Quick answer: before Black Friday (November 27, 2026), work out the watt-hours you actually need, then look for a LiFePO4 battery with a stated cycle rating, continuous output above your biggest appliance, fast AC charging (about an hour on current 1 kWh models), a solar input that matches any bundled panel, and a warranty from an authorized seller. Judge a deal by price per watt-hour and the product’s price history, not by the size of the “was” price.
How we wrote this: specs and warranty terms come from manufacturers’ official pages, checked in September 2026. Runtimes are our calculated estimates, with the math shown. We haven’t tested these units hands-on, and we don’t quote prices because they change daily. See How We Test.
Black Friday 2026: what to do and when
| When | What to do |
|---|---|
| Now through early November | Do the sizing math below, shortlist 2–3 models, and write down each one’s normal price on the maker’s site and at your usual retailer. |
| Early to mid November | Brands often start holiday promotions before Black Friday. Compare every early offer with your notes. |
| Black Friday, November 27 | Buy only if the price beats what you wrote down and the unit passes the checklist at the end of this guide. |
| Cyber Monday, November 30 | Last big round of deals. Bundles and accessory offers often change, so compare again. |
| The day it arrives | Charge it fully, try every outlet you’ll use, register the warranty, and keep the box and receipt until the return window closes. |
Why bother now? Because the shoppers who get burned on Black Friday are usually the ones who decide in five minutes. Twenty minutes of homework today tells you which deal is real, and which “deal” is the wrong size at a normal price. If you’re still unsure you need one at all, start with is a portable power station worth it?
Step 1: Size it before you shop
The most expensive Black Friday mistake is a great price on the wrong size. Use this formula:
Capacity needed (Wh) = hours × average watts ÷ 0.85
The 0.85 accounts for the roughly 15% of a battery’s rated capacity you lose to conversion and reserve. For devices plugged into the AC outlets, add about 10 W for the inverter.
Worked example: an overnight outage
- List the devices. An average refrigerator (about 1.5 kWh a day, or 62.5 W on average), a Wi-Fi router (about 10 W) and an LED lamp (about 10 W): 82.5 W.
- Add the inverter. 82.5 + 10 = 92.5 W.
- Multiply by the hours. A 12-hour outage: 12 × 92.5 = 1,110 Wh.
- Divide by 0.85. 1,110 ÷ 0.85 ≈ 1,306 Wh.
So the hot 1 kWh doorbuster (1,024 Wh) would run this setup for only about 9.4 hours, not the whole night. A 2 kWh unit (2,048 Wh) runs it for about 18.8 hours, and an expandable 1 kWh unit lets you add a battery later. That’s the kind of answer you want before the sale, not after. For your own devices, use our full sizing guide.
| Main job | Typical load | Size to shop for | Estimated runtime |
|---|---|---|---|
| Weekend camping: phones, lantern, laptop over USB | About 120 Wh per day | About 300 Wh | About 2 days on a 286 Wh unit |
| Home office through a short outage: router + laptop on AC | About 70 W | 300 Wh–1 kWh | About 3.5 h on 286 Wh; about 12 h on 1,024 Wh |
| Refrigerator only, overnight | About 72.5 W | About 1 kWh | About 12 h on 1,024 Wh |
| Fridge + Wi-Fi + lamp + phones | About 95 W | About 2 kWh | About 18 h on 2,048 Wh |
| Multi-day storm outage | About 95 W around the clock | 2 kWh or more, plus solar or an extra battery | About 1.8 days with 440 W of panels (see scenario 1) |

Step 2: The specs that matter (and the red flags)
| Spec | What to look for | Red flag |
|---|---|---|
| Capacity (Wh) | What your math says, rounded up | Choosing the size because of the discount |
Continuous AC output  | Higher than the running watts of your biggest device; surge (peak) watts for fridge compressors and pumps | Only the peak figure advertised in large print |
| Battery chemistry | LiFePO4 (LFP) with a cycle rating to 80% capacity; the EcoFlow DELTA 3 Plus, for example, is rated for 4,000 cycles | No chemistry or cycle count on the listing; older lithium-ion (NMC) stock on clearance |
| AC charging | About an hour for a full charge on current 1 kWh models (the DELTA 3 Plus is rated at 56 minutes with 1,500 W input) | Several hours with no fast-charge mode |
| Solar input | Wattage and voltage range that fit your panels (the DELTA 3 Plus has two inputs, 11–60 V and 500 W each) | A bundled panel that falls outside the input range |
| UPS switchover | 20 ms or faster; under 10 ms is better for desktop computers | “Pass-through charging” with no switchover time stated |
| Outlets | Enough AC outlets to run everything at once; USB-C of 100 W or more for laptops | A single AC outlet on a unit sold for home backup |
| Expandability | An add-on battery option if your needs could grow | Paying extra for expansion you’ll never use |
| Weight | Something you can move; current 1 kWh models weigh roughly 24–28 lb | A “portable” unit you can’t lift into your car |
| Warranty | Current flagship models often carry 5 years, sometimes as 3 years plus 2 with registration | 1–2 years, or no warranty terms on the listing |
If a deep discount is on an older lithium-ion model, remember that LiFePO4 batteries are rated for several times more charge cycles. A cheaper unit that wears out years sooner isn’t cheaper. Our LiFePO4 vs lithium-ion guide explains the difference.
