What do you need to keep running?
Start with the smallest setup that covers your essentials. A charged phone and a light may be enough for you. Keeping internet equipment or a fridge running takes a different plan.
Already have a working battery? Try it with your essential devices before replacing it. If you're unsure about size, use the estimator below.
Size the need before the battery
A power station has an energy capacity, usually measured in watt-hours (Wh). Appliances use power in watts (W). Runtime depends on both, plus conversion losses and the way the appliance cycles on and off. The calculator below is a planning estimate, not a promise of runtime.
Backup power estimator
Add up your devices’ average power use in watts. Then enter how many hours you need them to run.
Example values are shown below. Replace them with your own. For average use, check the manufacturer’s energy-use information or use a plug-in power meter. A maximum rating on a label isn’t always the average.
Estimated capacity: 1,500 Wh
Includes a rough 20% allowance for conversion losses. Check actual usable capacity and start-up surge. A fridge's draw cycles; its running wattage is not its average draw.
Choose dependable lighting
Use lanterns for rooms and flashlights for moving safely. Prefer adjustable brightness and a second charging or battery option. Store at least one light where it can be reached in complete darkness.
What the estimate does and doesn't tell you
Check the actual wattage label or measure your devices. A refrigerator compressor can draw more power while starting, even if its average use is modest. A station must support both the running load and any starting surge. Battery output, temperature, battery age and charging strategy also affect real results.
For long outages: a battery only stores finite energy. Plan how to recharge or reduce the loads. Never run a fuel-powered generator inside a home, garage or other enclosed space; carbon monoxide can be deadly.
How to compare options
Once you know your target capacity, compare usable Wh, continuous and surge output, ports, charging time, warranty and your plan for recharging. A small power bank may be enough for phones. A refrigerator or medical device calls for a more careful calculation.
Protect essential medical equipment
For life-sustaining equipment, contact its manufacturer and your care team about suitable backup power, safe runtime and when to relocate. Do not rely on a general-purpose estimate alone.
These are researched options to compare, not a claim that one product is best for every household. Choose by the devices you need, the runtime you want and how you'll recharge.

01 / PHONES & USB DEVICES
Belkin BoostCharge 20K (BPB012)
20,000mAh · 15W shared USB output · 2-year warranty
Why consider it: Consider this if your priority is charging phones and small USB devices. You may already own a power bank that does the job, so check it before buying another.
The trade-off: It doesn't have household AC outlets. Its 15W output is shared across the ports, so it isn't a laptop power solution or the fastest way to charge several phones.
Bring the right cables. The battery's mAh rating isn't the amount delivered to your phone, and it doesn't tell you an exact number of charges.
Why consider it: Consider this UPS for automatic backup during brief outages. It has five battery-backed outlets and two surge-only outlets. Keep the modem and router on the battery-backed ones.
The trade-off: 600VA is an output rating, not 600Wh of stored energy. Check APC's runtime chart for your combined load instead of assuming it'll last all day.
Your provider's network also needs to stay online. Include any fibre terminal or other equipment your connection needs, and test the setup before an outage.
286Wh capacity · 600W rated AC output · 5-year Canadian warranty*
Why consider it: Consider this when you want USB charging and household outlets in one compact battery. It bridges the gap between a phone power bank and a larger station.
The trade-off: 286Wh is a modest energy supply. A 600W output rating doesn't mean it can deliver 600W for an hour. Use the calculator for your total load and planning period.
Choose RIVER 3 Plus, not the different RIVER 3 model. Confirm whether the offer includes only the station or an extra battery or solar panel.
1,024Wh capacity · 2,000W continuous output · About 11.3kg
Why consider it: Consider this for more electronics or a compatible appliance after checking its running power, starting surge and energy use. It offers substantially more stored energy than the RIVER 3 Plus.
The trade-off: Its battery capacity isn't expandable. It isn't whole-home backup, and a fridge runtime can't be promised without knowing that fridge's consumption and conditions.
Check the exact Canadian warranty with the seller. Anker advertises a five-year SOLIX warranty, but we couldn't confirm the model-specific terms through its linked warranty chart. Direct shipping excludes the three territories.
For illustration, suppose your devices average 20W. Using the estimator's rough 80% usable-energy assumption, 286Wh works out to about 11 hours, and 1,024Wh to about 41 hours. These are calculations, not tested runtimes. Inverter overhead, temperature, battery age and changing loads can shorten them, especially with small loads.
For a full day at 20W, the same estimate calls for 600Wh. That's why a small station can have enough output power but still fall short on runtime. A UPS needs its own manufacturer's runtime chart, not this capacity comparison.
Before you buy
Check the total cost. Compare the exact station, required cables, charger, delivery and taxes. Solar panels and extra batteries aren't automatically included.
Have a recharge plan. A battery doesn't create energy. For several days, work out when and how you can recharge it. Solar charging depends on the panel, weather and placement.
Read the temperature limits. Charging and discharge limits can differ. For example, Anker lists 0–40°C for charging the C1000 Gen 2. Don't assume an unheated garage is a suitable winter charging spot.
Check compatibility before counting on it. These comparisons cover plug-in devices. They don't establish compatibility with a furnace, well pump, home electrical panel or essential medical equipment.
You don't need to buy all four. Choose the setup that covers your essentials, test it, and keep it charged according to the manufacturer's instructions.
