A good 10,000mAh power bank now costs S$36-S$45 in Singapore, a 20,000mAh one from S$34.90, and every pick here is under the 100Wh flight limit. We priced eight brands on their Singapore stores and Challenger on 2 October 2026.
Year-end trips are close, and the airport now checks how many power banks you carry.
> Quick view: best overall is the Anker Zolo 10K at S$42.90; most good 10,000mAh packs cost S$36-S$45; the catch is the two-per-passenger limit on flights out of Singapore, with no charging on board.
Anker is the safe default, and its Singapore store (anker.com.sg, run by local distributor Tech House) is currently running a storewide sale of up to 50% off. The pick for most people is the Anker Zolo Power Bank 10,000mAh 22.5W with a built-in USB-C cable at S$42.90 (was S$79.90): 37Wh, small enough for a pocket, and the cable is attached so you never forget it. If you want faster charging, the Anker Nano 10,000mAh 45W with a retractable USB-C cable is S$82.90 (was S$99.90). iPhone users can snap on the MagGo Nano Ultra-Slim 5,000mAh Qi2 at S$74.90 (was S$109.90).

UGREEN's official Singapore distributor (ugreen.com.sg) sells the strongest laptop packs for the money. The Nexode 20,000mAh 165W is S$119 (was S$159): it has a built-in USB-C cable, a display, 100W fast recharging, and it is CCC-certified, so it is also accepted on domestic flights within China. If you need more capacity, the 25,000mAh 145W is S$129.99 (was S$239.80), rated 90Wh, which is enough to top up a MacBook Air about once. For a phone, the CCC-certified 10,000mAh 33W with built-in USB-C cable is S$49.99 and the 20,000mAh 20W with LED display is S$49.99 (was S$59.99).

Xiaomi's Power Bank 20000mAh (Integrated Cable) is the cheapest big-capacity pack we found from a major brand: S$34.90 on Xiaomi's Singapore store. Xiaomi rates it at 74Wh and labels it suitable for air travel. It has a built-in USB-C cable plus a spare USB-C and USB-A port, charges three devices at once, and does up to 22.5W, which Xiaomi says takes an iPhone 16 Pro to about 56% in 30 minutes and recharges it about four times. It is heavier than a 10,000mAh pack, so it suits a bag rather than a pocket. If you want something smaller, the Xiaomi 67W Power Bank 10000 (Integrated Cable) is S$49.90 and the Super Slim Magnetic Power Bank 5000 is S$44.90. New mi.com users get 10% off. You can also buy at Xiaomi's stores at VivoCity, Jurong Point, Parkway Parade, Great World and other malls. Best for: families and students who want the most charge per dollar.

Belkin is the brand Apple stocks in its own stores, and Challenger has cut the BoostCharge Power Bank 10K with Integrated Cable to S$39 (was S$69) in black, blue, pink and white.

If you want a bigger one, the UltraCharge Power Bank 20K with Integrated Cable and Display is S$99 (was S$109), and the UltraCharge Pro Laptop Power Bank 25K is S$169 (was S$179). iPhone users who prefer magnetic packs can get the BoostCharge Magnetic Wireless Power Bank 5K with a stand at S$49 (was S$80).

The Integra Ultra 45 is a 20,000mAh power bank with a built-in USB-C cable and 45W output for S$39.95 (was S$79.90), enough to charge a phone several times or give a small laptop a top-up.

Valore is Challenger's own house brand, sold only through Challenger, and it comes with a 3-year warranty on many lines. The Valore PD165W 20,000mAh Power Bank (PD55) is S$84.90 (was S$119), the cheapest 165W pack on this list by about S$34, and it has a display for battery level. The smaller Valore PD45W 10,000mAh (PS02) is S$69.90 (was S$89.90) in white, blue or purple.

From 15 April 2026, the Civil Aviation Authority of Singapore (CAAS) limits passengers on flights departing Singapore to two power banks each. Any extra must be thrown away before you board. Power banks cannot be charged on board, and CAAS advises against using them to charge your phone during the flight. The older rules still apply: power banks go in your cabin bag only, never check-in luggage, and each one must be protected against short circuits, such as in its own pouch.
On capacity, packs up to 100Wh are fine, 100Wh to 160Wh need the airline's approval, and anything above 160Wh is banned. Every pick in this guide is under 100Wh. If you are flying within mainland China, the power bank also needs a clear CCC (3C) mark, enforced since 28 June 2025; the UGREEN 165W, Momax Vital 20K and AUKEY Spark Mini here are CCC-certified. Airlines can be stricter, so check yours before you fly.
We read every price on 2 October 2026 from Anker's, UGREEN's and Xiaomi's Singapore online stores and from Challenger's online store, which carries Belkin, Energea, Valore, Momax and AUKEY. Wh ratings come from the makers' product pages. Retailer markdowns rarely print an end date, so treat every price as "as of 2 October".
For most people, the Anker Zolo 10,000mAh 22.5W with a built-in USB-C cable at S$42.90 on anker.com.sg (read 2 October 2026). Laptop users should get the UGREEN Nexode 20,000mAh 165W at S$119, and the cheapest 20,000mAh from a major brand is Xiaomi's at S$34.90.
Two per passenger, from 15 April 2026 under CAAS rules. They must be in your cabin bag (never checked in), protected against short circuits, and they cannot be charged on board. Each must be 100Wh or less, or 100Wh to 160Wh with the airline's approval.
Yes. A 20,000mAh power bank is usually about 72-74Wh (Xiaomi rates its 20,000mAh at 74Wh), well under the 100Wh limit. Even Anker's 26,250mAh Prime is rated 99.75Wh. Check the Wh figure printed on the pack, because that is what airport security reads.
Only for domestic flights within mainland China, where power banks without a clear CCC (3C) mark have been banned since 28 June 2025. Flights out of Singapore do not require it. The UGREEN Nexode 165W, Momax 1-Power Vital 20K and AUKEY Spark Mini in this guide are CCC-certified.
Xiaomi's Power Bank 20000mAh (Integrated Cable) at S$34.90 on mi.com/sg gives the most capacity per dollar. For a small 10,000mAh, the AUKEY Spark Mini is S$35.90 and the Belkin BoostCharge 10K with built-in cable is S$39 (was S$69) at Challenger, prices read 2 October 2026.