Step 3: Tell a real deal from a fake one
The Federal Trade Commission’s Guides Against Deceptive Pricing say a “former price” is a fair basis for a discount claim only if the item was actually offered at that price, regularly, for a reasonably substantial period. A price that was inflated briefly so the sale looks bigger is what the guides call a fictitious former price. Not every retailer follows the spirit of that rule, so check for yourself:
- Check the price history. Use the notes you took in October or a price-tracking tool. If the “was” price only appeared a few weeks before the sale, ignore the percentage.
- Compare price per watt-hour. Divide the price by the Wh. If a 2,048 Wh unit costs 1.6 times as much as a 1,024 Wh unit, you pay 20% less per watt-hour (1.6 ÷ 2 = 0.8). That’s only a win if you’ll use the extra capacity.
- Compare sellers. Check the same model on the maker’s own store and on two big retailers on the same day.
- Check the model number. A big discount may be on last year’s version. Search the exact model name on the maker’s site.
| Signal | Probably a real deal | Probably not |
|---|---|---|
| “Was” price | Seen for months | Appeared just before the sale |
| Maker’s own store | Same price or higher | Maker sells it for less |
| Model generation | Current model | Previous model near the current model’s price |
| Seller | The brand or an authorized retailer | Unknown marketplace seller with a huge discount |
| Bundle extras | Things you’d buy anyway | Accessories you don’t need, padding the “value” |
Solar bundles: when they’re worth it
Bundles are popular on Black Friday. They’re a good buy when you’ll really use solar (outages longer than a day, camping, van trips) and when the panel fits the station. Before you add one to your cart:
- Check compatibility. The panel’s voltage must fall inside the station’s solar input range, and the connector must match (or an adapter must be included).
- Estimate real output. Panels deliver about 75% of their rating in real use, and most of the U.S. gets 3–6 peak sun hours. A 220 W panel on a 4-sun-hour day: 220 × 0.75 × 4 ≈ 660 Wh, about three-quarters of a 1,024 Wh station’s usable capacity.
- Price it separately. Add up the station and panel bought on their own. The bundle should cost less, not just look like more.
To size panels for your station, see how many solar panels you need.
Where you buy matters: warranty and returns
- Buy from the brand or an authorized seller. EcoFlow’s U.S. warranty covers products bought from EcoFlow or an authorized seller, in the original packaging, and starts on the delivery date. Jackery states that products bought from unauthorized dealers aren’t covered by its warranty, and it publishes a list of authorized sellers. On Amazon and other marketplaces, check the “sold by” name.
- Read the fine print on charging. Jackery’s U.S. policy says battery-cell coverage requires you to fully charge the unit within seven days of purchase and at least every six months after that. Don’t leave a Black Friday unit sealed in its box until the next storm.
- Know who’s covered. Jackery’s warranty is limited to the original purchaser. A “like new” unit resold by a stranger may have no coverage at all.
- Consider official refurbished units. Some brands run their own refurbished stores. They can be good value if the listing states a clear warranty.
- Check the return window. For the 2025 season, Amazon let most items bought from November 1 to December 31 be returned until January 31. Check whether your retailer offers the same in 2026, and test the unit early.

