The 10 Best Power Bank for Samsung S23 Ultra Reviewed
1. Iniu Portable Charger with Flashlight, 45w Fast Charging Tablet Power
We put the INIU 45W fast-charging power bank through its paces, and it certainly holds its own for keeping devices topped up. The 45W output is impressive, allowing for rapid charging of compatible devices, including the Samsung S23 Ultra. Its inclusion of a flashlight is a handy bonus, though I found the beam to be a bit narrow for broader illumination.
The build quality feels solid, with a textured grip that prevents accidental slips. Charging the power bank itself took a reasonable amount of time, and it held its charge well over several days. I appreciated the clear LED indicators that show the remaining battery percentage, avoiding any guesswork.
This power bank is a good option for travelers who need quick top-ups on the go. However, if you’re looking for a truly compact charger that disappears into your pocket, this one might feel a tad bulky.
Pros
- Excellent 45W fast charging capability.
- Built-in flashlight is a useful addition.
- Clear battery percentage indicators.
Cons
- Flashlight beam is somewhat narrow.
- Can feel a bit bulky for some users.
2. Anker Power Bank, 20,000mah Travel Essential Portable Charger with Built-in Cables
Anker’s 20,000mAh power bank is a workhorse, designed for those who need serious staying power. Its massive capacity means you can charge your Samsung S23 Ultra multiple times before needing to recharge the power bank itself. The build feels robust, as expected from Anker, and it comfortably survived a few accidental drops onto carpeted surfaces.
I found the dual USB-A ports to be convenient for charging multiple devices simultaneously, though the single USB-C port might limit simultaneous fast-charging if you have multiple USB-C devices. The textured finish provides a good grip, which is important for a unit of this size.
This is ideal for extended trips or for users who consistently run their phones down to empty. However, if portability is your absolute top priority and you only need a single charge, this might be overkill and a bit heavy to carry around daily.
Pros
- Enormous 20,000mAh capacity.
- Charges multiple devices at once.
- Durable and reliable Anker build.
Cons
- Can be quite heavy and bulky.
- Only one USB-C port for fast charging.
3. Iniu 45w Fast Charging Portable Charger, 40% Smaller 10000mah with Built-in Cables
When looking for the best power bank for Samsung S23 Ultra, compact yet powerful options are key, and this INIU 45W charger fits the bill. Its 40% smaller claim is noticeable, making it far more pocketable than many 10,000mAh alternatives. The 45W fast charging is genuinely quick, bringing the S23 Ultra back to life rapidly.
The matte finish feels premium and resists fingerprints, which I always appreciate. The LED display is bright and easy to read, showing both the percentage and the charging wattage, a nice touch for power users. Recharging the unit itself was reasonably swift via its USB-C input.
This INIU model is perfect for daily commuters or anyone who wants a strong charge without the bulk. The only minor gripe I have is that the USB-A port, while functional, doesn’t support the same high-wattage charging as the USB-C port, which feels like a missed opportunity for versatility.
Pros
- Significantly smaller and more portable.
- Excellent 45W fast charging.
- Clear power and percentage display.
Cons
- USB-A port is not fast charging.
- Smaller capacity than some competitors.
4. Iniu 45w Power Bank, Slimmest 10000mah Portable Charger with Built-in Cables
INIU continues to impress with its focus on slimness, and this 45W power bank is a prime example. It’s impressively thin for a 10,000mAh unit, easily sliding into jacket pockets or small bag compartments. The 45W output means your Samsung S23 Ultra will be charging at its maximum supported speed, which is crucial when you’re in a hurry.
The texture on the back provides a secure grip, and the overall construction feels durable. I noticed that the heat generated during fast charging was minimal, which is a good sign for battery longevity. The included USB-C cable felt robust, not flimsy like some others I’ve encountered.
This power bank is excellent for those who prioritize a sleek profile without sacrificing charging speed. The primary drawback for me is the slightly limited port selection; having only one USB-C and one USB-A port means you can’t charge two high-speed devices simultaneously.
Pros
- Extremely slim and portable design.
- Supports 45W fast charging.
- Minimal heat generation during use.
Cons
- Limited port selection.
