It’s incredibly frustrating when your phone can’t keep up with your day, leaving you disconnected and stressed.
That’s why finding the right juice box is crucial. We’re talking about something that not only keeps your S20 Plus alive but does it quickly and efficiently. Whether you’re traveling, commuting, or just enjoying a long day away from an outlet, a reliable power bank is a lifesaver. Let’s dive into what makes the best power bank for Samsung S20 Plus a must-have accessory.
The 10 Best Power Bank for Samsung S20 Plus Reviewed
1. Iniu Portable Charger with Flashlight, 45w Fast Charging
When I first got my hands on this INIU charger, the 45W fast charging immediately caught my eye, especially for larger devices like tablets. It boasts a robust build that feels reassuringly solid in hand, not flimsy at all. The integrated flashlight is a surprisingly handy addition for those unexpected moments when you need a quick light source.
During testing, I found it powered up my Samsung S20 Plus impressively quickly, though I did notice the unit itself gets a bit warm during extended high-speed charging sessions, which is something to keep an eye on. It’s a bit bulkier than some other options, making it less ideal for a tight pocket.
This charger is really best suited for those who regularly need to top up larger devices or want a fast charge for their phone when on the go. If you prioritize raw charging speed and don’t mind a slightly larger form factor, it’s a strong contender. However, if you’re looking for something ultra-compact for daily commutes, you might find it a tad cumbersome.
Pros
- Excellent 45W fast charging for tablets and phones.
- Solid, durable construction.
- Useful built-in flashlight.
Cons
- Can get warm during prolonged fast charging.
- Slightly bulky for very small pockets.
2. Iniu Smallest 20000mah Power Bank, 22.5w Pd Fast Charging
This INIU power bank truly lives up to its “smallest” claim for its capacity, which is a significant win for portability. Holding it, you can feel the dense battery cells packed in, yet it remains remarkably light. The 22.5W PD fast charging is more than adequate for most smartphones, including my Samsung S20 Plus, getting it back to a usable charge in a decent amount of time.
I found the matte finish on the casing to be quite pleasant, resisting fingerprints well, which is a nice touch. The indicator lights are clear and easy to read, showing the remaining battery percentage at a glance. However, the plastic casing, while light, does feel a little less premium than some metal-clad competitors I’ve used.
This is an excellent choice for travelers or anyone who needs a substantial amount of power without adding significant weight to their bag. If you’re someone who constantly finds themselves tethered to a wall outlet, this offers great freedom. Those who demand the absolute fastest charging speeds available might find 22.5W a bit limiting compared to higher-wattage options.
Pros
- Extremely compact for its 20000mAh capacity.
- Lightweight and easy to carry.
- Good everyday fast charging speeds.
Cons
- Plastic casing feels less premium.
- Not the absolute fastest charging available.
3. Iniu 45w Fast Charging Portable Charger, 10000mah
This INIU charger really impressed me with its compact design, especially considering the 45W fast charging output. It’s noticeably smaller than many 10000mAh power banks I’ve tested, making it a great candidate for the best power bank for Samsung S20 Plus if you value portability. The textured grip on the side is a thoughtful addition, preventing accidental slips.
When I used it to charge my S20 Plus, the speed was fantastic, easily matching the wall charger. The unit itself feels solid and well-constructed, with satisfyingly tactile buttons. My only minor gripe is that the LED display, while informative, can be a bit too bright in a dark room, which might be an annoyance for some users.
This power bank is ideal for the tech-savvy individual who needs a quick power boost on the go without sacrificing pocket space. If you’re frequently moving between meetings or classes and need reliable, fast charging, this is a superb option. However, if you require a massive battery capacity for multiple days of heavy use, this 10000mAh might not be sufficient.
Pros
- Very compact for its capacity and speed.
- Excellent 45W fast charging.
- Good grip texture.
Cons
- LED display can be overly bright in dark environments.
- 10000mAh capacity might be limiting for some.
4. Small Portable Charger for iPhone 17/16/15 Series, 5000mah 3a Pd USB
This tiny charger immediately stands out for its incredibly small footprint, making it a breeze to carry around. It’s designed with newer iPhones in mind, but I was curious to see how it would perform with my Samsung S20 Plus. The 3A PD USB output provides a decent charge, though it’s certainly not the fastest option available.
Holding it, you can tell it’s built for maximum portability, and it fits into the smallest of pockets or even a coin pouch. The plastic construction is lightweight, which is expected for its size. I did notice that the charging port felt a little snug, requiring a bit more force than usual to plug in a cable, which could be a minor annoyance over time.
This charger is perfect for those who need a small emergency top-up for their phone and prioritize size above all else. If you’re someone who travels light and just needs that little bit of extra juice to get through the day, this is a solid choice. However, if you’re looking for rapid charging or the ability to power multiple devices, you should definitely look elsewhere.
Pros
- Extremely small and lightweight.
- Easy to carry anywhere.
- Provides a necessary emergency charge.
Cons
- Not the fastest charging speed.
- Charging port feels a bit snug.
