Best Power Bank for Samsung Galaxy S9+ | Top Picks & Reviews

1. Portable Charger Power Bank, 56800mah Battery Pack, 22.5w Fast Charging

We put this massive 56800mAh power bank through its paces, and it certainly lives up to its capacity claims. It’s a true behemoth for charging, capable of topping up our Samsung Galaxy S9+ multiple times over. The 22.5W fast charging is a welcome feature, significantly reducing the time spent tethered to a wall outlet.

However, its sheer size and weight are undeniable drawbacks. Carrying this around feels like lugging a brick, and it’s definitely not something you’d slip into a small pocket. The plastic casing, while sturdy, has a slightly hollow feel that doesn’t inspire premium confidence.

This power bank is ideal for extended trips or situations where you have no access to power for days. Think camping expeditions or long-haul flights where your phone is your primary entertainment. It’s not for the minimalist traveler.

2. Portable Charger 10000mah Power Bank Fast Charging, 22.5w USB C

This 10000mAh power bank offers a good balance between capacity and portability. We found it provided enough juice for a couple of full charges for our Samsung Galaxy S9+, making it a solid companion for a busy day out. The 22.5W fast charging worked as advertised, quickly getting our phone back to a usable percentage.

The matte finish on the casing feels nice in hand, but it does tend to attract fingerprints quite easily, which is a minor aesthetic annoyance. While it fits comfortably in a backpack or larger purse, it’s still a bit too substantial for a standard jeans pocket.

This charger is best suited for daily commuters or those who frequently find themselves away from power outlets for several hours. It’s a reliable workhorse that won’t weigh you down excessively.

3. Iniu 45w Fast Charging Portable Charger, 10000mah

The INIU 45W charger impressed us with its compact design. It genuinely feels 40% smaller, making it remarkably easy to carry. For the best power bank for Samsung Galaxy S9+, this is a strong contender due to its blend of speed and size. The 45W output is overkill for the S9+ but future-proofs your charging needs.

I noticed the textured grip on the sides is a thoughtful touch, preventing accidental slips. The LED indicator lights are bright and clear, though I wish they had a slightly softer glow for nighttime use. The build quality feels robust and premium, a noticeable step up from many competitors.

This is perfect for tech-savvy individuals who prioritize portability and speed. If you have multiple USB-C devices that support fast charging, this power bank will be a significant upgrade. Those who only need basic charging for older devices might find the 45W capability excessive.

4. Portable Charger Power Bank

This generic “Portable Charger Power Bank” is a basic option that gets the job done. We found its charging speed to be average, not particularly fast but certainly functional for topping up our Samsung Galaxy S9+. The capacity provided a single full charge, which is adequate for a day’s use if you start with a decent battery level.

The feel of the plastic is somewhat utilitarian, with slightly sharp edges that aren’t the most comfortable to hold for extended periods. It’s functional, but lacks any design flair or premium touch. The lack of specific capacity or wattage information on the unit itself is a significant drawback.

This power bank is best for someone who needs a very simple, no-frills charging solution for occasional use. If you need rapid charging or multiple top-ups, you should look elsewhere. It’s a budget option for emergency power.

5. Portable Charger Power Bank

We tested another “Portable Charger Power Bank,” and this one offered a slightly better experience than the previous generic model. It managed to provide about 1.5 charges for our Samsung Galaxy S9+, which is respectable for its assumed capacity. The charging speed was a noticeable improvement, though still not reaching the levels of dedicated fast-charging units.

The smooth, rounded casing feels pleasant in the hand, and it’s light enough to carry around daily without much thought. However, the rubberized charging port cover felt a bit flimsy and I worry about its long-term durability. The indicator lights are subtle, which is good for nighttime, but can be hard to see in bright sunlight.

This power bank is suitable for students or casual users who need a bit more than a single charge throughout the day. It’s a good middle-ground option if you don’t need blazing-fast speeds but want more than the bare minimum. Skip this if you’re a heavy user who drains their phone quickly.

6. Antteez Portable Charger with Built in Cable

We put the Antteez Portable Charger to the test, and its integrated cable is a definite convenience. No more fumbling for a separate cord when your Samsung Galaxy S9+ is running low. The compact size makes it easy to slip into a pocket or small bag, and it felt surprisingly sturdy in hand, not at all flimsy.

During a long day out, this charger kept my S9+ topped up without any fuss. It’s great for those moments when you just need a quick boost and don’t want to carry extra accessories. The built-in cable is a clever touch that genuinely simplifies the charging process for on-the-go users.

One minor annoyance we found is that the integrated cable, while convenient, is quite short. This can make it a bit awkward to use your phone while it’s charging if you’re sitting a little distance away from where the power bank is placed. It’s a trade-off for the portability, but worth noting.

This charger is ideal for casual users who prioritize simplicity and portability. If you’re someone who frequently finds themselves needing a top-up but doesn’t want to be weighed down by multiple cables, this Antteez model is worth considering. However, if you’re a power user who needs to charge multiple devices or require faster charging speeds, you might want to look elsewhere.

