Quick answer: our top pick is INIU 20000mAh 45W (20,000 mAh · 45 W USB PD · built-in USB-C cable).
Best power bank for Galaxy S26? For the S26+, choose a 45 W version with PPS
For the Galaxy S26, the Samsung 10,000 mAh 25 W is enough. It has Super Fast Charging, meaning PPS, so the phone gets the full 25 W it can accept.
For the Galaxy S26+, look for a power bank with PPS and 45 W of power. The Samsung 20,000 mAh 45 W or the Baseus QPow3 20,000 mAh are a good fit. You can plug the S26 into them too, but it will draw only its own 25 W.
The Galaxy S26 has a 4300 mAh battery and wired charging up to 25 W with PPS. The S26+ has 4900 mAh and up to 45 W with PPS (Super Fast Charging 2.0). There is no charger in the box, so a power bank with good output often doubles as a second charger.
The Galaxy S26 Ultra has a separate article about power banks, worth checking out if you own that model.
Fun fact: The S26 has a battery 300 mAh larger than the S25, and in GSMArena's test it charged faster than its predecessor, even though the power stayed the same, 25 W.
PPS: why charging is slower without it
PPS is a mode in which the phone continuously negotiates voltage and current with the charger. Samsung uses it in Super Fast Charging, which is why the Galaxy S26 and S26+ work best with power banks that support it. Without PPS, the phone usually charges more slowly than it could.
What this looks like in practice is shown by GSMArena's test of the S26+: 38% after 15 minutes, 69% after 30 minutes and 100% after 1 hour and 1 minute. That result was achieved with the full 45 W and PPS.
When choosing, look at the manufacturer's description. PPS is stated explicitly by Baseus QPow3 (PD 3.0/PPS 45 W) and Samsung power banks, because Super Fast Charging 2.0 is PPS. INIU, UGREEN and Anker mention USB PD 45 W in their descriptions, but do not mention PPS. This does not mean they charge more slowly, only that the manufacturer does not confirm PPS in the description.
The INIU 20,000 mAh 45 W declares support for PD, QC and other fast charging protocols, as well as charging a Samsung S25 Ultra to 80%. That is the manufacturer's claim. This model is the number 1 power bank on Amazon, and the INIU Ultra Mini 10,000 mAh takes second place.
Below we have gathered power banks selected by whether the manufacturer states PPS or the full 25 W and 45 W, and whether they suit everyday carrying.
Recommended power banks for Galaxy S26 and S26+
1. INIU 20000mAh 45W
20,000 mAh · 45 W USB PD · built-in USB-C cable
The number one power bank on Amazon. 20,000 mAh, up to 45 W over USB-C and a built-in cable, so there is no extra cable to carry.
2. Samsung Battery Pack 20000mAh 45W
20,000 mAh · 45 W Super Fast Charging 2.0 (PPS) · 3 ports
Samsung's own power bank with Super Fast Charging 2.0, which means the PPS that Galaxy phones need for full speed. A 5 A USB-C cable is included, three ports.
3. Baseus PicoGo AM52 Qi2.2 25W 10000mAh
10,000 mAh · magnetic Qi2.2 25 W · 45 W over USB-C · 0.6 in thin
Qi2.2 certified, so iPhone 16 and 17 models charge wirelessly at the full 25 W. Over USB-C it delivers 45 W, enough for a Samsung too. Baseus quotes 45% on an iPhone 17 Pro in 30 minutes.
Wireless charging: Qi2, magnets and cases
The Galaxy S26 is Qi2 Ready up to 15 W, and the S26+ has Qi2.2 up to 20 W. Neither has built-in magnets in the body. A magnetic power bank will therefore only stay in place with a case that has a magnet.
If you plan to use a magnetic power bank, buy a case with magnets first. Without them, the power bank will slide off and the coils will stop lining up. The best-selling magnetic power bank on Amazon is the Anker Nano Qi2.
The Baseus PicoGo AM52 Qi2.2 25 W 10 000 mAh is a good choice for someone who has both Samsung phones and an iPhone at home. It delivers 45 W over USB-C, so you can also charge a Samsung with a cable.
Keep in mind that wireless charging loses more energy than charging with a cable. You will get fewer charges from the same power bank, and the phone will charge more slowly than with a wire.
Fun fact: The S26 has Qi2, but no magnets in the body, so a magnetic power bank requires a case with a magnet (GSMArena).
How many charges 10 000 and 20 000 mAh give, and what about carry-on luggage
Power bank capacity is stated for 3.7 V cells. 10 000 mAh is about 37 Wh, and 20 000 mAh is about 74 Wh. Some of the energy is lost in the converters. Anker states that its 25 000 mAh power bank charges a Galaxy S23 (3900 mAh) 4.7 times, which means about three quarters of the cell energy reaches the phone.
Hence a simple estimate: power bank capacity x 0.72 / phone battery capacity. This is an approximate value.
- Galaxy S26: about 1.7 charges from 10 000 mAh, about 3.3 charges from 20 000 mAh.
- Galaxy S26+: about 1.5 charges from 10 000 mAh, about 2.9 charges from 20 000 mAh.
For a weekend or a day away from home, 10 000 mAh is enough. For several days without a power outlet, or when you are also charging earbuds and a second phone, take 20 000 mAh.
On a plane, power banks up to 100 Wh can usually be carried only in carry-on luggage. 20 000 mAh and 25 000 mAh fit within this limit, and for example the Anker 165 W is 90 Wh. Never put a power bank in checked luggage.
Frequently asked questions about a power bank for the Galaxy S26
Which power bank for the Galaxy S26?
The simplest choice is the Samsung 10 000 mAh 25 W with PPS, which gives the S26 full power. If you want a larger capacity, go for a 20 000 mAh model with PPS 45 W, for example from Samsung or the Baseus QPow3. The S26 will draw its 25 W from it.
Does the Galaxy S26 need a power bank with PPS?
For full speed, yes. The S26 supports 25 W charging with PPS (Super Fast Charging), and a power bank without PPS may charge more slowly. That is why it helps when the manufacturer states PPS directly in the description.
Which power bank for the Galaxy S26+ with 45 W charging?
Choose a power bank with PPS 45 W. The Samsung 20 000 mAh 45 W (Super Fast Charging 2.0) and the Baseus QPow3 20 000 mAh, which lists PD 3.0/PPS 45 W, both fit. Both give the S26+ full power.
Does a magnetic power bank fit the Galaxy S26?
It does, but only with a case with a built-in magnet, because the phone itself has no magnets. The S26 charges wirelessly up to 15 W (Qi2 Ready), and the S26+ up to 20 W (Qi2.2). With a cable it will be faster and with lower losses.
How many times will a 10 000 mAh power bank charge the Galaxy S26?
Roughly 1.7 times. This is an approximate result, because some of the energy is lost in the converters. For the S26+ it comes out at about 1.5 times.