Three real-world scenarios
1. A Gulf Coast homeowner preparing for next hurricane season
Goal: keep the fridge, Wi-Fi, a lamp and phones going (about 95 W) through a multi-day outage. A 2,048 Wh unit alone lasts about 18 hours (2,048 × 0.85 ÷ 95). Add two 220 W panels: 440 × 0.75 × 4 sun hours ≈ 1,320 Wh a day, against a daily need of 95 × 24 = 2,280 Wh. The battery then drains by only about 960 Wh a day, so it lasts about 1.8 days, and longer on sunny days or if you unplug the fridge at night. What to buy: a 2 kWh unit with at least 440 W of solar input, or an expandable model. Black Friday is a smart time for this buyer: it’s months before the season starts. Compare options in our best power stations for home backup.
2. A weekend camper
Daily use: two phone charges (about 15 Wh each, estimated), an LED lantern at 5 W for 5 hours (25 Wh) and one laptop charge (about 65 Wh), roughly 120 Wh a day over USB. A 286 Wh unit gives about 243 Wh of usable energy, just enough for a two-day weekend with nothing to spare. What to buy: a light 300 Wh-class unit with strong USB-C, plus car charging or a small panel for margin. A 2 kWh “deal” would mean carrying 30 to 40 extra pounds you don’t need (current 2 kWh models weigh about 42–49 lb, versus roughly 8–10 lb for 300 Wh units). See our best small power stations for camping.
3. A remote worker in a low-outage state
In 2024, Arizona customers averaged under two hours without power, according to the U.S. Energy Information Administration, and routine U.S. outages run about two hours a year. A router and laptop on AC draw about 70 W, so a two-hour outage needs about 165 Wh (2 × 70 ÷ 0.85). What to buy: a small unit of about 300 Wh (about 3.5 hours of runtime) is plenty. Skip the big home-backup bundles, no matter how large the discount.
Common Black Friday mistakes
- Buying the biggest discount instead of the right size. Too small leaves you in the dark; too big means weight and money you’ll never use.
- Trusting the “was” price. Compare with price history and the maker’s own store.
- Buying a bundle without checking the solar input. A panel outside the voltage range won’t charge the station properly.
- Buying from an unauthorized seller. You may save a little and lose the warranty.
- Leaving it in the box. Charge it, try it with your real devices while you can still return it, and top it up every few months.

- Any bundled panel fits the solar input range.
- The UPS switchover time is listed, if I need UPS mode.
- There are enough AC outlets and USB-C ports for my gear.
- The seller is the brand or an authorized retailer.
- I know the warranty length and whether I must register or charge the unit to keep it.
- The price beats the history I noted, and I know the return deadline.
Frequently asked questions
When do Black Friday power station deals start?
Brands often launch holiday promotions in early or mid November, and some run fall sales even earlier. In 2026, Black Friday is November 27 and Cyber Monday is November 30. Note your target prices now so you recognize a good offer whenever it appears.
Should I buy now or wait for Black Friday?
If you have no backup power and live somewhere prone to storms, being unprepared costs more than missing a discount. Otherwise, waiting is reasonable, as long as you track the price and don’t let the sale talk you into the wrong size.
Does buying on Amazon void the warranty?
Not if the seller is the brand’s official store or an authorized retailer. Warranty policies such as Jackery’s exclude unauthorized dealers, so compare the “sold by” name with the brand’s list of authorized sellers before you check out.
Is a refurbished power station a good buy?
It can be, if it comes from the brand’s own refurbished program and the listing states the warranty length. Avoid used units from strangers: warranties are often limited to the original purchaser.
Are solar generator bundles worth it?
Yes, if you’ll use solar for long outages or camping, the panel fits the station’s input range, and the bundle costs less than buying both separately. If you only need backup for short outages, buy the station alone and add panels later.
What size power station do I need for a refrigerator?
About 1 kWh runs an average refrigerator for roughly 12 hours, an overnight outage. For the fridge plus Wi-Fi, a lamp and phones through a full day, look at 2 kWh or more.
The bottom line
The best Black Friday power station deal is the right size, with a LiFePO4 battery and a real warranty, bought from an authorized seller at a price that beats its own history. Do the math and write down your target prices now. On November 27, you’ll only need a few minutes to decide.
