Portable Power Stations (2026): Capacity, Runtime & LiFePO4

A portable power station is a large rechargeable battery with built-in sockets: AC outlets, USB-C and USB-A ports, and often a car socket. It can run a laptop, Wi-Fi router, fan, lights or a CPAP machine during power cuts, on road trips or at a campsite, and it recharges from the wall, a car or solar panels. Unlike a petrol generator, it is silent and fume-free. But it is also expensive per unit of energy, so the key is buying the right size for what you actually need to run.

Quick answer

• Phones, laptop and Wi-Fi during short outages, or weekend trips: roughly 250–500 Wh.
• Fans, lights, router and laptop for an evening, or camping with a small cooler: roughly 500–1,000 Wh.
• Longer outages or larger appliances: 1,000 Wh and above, but first compare the cost with a home inverter and battery.
• Prefer LiFePO4 batteries and a pure sine wave inverter.

Watt-hours vs watts: the two numbers that matter

Capacity in watt-hours (Wh) is how much energy the battery stores; it decides how long things run. Output in watts (W) is how much power it can deliver at once; it decides what you can run. A station with 500 Wh capacity and 300 W output can run a 60 W fan for hours, but cannot run a 1,500 W kettle at all. Many stations also list a higher "surge" rating for the brief spike when motors start.

How to estimate runtime

Use this rule of thumb: runtime (hours) ≈ capacity (Wh) × 0.85 ÷ total load (W). The 0.85 accounts for losses when converting battery power to AC. Examples for a 500 Wh station:

• Wi-Fi router (about 10 W): roughly 40 hours.
• Laptop charging (about 45–65 W): roughly 6–9 hours.
• BLDC ceiling fan (about 30 W) plus router (10 W): roughly 10 hours.
• Conventional ceiling fan (about 75 W) plus an LED bulb (9 W): roughly 5 hours.

Check the actual wattage on your devices' labels or adapters, and add up everything you want to run at the same time.

Battery chemistry: LiFePO4 vs NMC

LiFePO4 (lithium iron phosphate) batteries are heavier for the same capacity but last far more charge cycles (often rated at 2,000–3,000+ cycles to 80% capacity), handle heat better and are considered safer. NMC batteries are lighter and were common in older models, but are rated for fewer cycles. For Indian heat and frequent use as power backup, LiFePO4 is the better long-term choice.

Other features to compare

• Pure sine wave AC output: safe for laptops, fans, medical devices and motors.
• Socket types: check that the AC sockets accept Indian plugs, or that suitable adapters are included.
• USB-C Power Delivery: 60–100 W USB-C ports charge laptops directly and more efficiently than using the AC socket.
• Charging speed: some stations recharge from the wall in one to two hours; others take six or more.
• Solar input: maximum solar watts and voltage range, with a built-in MPPT controller for efficient solar charging.
• UPS / EPS mode: lets the station act as a backup supply that switches over during a power cut. Check the switchover time if you use it for a desktop PC or router.
• Weight and handle: 500 Wh LiFePO4 units often weigh 6–8 kg; larger ones are much heavier.

Solar generators

A "solar generator" is a power station sold with folding solar panels. Real-world solar output is often 60–80% of the panel's rated watts, and less on cloudy monsoon days, so a 100 W panel might add about 300–500 Wh on a sunny day. That is enough to top up phones, lights and a fan for camping, but not to run heavy appliances daily.

When a home inverter is the better buy

If you want backup at home only, for fans and lights during regular power cuts, a conventional home inverter with a tubular battery usually gives much more backup per rupee than a portable power station. Portable stations make sense when you need portability (travel, camping, shoots), silent and maintenance-free operation, solar charging away from home, or backup in a rented flat where installing an inverter is not possible.

Checking prices

When we searched "portable power station" on PriceQ for this update, the results were mostly USB charging hubs, power banks and tyre inflators rather than true power stations. That is a useful warning: search by specific capacity and battery type, and check that the listing shows Wh capacity, AC output wattage and battery chemistry. Compare portable power station prices with PriceQ.

A note on "discounts": many listings in this category show an MRP far above the price the product actually sells for, so a "60% off" badge often means very little. Judge a deal by the selling price over time, not by the gap to MRP. PriceQ's Price History button on each product shows how the price has moved since we started tracking it.

Buying checklist

• Capacity (Wh) sized from your devices' wattage and the hours you need.
• Continuous AC output (W) above the total load you will run at once.
• LiFePO4 battery and pure sine wave inverter.
• Indian-compatible AC sockets and USB-C PD ports.
• Solar input with MPPT if you will charge from panels.
• UPS mode if you want automatic backup.
• Warranty (ideally 2+ years) and service support in India.

Frequently asked questions

Can a power station run an AC or refrigerator?

A refrigerator, briefly, on larger units with enough surge capacity. Air conditioners need very large, expensive systems and are not practical on typical portable stations.

Can I charge it from my car?

Yes, most include a car charging cable, though car charging is slow.

How should I store it?

Keep it at around 50–80% charge in a cool place, and top it up every couple of months.

Bottom line

Size a power station from the devices you need to run and for how long, prefer LiFePO4 and pure sine wave output, and compare the cost with a home inverter if you only need home backup. Read listings carefully, since search results in this category often mix in unrelated products. See today's power station prices on PriceQ.

How we put this guide together: we compared current listings and prices using PriceQ's own price search, and combined them with the specifications that matter for Indian homes. We have not lab-tested these products. PriceQ may earn a commission when you buy through store links, at no extra cost to you; this never affects which products we mention.