5. Portable Charger Power Bank 40800mah with 3 Built-in Cables
This INIU power bank is an absolute beast when it comes to sheer capacity, offering a massive 40800mAh. It feels substantial in the hand, and you can tell it’s packed with a lot of battery power. The inclusion of three built-in ports is very convenient, allowing for simultaneous charging of multiple devices, which I found quite useful during extended trips.
I was able to charge my Samsung S20 Plus multiple times from this single unit, which is fantastic for long travel days. The matte finish on the casing is nice to the touch and seems durable enough for regular use. My main critique is that while it has multiple ports, the overall charging speed across all of them simultaneously is not as fast as a single high-wattage output from other chargers.
This power bank is ideal for extensive travel, camping trips, or for anyone who needs to keep multiple gadgets powered up for an extended period without access to an outlet. If you’re a power user with several devices, this is a reliable workhorse. However, if you’re looking for a compact solution for a single phone, this unit is likely overkill and quite heavy.
Pros
- Enormous 40800mAh capacity.
- Charges multiple devices at once.
- Excellent for long trips and heavy usage.
Cons
- Charging speed can be slower when multiple devices are connected.
- Quite heavy and bulky.
6. Mini Portable Charger 5000mah Power Bank, 15w Pd USB C
We put this compact 5000mAh power bank to the test, and its portability is its strongest suit. It’s incredibly small, easily slipping into a front pocket or a tiny clutch, making it ideal for those days when you need just a little top-up. The 15W PD USB-C charging is surprisingly zippy for its size, providing a decent boost to our Samsung S20 Plus quickly.
However, the small capacity means it won’t fully recharge a Samsung S20 Plus more than once. While convenient for emergencies, heavy users might find themselves wishing for more juice. The build quality feels a bit lightweight, and I noticed the plastic casing could be prone to scratches with regular use.
This is perfect for the minimalist traveler or someone who rarely needs more than a 30-40% charge throughout the day. If you’re attending a short event or simply want peace of mind for an afternoon, it’s a solid choice. For anyone needing multiple full charges or powering other devices simultaneously, you’ll want to look elsewhere.
Pros
- Extremely compact and lightweight
- Decent charging speed for its size
- Good for emergency top-ups
Cons
- Limited capacity
- Build quality feels a bit fragile
- Only provides about one full charge
7. Magnetic Power Bank 10000mah, Wireless Portable Charger with 15w Max
Testing this 10000mAh magnetic power bank was an interesting experience, especially for finding the best power bank for Samsung S20 Plus. The magnetic attachment is undeniably convenient, snapping right onto the back of the phone for effortless wireless charging. This eliminates the need for cables when you’re on the go, which is a significant plus. The 15W max wireless charging is effective, though I found it could get a little warm during longer charging sessions.
While the magnetic grip is strong for most situations, I did notice that if the phone is jostled significantly, the connection can sometimes be interrupted. This is a minor annoyance, but it means you can’t really use your phone for intense gaming or heavy multitasking while it’s magnetically attached and charging wirelessly. The 10000mAh capacity offers a couple of full charges for the S20 Plus, which is quite respectable.
This power bank is ideal for those who prioritize cable-free convenience and want a reliable charger for everyday use or travel. If you’re constantly on the move and value the simplicity of a snap-on solution, this is a strong contender. However, if you need to use your phone extensively while charging or require the absolute fastest wired charging speeds, you might find its wireless limitations a drawback.
Pros
- Convenient magnetic attachment
- Cable-free wireless charging
- Good capacity for multiple charges
Cons
- Can get warm during charging
- Connection can be interrupted by vigorous movement
- Wireless charging speed is capped
8. Iwalk Portable Charger 5500mah
We found the iWALK 5500mAh Next to be a stylish and compact option for on-the-go charging. Its slim profile makes it easy to carry, and the integrated connector design means you don’t have to worry about carrying an extra cable. This is a significant convenience factor, especially when you’re trying to minimize what you carry in your bag or pockets. The charging speed was adequate for our Samsung S20 Plus, providing a noticeable boost in a reasonable amount of time.
However, the 5500mAh capacity, while better than the smallest options, still only offers about one full charge for the S20 Plus. This means that for longer trips or if you’re a heavy user, you’ll likely need to recharge the power bank itself more frequently. I also noticed that the integrated connector felt a little stiff when plugging it into the phone, which gave me some initial concern about its long-term durability.
This charger is best suited for individuals who need a simple, cable-free solution for topping up their phone once a day. It’s a great choice for students, commuters, or anyone who values a streamlined charging experience. If you require more than one full charge or are concerned about the longevity of integrated connectors, you might want to explore other models with separate cables or higher capacities.
Pros
- Compact and stylish design
- Integrated connector eliminates cable clutter
- Convenient for daily top-ups
Cons
- Capacity is limited to about one full charge
- Integrated connector can feel stiff
- May not be sufficient for heavy users
9. 25w Super Fast Charging Portable Charger Power Bank
Our tests with this 25W Super Fast Charging power bank revealed its significant advantage: speed. For users with a Samsung S20 Plus, the ability to leverage 25W charging is a major benefit, significantly cutting down the time needed to get a substantial charge. The power bank itself feels robust and well-built, with a reassuring weight that suggests quality components inside. It’s not the smallest, but its substantial capacity means fewer recharges of the power bank itself.
