Power bank buying guide: capacity, charging speed and flights
Three things decide which power bank to buy: how many charges you need, how fast it should charge your phone or laptop, and whether you'll fly with it.
1. Real capacity is less than the mAh on the box
The mAh figure is measured at the battery cells' voltage, usually 3.7V, and some energy is lost raising that to USB voltage. UGREEN says a 10,000mAh power bank usually delivers about 6,000 to 7,000mAh to your phone. That's roughly 1.4 charges of a 4,500mAh phone, or about two of a 3,000mAh one (UGREEN).
A 20,000mAh bank gives about twice as many charges, but it's heavier to carry. Some makers print the real figure too: UGREEN rates its 25,000mAh PB205 at 14,500mAh at 5V (UGREEN).
2. Match the watts to your phone
The watt figure is the fastest the bank can charge. For iPhone 15 and later, Apple's fast-charging page asks for an 18W or higher USB-C adapter that supports USB-PD (Apple), and a 20W PD bank such as the UGREEN 10000mAh Power Bank PD 20W meets that.
For other phones, check the wattage and fast-charging standard (PD or Quick Charge) on the phone's own charger, and pick a bank that matches. The Ultima Boost 10k Mini, for example, lists 22.5W with both Power Delivery and QC 3.0.
3. Magnetic wireless for iPhone
Magnetic power banks like the Joyroom JR-W020, the Mcdodo MC-426 and MC-502, and the WiWU SC5000A Snap Cube stick to the back of the phone, so there's no cable. Apple's MagSafe page lists the iPhone 12 models through to the iPhone 18 Pro, and names the iPhone 16e as a non-MagSafe model (Apple). Other phones need a magnetic case or ring. Wireless is handy, but a cable usually charges faster.
4. Charging a laptop
A laptop that charges over USB-C can run from a power bank with enough watts, so compare the bank's watts with your laptop charger's. The UGREEN PB205 25000mAh 145W is built for laptops. UGREEN lists the MacBook Air, Dell XPS and ThinkPad among compatible models, and says it recharges in about 2 hours on a 65W PD charger (UGREEN).
The UGREEN 20000mAh PD 45W and Trusmi PB14-011 20000mAh 45W charge at up to 45W, so they suit laptops whose own charger is 45W or smaller.
5. Flying with a power bank
Under IATA guidance issued in March 2026, power banks go in cabin baggage only, up to 100Wh each and no more than two per person. They must not be recharged on board, and IATA recommends not using them to charge devices in flight (IATA). Airlines can set stricter rules and the rules get updated, so check with yours before you fly.
The Wh figure is printed on the bank, or you can work it out: mAh × 3.7 ÷ 1,000. A 10,000mAh bank is 37Wh and a 20,000mAh bank 74Wh. UGREEN rates the 25,000mAh PB205 at 90Wh (UGREEN).

Power bank FAQ
How many times will a 10,000mAh power bank charge my phone?
About 1.4 times for a 4,500mAh phone and about twice for a 3,000mAh phone. UGREEN says a 10,000mAh bank usually delivers 6,000 to 7,000mAh, because some energy is lost in conversion.
Can I take a power bank on a flight?
Yes, in your cabin bag, not checked luggage. IATA guidance allows up to 100Wh per bank and no more than two per person, and says not to recharge them on board. A 20,000mAh bank is about 74Wh. Check your airline's rules too.
Which power bank is good for an iPhone?
A 20W USB-C PD power bank fast charges iPhone 15 and later. For no cable at all, a magnetic one snaps onto a MagSafe iPhone, which means the iPhone 12 or newer except the iPhone 16e.
Can a power bank charge a laptop?
Yes, if the laptop charges over USB-C and the bank has enough watts, so compare it with your laptop's charger. The UGREEN PB205 25000mAh 145W is made for laptops, and the 45W models suit laptops with a 45W or smaller charger.
Which power bank brands do you sell?
Havit, Joyroom, Mcdodo, Trusmi, UGREEN, Ultima and WiWU. Every price on this page is our current website price.
Do you deliver power banks outside Birtamode?
Yes. We usually deliver all over Nepal in 2 to 5 days, and delivery is free within 15 km on products over Rs 5,000.
