Portable Power Bank vs Portable Power Station
A portable power bank charges phones and small gadgets through USB. A portable power station is a much bigger lithium battery with AC sockets that can run fans, a router, a TV or even a fridge. If you want load shedding backup at home, you need a power station; for your pocket or travel bag, a power bank. Here is how they compare.

The short answer
- Power bank: about 10,000 to 30,000 mAh (roughly 37 to 110 Wh), USB output only, fits in a pocket or bag. For phones, earbuds, small fans and sometimes a laptop.
- Power station: about 250 Wh to 2,000 Wh or more, with 230V AC sockets, USB and car ports. For a router, laptop, lights, fans, a TV or a fridge during outages.
A mid-size power station such as the EcoFlow DELTA 3 (1,024 Wh) holds about as much energy as ten or more large power banks.
Capacity: mAh vs Wh
Power banks are rated in mAh at the cell voltage, usually 3.6 or 3.7V, which makes the number look big. To compare, convert to Wh: mAh x 3.7 / 1000. A 20,000 mAh power bank is about 74 Wh.
Power stations are rated directly in Wh. The EcoFlow RIVER 3 is 245 Wh, the Jackery Explorer 500 is 518 Wh, and the DELTA 3 Max is 2,048 Wh. Our kWh guide (Battery kWh vs Ah: Lithium Battery Capacity Explained) explains these units.
Output: USB vs AC sockets
A power bank gives 5 to 20V DC through USB-A and USB-C. Some large ones support laptop charging over USB-C, but they cannot run anything with a normal plug.
A power station has a built-in inverter with AC output, for example 300W on the RIVER 2 and RIVER 3, 1,800W on the DELTA 3 and Anker SOLIX C1000, and 2,400W on the DELTA 3 Max. That is what lets it run fans, a fridge or a desktop computer.
What each one runs during load shedding
- Power bank (20,000 mAh): a phone two to four times, or a 5V router for several hours with the right cable.
- Small power station (about 250 Wh): router and laptop for about 3 to 4 hours, or LED lights all evening.
- 1 kWh power station: a ceiling fan for about 11 hours, or fan, lights and router for about 5 to 6 hours.
- 2 kWh power station: a fridge for most of a day.

Charging, solar and travel
Power banks charge from a phone charger in a few hours. Power stations charge from a wall socket, car socket or solar panels; many reach full in one to two hours on AC. See solar generator for home (Solar Generator for Home in Pakistan: Sizes, Uses and Best Picks).
For flights, power banks are normally allowed in hand baggage within watt-hour limits. Power stations are far above those limits and are usually not allowed on passenger planes. Check your airline's rules.
Battery type and life
Most phone power banks use lithium polymer or 18650 NMC cells, rated for a few hundred full cycles. That is fine for a device you charge a few times a week.
Power stations vary. The EcoFlow RIVER and DELTA ranges, Anker SOLIX C1000 and Itel ITEL-63 use LiFePO4 cells rated 3,000 to 6,000 cycles, which suits daily load shedding. The Jackery Explorer models in our catalogue use NMC cells rated around 500 cycles, which suits occasional use and travel better. See LiFePO4 vs lithium-ion (LiFePO4 vs Lithium-ion Battery: Differences Explained).
Which should you buy?
- Phone and earbuds on the move: a power bank.
- Wi-Fi and laptop for freelancing during outages: a small power station such as the EcoFlow RIVER 3 or RIVER 2.
- Fans, lights and TV in one room: a 1 kWh unit such as the EcoFlow DELTA 3 or Itel Power Tank ITEL-63.
- Fridge and long outages: a 2 kWh unit such as the DELTA 3 Max.
