Ultimate Off-Grid Generator is a set of downloadable build plans, not a finished generator, and it costs $49.00 as a single payment. The seller, personalenergysecrets.com, states a 60-day money-back guarantee. The $69 and $49 figures are the seller’s own, and this site has not verified them. The seller says the plans include a manual, schematics, a parts list and step-by-step guides, and that you can \”easily power up an entire home with under $210 in total costs.\” Power claims are easier to judge in household terms: a 200-watt refrigerator running for 10 hours uses about 2,000 watt-hours, which you can price at your own electricity rate. The physics is basic, as the Open University’s free OpenLearn guide explains: a generator converts mechanical energy into electrical energy. This page covers what you receive, what the build takes, the refund steps, the safety points and cheaper alternatives.

Is Ultimate Off-Grid Generator a finished generator or a set of plans?
It is a set of plans. The sales page says the blueprints are \”available in electronic format, for instant download,\” so what arrives is files you read and follow. You build the unit yourself. The sales page describes digital files, not a device.
The seller pitches it to people who want lower electric bills, backup power in an outage, or power for a cabin or camper. If you want to compare a similar blueprint offer, read the tesla’s off-grid generator blueprints review on this site. Another off-grid generator offer is covered in the lost generator reviews.
What does the seller say it does, and how is it meant to work?
The seller describes the finished unit as light, quiet and low-maintenance. Its claims include:
- It can be installed \”in your basement, or in your back yard.\”
- Apart from \”a simple maintenance check every few months,\” the seller calls it \”Set And Forget.\”
- \”There are no emissions, no fumes, no radiations,\” the sales copy says.
- A device that \”can last for tens of years without any intervention.\”
- Savings that could \”slash your bill by 50%… 80%… or even more.\”
Ask the seller to name it before you order. That answer is the simplest check on the \”tens of years\” claim.
What do you actually get, and how long does the build take?
These are the seller’s own figures. Check them against the parts list before you rely on them.
| Item | Seller’s figure |
|---|---|
| Reading the blueprints | \”a little over 60 minutes\” |
| Building the unit | Under 4 hours for a slower builder |
| Parts, small-scale build | \”about $73 worth of parts\” from an electronics store |
| Parts, whole-home scale | \”under $210 in total costs\” |
| Hiring someone to build it | \”pay someone $50\” to read the blueprints and build it |
| Total cost of one buyer’s build | \”a little under $108,\” in a testimonial on the sales page |
Ask the seller for the full parts list before you order, and confirm which tools the build needs. Those two things decide what you actually spend.
Can you make your own electricity at home?
Yes, a home system can generate or store power. The question is which kind and how much. Duracell’s guide says it \”is possible to generate your own electricity at home and has become far easier with the rise of home battery storage systems.\” Duracell sells home batteries, so read its guide as a seller’s view.
The Open University’s free guide describes a different, simple demonstration generator made from basic materials. This site has not tested the seller’s design. The OpenLearn guide defines the principle: \”A generator is simply a device that converts mechanical energy (itself derived from coal, oil, natural gas, wind, water, nuclear reactions or other sources) into electrical energy.\” The EIA’s explainer on how electricity is generated gives a plain example: \”Hydroelectric turbines use the force of moving water to spin turbine blades to power a generator.\”
So every generator needs an energy source to turn. When a seller says a device runs for decades with no input, ask it to name that source.
How much power do you need, and how long will it run?
Start with watts and watt-hours. Good Housekeeping says \”Small generators have capacities around 250 watts, while larger ones offer 3,000 watts or more.\” Its guide adds that \”gas generators work better for larger demands, especially 10,000 watts or more.\” A 10,000-watt unit sits in the range it assigns to gas generators for big loads. To see what it would run, add up the watts of the appliances you want at the same time, using each appliance’s label, and compare that total with the rating. For whole-house sizing, the solar generator sizing guide on this site walks through the math.
Runtime is watt-hours divided by watts. Rhino USA’s guide says \”Battery capacity is measured in watt-hours (Wh), indicating how much energy the generator can store.\” Wirecutter’s guide uses the same idea, saying a unit with enough capacity \”allows you to run a 300-watt appliance for one hour.\” So 2,000 watt-hours runs a 200-watt refrigerator for about 10 hours. Good Housekeeping also warns: \”Overloading a generator can damage it and connected electronics.\”
To price the running cost, multiply watts by hours and divide by 1,000 to get kilowatt-hours. Then multiply by your rate per kilowatt-hour, which is on your bill. A 200-watt refrigerator running for one hour uses 0.2 kilowatt-hours.
The sales copy claims you can \”easily power up an entire home with under $210 in total costs.\” The Ultimate Off-Grid Generator sales page does not show a wattage or watt-hour rating for the finished unit. Ask the seller for both numbers before you order, and check them against the appliances you plan to run.

Refunds, returns and cancelling: the exact terms and steps
The seller’s refunds page calls it \”a 100% money-back return policy.\” Here are the steps, in order:
- Within the window: the refunds page says you can ask for a refund \”at any time during the first 60 days after purchase.\” Count from the purchase date on your receipt.
