When the power goes out, stay running.
Assumbl helps you choose a complete portable power setup — station, panels, and the hardware that ties it to your house — sized for what you actually need to keep on.
Free to use. Currently in beta — Portable Power is one of our two first categories.How it works
Sizing a power station means reading watt-hours, surge watts, and recharge curves across a dozen tabs. We built Assumbl to get you there in minutes.
Step 1: Tell us what you need to keep running
A 5-7 minute questionnaire covers what you want powered, for how long, where the setup lives, and your budget. No technical knowledge needed.
No signup required to startStep 2: We match the pieces
Our system compares your answers against measured specifications, so the station, the panels, and the expansion battery you get are actually rated for each other.
Step 3: Review your setup
You get a complete recommendation with plain-English explanations of why each piece fits, plus links to buy from established retailers.
What a complete setup includes
Most setups combine a few of these. Which ones you need depends on whether you are covering an outage, a worksite, or a camper — and on what you want running when the power is out.
Power station
The battery and inverter in one box. Two numbers decide almost everything: how much energy it stores, and how much it can deliver at once.
Solar panels
What turns a battery into a supply that refills itself. Panel output has to match the station's charging limit, or you pay for watts it cannot take.
Expansion batteries
Extra capacity that plugs into the station you already own. Almost never cross-brand, which is why the pairing has to be settled before you buy the station.
Home integration
Transfer switches and inlet boxes, for running circuits rather than extension cords. This is the step between a camping battery and a house backup.
Adapters and cables
The unglamorous part that decides whether anything connects at all: charging cables, car adapters, the right plug for the right port.
Transport and protection
Cases, covers, and carts. It matters more than it sounds once a unit passes fifty pounds and has to leave the garage.
What we check before recommending
Most disappointment with a portable power station comes from one of these four, and all four are readable from the specifications before you spend anything.
Capacity against your actual load
Watt-hours only mean something next to what you want to run. A fridge overnight and a CPAP overnight are not the same problem, and neither is a jobsite saw.
Continuous output, and the surge
Anything with a motor draws several times its rated power for a second when it starts. A station sized on continuous watts alone will trip the moment the compressor kicks in.
How it refills
Wall, car, or solar — and how fast for each. A multi-day outage is won or lost on the recharge path, not on the size of the battery.
Chemistry and cycle life
Two units at the same price can differ by thousands of charge cycles. If the unit sits on standby for years and gets used twice a winter, that difference is the whole purchase.
Where we're headed
Portable power is one of the two systems we cover today. More complex home systems are on the roadmap.
For power brands and retailers
Assumbl sends you shoppers who already know what they need. Here is what that means in practice.
High-intent traffic
Visitors state what they need to keep running, for how long, and on what budget before they see a single product. The clicks you receive come from people who have already invested time in their decision.
Compared on specifications, not copy
We sort on usable capacity, continuous and peak output, recharge behaviour, and cell chemistry. A product that is genuinely better on those numbers wins on our pages.
Transparent tracking
We work through standard affiliate networks, with tracking and attribution you can verify on your side.
Affiliate disclosure
Assumbl is free for you to use. When you buy a product through links on our site, we may earn a commission from the retailer or manufacturer, at no extra cost to you.