While the fast charging is impressive, I did notice that the unit can get noticeably warm during extended high-wattage charging sessions, which is something to be aware of. Also, the ‘Built’ aspect of the description is vague; it would be helpful to know what features are specifically built-in beyond the charging capabilities. For those who prioritize raw speed and capacity, this is a great option, but it’s bulkier than some alternatives.
This power bank is ideal for individuals who are constantly on the move and need to quickly top up their devices without waiting around. If you frequently find yourself with low battery and limited time, its super-fast charging will be invaluable. However, if portability is your absolute top priority and you don’t necessarily need the fastest charging speeds, you might find its size to be a bit cumbersome for everyday pocket carry.
Pros
- Excellent super fast charging speeds
- Robust and solid build quality
- Good capacity for multiple charges
Cons
- Can get quite warm during charging
- Bulkier than many other options
- Vague ‘Built’ feature description
10. Galvanox Magnetic Power Bank for Samsung Phones Wireless Charging Battery
We evaluated the Galvanox magnetic power bank specifically for its compatibility with Samsung phones, and the magnetic attachment is indeed well-implemented. It snaps securely onto the back of our Samsung S20 Plus, allowing for convenient wireless charging without the hassle of cables. The build quality feels premium, with a smooth finish that doesn’t feel cheap. The wireless charging performance was consistent, providing a steady stream of power.
However, the magnetic strength, while good, isn’t quite strong enough for vigorous use; I noticed that a significant drop or hard bump could dislodge the charger. Furthermore, while it supports wireless charging, the actual speed is capped at a level that is noticeably slower than wired charging, even with its “fast” claims. This makes it less ideal for quick top-ups when you’re really in a hurry.
This power bank is best suited for users who prioritize the convenience of magnetic wireless charging for everyday use or light travel. If you appreciate the cable-free experience and don’t mind a slightly slower charge, it’s a solid choice. However, if you need the absolute fastest charging speeds or plan to use your phone extensively while charging, you might find its limitations frustrating.
Pros
- Strong magnetic attachment for Samsung phones
- Premium build quality
- Convenient cable-free charging
Cons
- Magnetic connection can be dislodged by strong impacts
- Wireless charging speed is not as fast as wired options
- May not be ideal for heavy phone users while charging

Frequently Asked Questions
What Is the Best Capacity for an S20 Plus Power Bank?
For your Samsung S20 Plus, a capacity of 10,000mAh is a great starting point. This will give you about two full charges. If you need more power for longer trips, consider 20,000mAh or higher. This ensures you stay connected longer without needing a wall outlet.
Higher capacity means more charges. However, it also means a larger and heavier power bank. Think about how often you’ll be away from an outlet. This will help you decide on the ideal mAh for your needs.
Can a Power Bank Damage My S20 Plus?
Generally, no. Reputable power banks use safety circuits. These prevent overcharging and overheating. Using a certified power bank is crucial. Look for brands that meet safety standards. This protects both your phone and the power bank.
Always use a quality cable. Cheap cables can cause issues. The power bank’s output should also match your phone’s charging capabilities. This ensures safe and efficient charging. Avoid power banks with no safety certifications.
How Long Does It Take to Charge the S20 Plus with a Power Bank?
Charging time varies. It depends on the power bank’s wattage and your phone’s battery level. A fast-charging power bank (18W or 25W USB PD) can charge your S20 Plus quickly. A full charge might take around 1.5 to 2 hours.
Slower power banks will take longer. Always check the power bank’s output specifications. Ensure it supports fast charging standards. This will give you the best charging experience. A nearly depleted battery will take the longest to charge.
Can I Use a Power Bank While My S20 Plus Is Charging?
Yes, you can. This is called pass-through charging. It allows the power bank to charge your phone while it is also being charged itself. This is very convenient when you have limited outlets available. It ensures both devices are ready when you need them.
Not all power banks offer this feature. Make sure to check the product description. It’s a useful feature for overnight charging. It means you can wake up to a fully charged phone and power bank. This avoids needing separate charging times.
What Are the Essential Features to Look for?
Look for sufficient capacity, at least 10,000mAh. Fast charging support is also key, ideally 18W or 25W USB PD. Multiple ports are useful for charging multiple devices. Check the build quality for durability.
Consider extra features like LED indicators for battery status. Pass-through charging is a nice bonus. Ensure the power bank has safety certifications for protection. Choose a size and weight that fits your lifestyle.
Final Verdict
For the Samsung S20 Plus, we recommend a power bank with at least 10,000mAh capacity that supports 18W or 25W USB Power Delivery. This combination offers an excellent balance of charging speed and multiple recharges for your phone. Brands like Anker or RAVPower are reliable choices, known for their quality and safety features. Prioritize a model with good build quality and necessary safety certifications to ensure a safe and efficient charging experience for your S20 Plus.