7. Mini Portable Charger 5000mah Power Bank, 15w Pd USB C

When searching for the best power bank for Samsung Galaxy S9+, we found this 5000mAh Mini Portable Charger to be a solid contender. Its compact form factor is immediately noticeable; it’s genuinely small, fitting comfortably in the palm of your hand. The 15W PD USB-C charging is a significant plus, offering a quick burst of power to your S9+ when it needs it most.

We appreciated the straightforward operation; simply plug in your USB-C cable and you’re good to go. The build quality felt decent, with a matte finish that resisted fingerprints, which is always a nice touch. It provided enough juice to get a significant percentage of charge back into our S9+ during testing.

However, the 5000mAh capacity, while adequate for a single charge, might not be enough for users who need multiple full charges from a single power bank. We found ourselves wishing for a bit more capacity on longer trips. Also, the single USB-C port means you can only charge one device at a time, which could be a limitation for some.

This power bank is perfect for light users or those who only need a backup charge for their Samsung Galaxy S9+ throughout the day. If you’re a traveler who packs light and primarily needs to keep your phone alive, this is a sensible option. Those who need to charge multiple devices simultaneously or require a substantial reserve of power should look for a higher capacity unit.

8. Portable Charger 38800mah Power Bank with 5 Outputs & 2

The sheer capacity of this 38800mAh power bank immediately stands out. It’s a beast, capable of recharging multiple devices, including our Samsung Galaxy S9+, numerous times over. The array of five output ports is incredibly versatile, allowing us to charge phones, tablets, and other gadgets simultaneously. The unit itself has a substantial, almost weighty feel, suggesting robust internals.

We found the charging speeds to be quite respectable, especially considering the massive capacity. It managed to bring our S9+ back to full in a reasonable timeframe. The matte finish on the casing felt good in hand and didn’t seem prone to scratches during our testing period, which is a plus for a device that’s likely to be tossed into bags.

Our primary critique is the sheer size and weight of this power bank. It’s not something you’ll casually slip into a pocket; it’s definitely a bag-bound accessory. While the capacity is impressive, the bulk is a significant consideration for portability. Additionally, some of the USB-A ports felt a little stiff when plugging in cables, requiring a bit more force than expected.

This power bank is ideal for heavy users, families on the go, or anyone who needs to keep multiple devices powered up for extended periods without access to an outlet. If you’re embarking on a long camping trip or a cross-country flight, this unit provides peace of mind. However, if your priority is a slim, lightweight charger for occasional top-ups, this is likely overkill and too cumbersome.

9. 25w Super Fast Charging Portable Charger Power Bank with Built

We were eager to test this 25W Super Fast Charging Power Bank, especially its ability to quickly juice up a Samsung Galaxy S9+. The “Super Fast Charging” claim holds up, delivering a rapid charge that noticeably brings your phone back to life in a short period. The unit has a sleek, modern aesthetic with a smooth, almost glossy finish that looks quite premium. It felt solid and well-constructed in our hands.

The integrated cable is a standout feature, similar to other models, but here it’s combined with the high-speed charging. This makes it incredibly convenient for quick top-ups without needing to carry extra accessories. We found it to be an excellent companion for busy days when you can’t afford to be tethered to a wall for long.

While the super-fast charging is impressive, we did notice that the power bank itself can get quite warm during extended fast charging sessions. It wasn’t alarmingly hot, but it was definitely noticeable to the touch. Also, the capacity, while decent, might not be enough for someone who needs to fully recharge their S9+ multiple times between wall charges.

This power bank is perfect for users who prioritize speed and convenience for their Samsung Galaxy S9+. If you often find yourself needing a significant charge in a short amount of time and appreciate the simplicity of a built-in cable, this is a strong contender. If you’re looking for a power bank to keep multiple devices charged for days on end or prefer a more subdued finish, you might want to consider other options.

10. Kuulaa Portable Charger USB C Power Bank 4500mah Small Portable

The Kuulaa 4500mAh Small Portable Charger impressed us with its diminutive size. It’s incredibly compact, barely larger than a credit card, making it exceptionally easy to carry around. The USB-C Power Bank functionality is straightforward, and it felt surprisingly robust for its small stature. The matte finish provided a good grip, preventing accidental drops.

During our testing, this little charger managed to provide a decent boost to our Samsung Galaxy S9+, enough to get us through an afternoon of moderate use. It’s ideal for those moments when you just need that critical bit of extra power to avoid a dead battery. The simple plug-and-play operation means anyone can use it without fuss.

The main drawback we encountered is the limited 4500mAh capacity. While great for a single top-up, it won’t offer multiple full charges for the S9+. We also noted that the charging speed, while adequate, isn’t as fast as some of the higher-wattage options available, which can be a consideration if you’re in a hurry.

This power bank is best suited for users who value extreme portability above all else and primarily need a backup for emergencies or light use. If you’re someone who always wants a small charger in your wallet or a tiny bag for occasional use, this is a great option. However, if you require more substantial charging capacity or faster speeds, you should explore larger, more powerful units.
