	2,048Wh, 2,500W	Both titled sold out at OUPES ($1,499 and $1,599 list); the Pro out of stock on Amazon	Mega 1 with a B2 (3,072Wh); see our Mega 2 review for non-OUPES matches
Mega 3	3,072Wh, 3,600W	Sold out at OUPES ($2,299), with its solar and battery kits	Mega 1 with a B2, or the Guardian 6000 V2
Mega 5	5,040Wh, 4,000W	Sold out at OUPES ($3,499), with its B5 battery and its kits	Guardian 6000 V2
Guardian 6000 (original)	4,608Wh, 6,000W	Sold out at OUPES ($2,499)	Guardian 6000 V2
Exodus 600 and Exodus 600 Plus	256Wh and 512Wh, 600W	Sold out at OUPES	Exodus 350 or Exodus 700
Exodus 1200	992Wh, 1,200W	Sold out at OUPES ($549)	Mega 1 Lite
Exodus 1500	1,488Wh, 1,500W	Sold out at OUPES ($549)	Mega 1, or Mega 1 with a B2
Exodus 2400	2,232Wh, 2,400W	Sold out at OUPES ($899), as was an older 2,400W, 2,232Wh listing ($1,099)	Mega 1 with a B2

Sold out is not the same as discontinued, and OUPES has announced an end for none of these. It has replaced models before: the Guardian 6000 gave way to the V2, and the Mega 2 to the Mega 2 Pro. Our reading of what OUPES now stocks is that the Exodus 350 and 700 have taken over from the Exodus 600 models at the small end, and the Mega 1 Lite from the Exodus 1200 at 1kWh. That is our inference, not an OUPES statement. Capacities and outputs for the older Exodus models come from OUPES's June 2025 Mega vs Exodus comparison; for brand-by-brand replacements, see our discontinued power stations guide.

OUPES extra batteries: B2, B5 and G5

• B2 (2,048Wh) fits the Mega 1 (up to two), the Mega 2 and Mega 2 Pro (up to four) and the Mega 3 (up to six). It weighs 41.8 lb and was $799 on Amazon, sold by OUPES-US and in stock, on November 11, 2026, about $390 per kWh.
• B5 fits only the Mega 5, up to eight for about 45kWh in total by OUPES's figure. OUPES listed it sold out ($900 on sale, $1,400 regular).
• G5 (4,608Wh) fits only the Guardian 6000 V2, up to eight. It weighs 80 lb and was $1,400 on Amazon and $1,190 at OUPES on November 11, 2026. OUPES's older B2 and B5 packs do not fit the Guardian.
• The Exodus 350, Exodus 700 and Mega 1 Lite take no extra battery.

Our expandable power station guide compares these with EcoFlow, Anker, BLUETTI and Jackery expansion packs.

OUPES warranty, UPS speed and safety listings

Warranty: OUPES gives 5 years on its power stations, plus a free sixth year when you register the unit (OUPES's store FAQ), and its Amazon listings state 5 years. Keep the order confirmation either way; our warranty comparison sets this against other brands.

UPS: the Exodus 350 and 700 switch over in 10ms or less, for loads up to 600W and 960W. The Mega 1 and Mega 1 Lite take 20ms or less, for up to 2,000W; the Mega 3's listing and the Mega 5's manual cap pass-through at 2,200W. The Guardian 6000 V2's 20ms UPS works only while it charges from 120V, on two outlets and the RV outlet.

Temperature: every OUPES manual we read rates operation from 32°F to 104°F, so a unit kept in an unheated garage or a winter camper needs warming before use.

Safety listings: for the Mega 2 and the Guardian 6000 V2, OUPES lists only UN38.3 (a battery transport test) and an MSDS, with no UL safety listing. EcoFlow names UL 9540 for some of its units; our most reliable power station brands guide explains what those listings mean. OUPES ships US orders from warehouses in Rialto, California and Buford, Georgia, according to its store.

OUPES power station lineup: the short version

For most people the OUPES lineup comes down to three units that were in stock on November 11, 2026. The Exodus 700 ($294.49 on Amazon) for a CPAP night or a mini fridge, the Mega 1 ($529) as a 1kWh, 2,000W box that can grow to 5,120Wh, and the Guardian 6000 V2 ($2,699 at OUPES) for 240V. Everything bigger than the Mega 1 in the Mega line was sold out, so until it returns, compare the Mega 1 with a B2 against the 2kWh and 3kWh units in our best power stations under $1,000 and budget Amazon brands guides.
