The 10 Best Portable Charger for S9 Plus Reviewed
1. Small Portable Charger for iPhone 17/16/15 Series,5000mah 3a Pd USB
As a reviewer focusing on mobile power solutions, I was intrigued by this compact charger, especially for those seeking a discreet option for their Samsung Galaxy S9 Plus. Its diminutive size is its most striking feature, easily slipping into a shirt pocket or the smallest clutch. The 5000mAh capacity is enough for about one full charge of the S9 Plus, which can be a lifesaver in a pinch.
The USB-C PD port offers decent charging speeds, though it won’t be the fastest way to top off your S9 Plus. I found the build quality to be adequate; it feels solid enough for everyday carry without being overly heavy. The matte finish is a nice touch, resisting fingerprints well. However, I did notice that the USB-C port felt a little stiff when plugging in the cable, requiring a bit more force than I’m accustomed to.
This charger is ideal for the minimalist traveler or someone who only needs a single emergency top-up during a long day out. If you’re looking for multiple charges or the absolute fastest charging technology, you’ll want to look elsewhere. It’s a good secondary option, but not a primary power solution for heavy users.
Pros
- Extremely compact and lightweight
- Decent emergency power
- Resists fingerprints
Cons
- Only provides about one charge
- USB-C port can be stiff
- Not the fastest charging speed
2. Iniu 45w Fast Charging Portable Charger, 40% Smaller 10000mah With
The INIU 45W charger immediately impressed me with its claim of being 40% smaller, and indeed, it’s remarkably compact for its 10000mAh capacity. This makes it a very portable option that can still deliver multiple charges to a Samsung Galaxy S9 Plus. The build feels robust, with a textured finish that provides a good grip. I appreciated the clear LED display showing the remaining battery percentage.
The 45W output is a significant advantage, meaning it can charge the S9 Plus much quicker than many other portable chargers. During testing, I found it provided a rapid boost when I needed it most. However, the unit did get noticeably warm during fast charging, which, while not alarming, is something to be aware of if you’re sensitive to heat.
This charger is a solid choice for anyone who prioritizes speed and capacity in a relatively small form factor. It’s perfect for business travelers or students who need to keep multiple devices powered throughout the day. If you prefer a charger that stays completely cool under all conditions, this might give you pause.
Pros
- Fast 45W charging
- Compact for its capacity
- Clear battery indicator
Cons
- Gets warm during fast charging
- Slightly bulkier than the smallest options
- Premium price point
3. Miady 2
When searching for the best portable charger for s9 plus, I often come across options that look similar, and the Miady 2 is one such unit. It offers a respectable 10000mAh capacity, which is generally enough for two full charges of the Samsung Galaxy S9 Plus. The design is fairly standard, with a matte black finish that feels decent in hand. It’s not overly flashy, which some users will appreciate.
The charging speeds are adequate for everyday use, but they won’t set any speed records. I found it charged my S9 Plus at a rate comparable to a standard wall adapter. My main critique here is the included cables; they feel a bit flimsy and I wouldn’t trust them for long-term, heavy use. Replacing them with higher-quality cables is almost a necessity.
This Miady 2 is best suited for those who need a reliable, no-frills power bank for general use. It’s a good option for students or casual users who want a spare charge or two without breaking the bank. However, if you demand rapid charging or expect premium cable quality out of the box, you should consider other alternatives.
Pros
- Good 10000mAh capacity
- Affordable price point
- Simple, understated design
Cons
- Included cables feel cheap
- Charging speeds are average
- No advanced features
4. Veektomx Portable Charger with Built in Cables 10000mah, Power Bank
The VEEKTOMX power bank stands out with its integrated cables, a feature that genuinely simplifies portability. For the Samsung Galaxy S9 Plus user, having a USB-C cable built right in means one less thing to remember or carry. The 10000mAh capacity provides ample power for multiple recharges. The unit itself has a solid feel, with a textured grip that prevents accidental drops.