- Send a short email to [email protected] and ask for a full refund. The sales page calls this a \”No Questions Asked Money Back Guarantee\” and promises \”an immediate refund.\”
- Allow time for the money to return: the refunds page says, \”Please allow 3 to 5 business days for the refund to be posted to your account.\”
- Explaining why you are returning it is \”totally optional,\” according to the refunds page.
- For order questions, call BuyGoods customer support at (302) 200-3480. The contact page says, \”We’ll get back to you within 48 hours or less,\” for email to product support.
The sales copy describes one payment, so the refund is the way out if you change your mind.
Side effects, safety and who should skip it
This is a build plan, not something you take or apply, so a usual side-effect list does not fit. The risks sit in the build and the finished unit.
| Risk | What the source says | Source |
|---|---|---|
| Overloading the unit | \”Overloading a generator can damage it and connected electronics.\” | Good Housekeeping |
| Fumes from gas generators | Gas generators \”must be used outdoors to avoid harmful fumes\” | Good Housekeeping |
| Building skill | Today’s Homeowner says living off-grid in general \”requires technical knowledge and lifestyle adjustments\”; this is not about this product’s build | Today’s Homeowner guide |
| No emissions or fumes | The seller’s claim: \”There are no emissions, no fumes, no radiations\” | Sales copy |
If you would rather not do technical building work, this is the option to skip. The seller itself suggests you \”pay someone $50\” to build it. If you need backup that must work the first time, compare a finished, rated unit first.
Is Ultimate Off-Grid Generator legit or a scam?
Whether it is legit depends on checks you can make before you pay. Start with these:
- The seller: the sales and refund pages sit on personalenergysecrets.com, with product support at [email protected].
- Order handling: the contact page routes order support to BuyGoods customer support at (302) 200-3480, so check the merchant name on your receipt.
- Refund terms: 60 days, email request, 3 to 5 business days to post, as set out above.
- Disclaimer: the seller’s disclaimer says the content is \”strictly for informational purposes only\” and is provided \”AS IS.\” That is the seller’s own limit on what it promises.
- Payment route: keep your receipt. If the refund does not post within 3 to 5 business days, contact your card or payment provider with it.
Outside coverage of this product is limited. One review page on sourdough.com gives two different ratings for the same product, \”4.9-star rating from 12,785\” in one place and \”4.7-star rating from 6,643\” in another. Check any rating you read against the seller’s own refund terms.
How does it compare with the alternatives, including doing nothing?
Here are the options a buyer usually weighs against a DIY plan. Prices are the ones shown on each source’s page.
| Option | What it is | Cost as shown |
|---|---|---|
| Ultimate Off-Grid Generator | Build plans you assemble yourself | $49.00 single payment; parts about $73 for a small build (seller’s figures) |
| EcoFlow River 2 Pro | Wirecutter’s top pick among portable power stations | $349 from Amazon; $369 from Walmart |
| Jackery Explorer 300 | Wirecutter’s pick for short-term use | $289 from Amazon |
| EcoFlow Delta 2 Max | Wirecutter’s upgrade pick for maximum battery life | $1,029 from Amazon |
| Standby gas generator | Good Housekeeping says a standby gas generator \”is reliable and easier to install\” | Get an installer quote; prices change |
| Doing nothing | Keep your grid supply and buy no equipment | No equipment cost; you rely on the grid during outages |
Wirecutter’s guide sets its criteria this way: \”Each model must have a pure sine-wave inverter,\” \”Each model needs a max output rating of 200 W or more,\” and \”Each model must weigh 50 pounds or less.\” Its top pick is the EcoFlow River 2 Pro. Good Housekeeping’s view is that \”For lower power needs under 3,000 watts, solar generators are ideal, while gas generators work better for larger demands, especially 10,000 watts or more.\”
For a ready-made unit, the Wirecutter portable power station guide and the Good Housekeeping solar generator roundup are the independent places to start. If you want a closer look at one related unit, see the Generac GB2000 power station reviews on this site.
Before you order
- Confirm the price and any recurring charge at checkout, and keep the receipt.
- Note your purchase date. The 60-day window counts from it.
- Ask the seller for the full parts list, the tools the build needs, the energy source, and the rated wattage and watt-hours.
- Ask whether the build connects to your home wiring, and check your local rules first.
- Compare the power-station prices above before you decide.
Short answers to the other questions
Can you legally generate your own electricity?
Duracell, a home battery seller whose guide refers to the UK National Grid, says \”You do not have to use the National Grid to power up your home.\” It also describes \”a mixed system where you can use the grid for backup\” as one choice. Rules differ by place, so ask your local building office and your utility before you connect anything to your home.
What is the cheapest way to make your own electricity?
Duracell says \”Solar panels are now considered the cheapest way of generating energy, with wind power coming in a close second.\” The seller claims the unit \”costs less than $200 to build.\” Compare both with the figures in the price section.
Are there other options for home backup?