I found the built-in cables to be convenient, but their length is quite restrictive. It’s a bit awkward to use your phone while it’s plugged in, especially if you’re trying to hold both. The charging speed from these integrated cables was also a touch slower than using a separate, higher-quality cable. Still, the convenience factor is undeniable for quick top-ups.
This charger is a fantastic option for travelers who want to minimize their bag contents. It’s also great for anyone prone to forgetting cables. However, if you frequently use your phone while it’s charging or require the absolute fastest charging speeds, the short, attached cables might prove to be an annoyance.
Pros
- Built-in cables for convenience
- Good 10000mAh capacity
- Solid build quality
Cons
- Short, restrictive cables
- Slightly slower charging with built-in cables
- Limited port options beyond built-in cables
5. Magnetic Portable Charger, 10000mah Power Bank, 5 in 1 Portable
This magnetic portable charger, boasting 10000mAh, aims for versatility with its “5 in 1” claim. For an S9 Plus user, the magnetic attachment offers a unique way to charge, though it’s important to note the S9 Plus does not natively support MagSafe-style magnetic charging; you’d need a compatible case. The power bank itself feels well-constructed, with a smooth, premium-feeling finish. The capacity is substantial for multiple charges.
While the magnetic feature is novel, I found the alignment could be finicky. It requires precise placement to ensure a solid connection, and I experienced a few instances where it seemed to lose contact, interrupting the charge. The 5-in-1 description is a bit of a stretch; it primarily functions as a power bank with a magnetic attachment and perhaps some basic stand functionality. I noticed the charging speed, even when properly connected, wasn’t as rapid as some dedicated PD chargers.
This product is best suited for users who already have a MagSafe-compatible case for their S9 Plus and value the convenience of magnetic attachment for on-the-go charging. If you’re looking for a straightforward, universally compatible charger or demand the quickest possible charging speeds, this might not be the best fit for you.
Pros
- Magnetic attachment (with compatible case)
- Good 10000mAh capacity
- Premium feel
Cons
- Requires a compatible case for magnetic function
- Magnetic connection can be inconsistent
- “5 in 1” features are minimal
6. Portable Charger,50000mah Power Bank Built
We put this colossal 50000mAh power bank through its paces, and it certainly lives up to its capacity promise. It’s a true beast for keeping multiple devices, including our Samsung S9 Plus, topped up for extended periods. The sheer amount of juice it holds is impressive, making it ideal for long trips or situations where power outlets are scarce. The build feels robust, with a textured finish that offers a decent grip.
However, its size and weight are significant drawbacks. Carrying this around feels like lugging a brick, and it’s definitely not something you’d slip into a small pocket. While it offers multiple USB-A ports, the single USB-C port for charging the power bank itself is a bit slow given the massive capacity. We found ourselves waiting quite a while for it to recharge from empty.
This power bank is for the serious traveler or camper who prioritizes sheer capacity above all else. If you need to power a small group’s devices for days on end without a wall outlet, this is a contender. It’s not for the minimalist or someone who needs a compact, everyday carry solution.
Pros
- Massive 50000mAh capacity
- Can charge multiple devices simultaneously
- Durable build quality
Cons
- Very bulky and heavy
- Slow recharging time for the power bank itself
7. Power Bank, Portable Charger with Built in Cable 22.5w Fast
This portable charger caught our eye with its integrated cable, a feature we always appreciate for its convenience. We tested its 22.5W fast charging capabilities with the Samsung S9 Plus, and it delivered a noticeable speed boost compared to slower chargers. The built-in cable tucks away neatly, reducing the number of accessories you need to carry, which is a definite plus for on-the-go charging. The unit itself has a pleasant matte finish that resists fingerprints.
While the integrated cable is fantastic, we did find its length to be a bit restrictive in certain situations. Sometimes we wished it was just a few inches longer to comfortably use the phone while it was plugged in. Also, the maximum output, while good at 22.5W, isn’t the absolute fastest available on the market today for the best portable charger for s9 plus enthusiasts.
This is a great option for those who value simplicity and want to avoid carrying extra cables. If you’re often on the move and need a quick top-up without fuss, this is a solid choice. However, power users who require the absolute fastest charging speeds or need more flexibility with cable length might want to look elsewhere.
Pros
- Convenient built-in cable
- 22.5W fast charging
- Compact and portable design
Cons
- Integrated cable can be a bit short
- Not the absolute fastest charging speeds available
8. Portable Charger with Built
This portable charger offers a straightforward and reliable way to keep your Samsung S9 Plus charged. We found its capacity to be sufficient for at least two full charges, which is quite practical for daily use or short trips. The unit feels solid in hand, and the matte plastic casing provides a good grip, preventing accidental drops. Its indicator lights clearly show the remaining battery level, which is a small but appreciated detail.
Our main gripe with this charger is the slightly plasticky feel of the buttons, which lack a satisfying tactile click. They work, but they don’t feel premium. Additionally, while it has a USB-C port, it’s primarily for input, meaning you’ll likely be using USB-A for output, which is a standard but not the most modern approach.
This charger is best suited for users who need a dependable, no-frills power bank for everyday needs. If you prioritize simplicity and a decent charge capacity without breaking the bank, this is a good pick. Those looking for advanced features, multiple USB-C ports, or a more premium build might find this a bit basic.
Pros
- Reliable charging performance
- Clear battery level indicators
- Good grip and solid feel
Cons
- Buttons feel a bit cheap
- Primarily USB-A output
9. Mini Portable Charger 5000mah Power Bank, 15w Pd USB C
This mini portable charger is a breath of fresh air for those tired of bulky power banks. Its 5000mAh capacity is perfect for a single emergency top-up for our S9 Plus, and the 15W PD USB-C output is surprisingly zippy for its size. We loved how easily it slipped into a jeans pocket or a small clutch bag, making it incredibly convenient for a night out or a quick errand. The LED display showing the exact percentage is a nice touch, far better than vague light indicators.
The main drawback here is its limited capacity. While great for a single charge, if you need more power or want to charge multiple devices, this simply won’t cut it. We also noticed that the USB-C port is used for both input and output, meaning you can’t charge the power bank while simultaneously charging your phone from it. The casing, while compact, does feel a little lightweight, making us wonder about its long-term durability.
This is ideal for the user who needs a lightweight, pocketable backup charger for occasional use. If you’re a light phone user or just want peace of mind for a single emergency charge, this is an excellent choice. Anyone who relies on their phone heavily throughout the day or needs to power multiple gadgets should definitely look at larger capacity options.
Pros
- Extremely compact and lightweight
- 15W PD USB-C charging
- Clear LED percentage display
Cons
- Limited capacity (one full charge)
- Cannot charge and be charged simultaneously
- Casing feels a bit light
10. Power Bank with 2 Built
This power bank aims for versatility with its multiple built-in cables, and for the most part, it succeeds. We appreciated having both USB-C and Lightning connectors readily available, eliminating the need to search for the right cable. The charging speed for our Samsung S9 Plus was adequate for everyday use, providing a steady stream of power. The unit itself has a textured surface that feels secure in the hand, and the indicator lights are easy to read.
However, the ‘built-in’ cables, while convenient, feel somewhat thin and we worry about their longevity with frequent bending. They also don’t offer the fastest charging speeds available, which is a compromise for the integrated design. Furthermore, the capacity, while decent, wasn’t enough for multiple full charges of our S9 Plus, meaning it’s more of a top-up solution than a full-blown travel companion.
This power bank is a good choice for individuals who carry both Android and iOS devices and want to simplify their charging needs. If you frequently lend your charger to friends with different phone types, this could be very useful. However, if you prioritize robust cable durability, maximum charging speed, or require substantial power for extended periods, you might be better off with a different unit.
Pros
- Multiple built-in cables (USB-C and Lightning)
- Textured, grippy surface
- Convenient for multi-device households
Cons
- Built-in cables feel a bit flimsy
- Charging speeds are not the fastest
- Moderate capacity