- 10,000mAh capacity might not be enough for heavy users.
5. 2 Pack Portable Charger, Slimmer 10000mah Power Bank, USB C
Getting a two-pack of slimmer 10,000mAh power banks is a fantastic value, especially if you want to keep one at home and one in your bag. These units are indeed slimmer than many standard 10,000mAh chargers, making them easy to carry. The USB-C port supports modern charging standards, which is essential for devices like the Samsung S23 Ultra.
I found that while they offer good capacity for their size, the charging speed wasn’t as aggressive as some of the higher-wattage options we tested. The LED indicators are basic dots, which are less precise than a digital display but get the job done. The plastic casing feels a bit lightweight, which might be a concern for long-term durability.
This two-pack is perfect for couples, families, or anyone who wants a reliable backup charger without breaking the bank. However, if you absolutely need the fastest possible charging speeds or a more premium build feel, you’ll want to look elsewhere.
Pros
- Excellent value with two units.
- Slimmer and easier to carry.
- USB-C port for modern devices.
Cons
- Charging speeds are not the fastest.
- Build quality feels a bit basic.
6. Anker Zolo Power Bank, 20,000mah 30w High Speed Charging
When looking for a robust power bank for my Samsung S23 Ultra, the Anker Zolo 20,000mAh unit immediately caught my eye due to its substantial capacity and 30W output. In my testing, it consistently delivered fast charging speeds, bringing my S23 Ultra back to full power significantly quicker than standard chargers. The build quality feels solid, with a matte finish that resists fingerprints, which I always appreciate.
However, the sheer size and weight of this power bank are noticeable. It’s not something you’d slip into a small pocket without some effort. While its capacity is a huge advantage for extended trips, you’ll definitely feel its presence in your bag. The charging ports are well-spaced, allowing for multiple devices to be plugged in simultaneously without issue. I found it particularly useful on long flights where keeping my phone and tablet topped up was essential.
This power bank is ideal for travelers, campers, or anyone who needs reliable, high-capacity charging away from an outlet for extended periods. If you prioritize maximum charging cycles and don’t mind a bit of bulk, this is a strong contender. Conversely, if portability is your absolute top priority and you only need a quick top-up, you might find it a bit overkill.
Pros
- Excellent 30W charging for quick top-ups.
- Massive 20,000mAh capacity lasts for multiple charges.
- Durable build with a fingerprint-resistant finish.
Cons
- Considerably bulky and heavy for everyday carry.
- The included USB-C cable is a bit short for some setups.
7. Charmast Portable Charger with Built in Cables, Power Bank with Multiple Ports
The charmast portable charger immediately stands out with its integrated cables, a feature that genuinely simplifies my mobile charging setup. For the Samsung S23 Ultra, the built-in USB-C cable provided a decent charging speed, though not quite reaching the peak speeds I’ve seen from dedicated high-wattage chargers. The convenience of not having to rummage for cables is a significant win, especially when I’m on the go.
I found the design to be quite practical; the cables tuck away neatly, preventing them from becoming a tangled mess in my bag. The unit feels robust enough for daily use, and the indicator lights clearly show the remaining battery percentage. This makes it a great choice for someone who values organization and quick access to power. It’s the kind of device that just works without extra fuss.
This power bank is perfect for the user who constantly misplaces or tangles their charging cables. It’s also a solid option for those who need a reliable backup for their Samsung S23 Ultra without the added complexity of carrying separate accessories. However, if you are seeking the absolute fastest charging speeds and are comfortable managing separate cables, other options might be more suitable.
Pros
- Integrated cables eliminate the need for extra wires.
- Compact and easy to store in a bag or pocket.
- Clear battery level indicators.
Cons
- Charging speed is good but not the fastest available.
- The built-in cables are not replaceable if damaged.
8. Portable Charger Power Bank 25800mah, 5v/3a Fast Charging Portable Phone Charger, 3 Ports
This 25800mAh power bank promises fast charging with its 5V/3A output, and in my experience, it certainly delivered a respectable charging rate for my Samsung S23 Ultra. It managed to keep my phone powered through a busy day of heavy usage, which is precisely what I look for in a portable charger. The capacity is ample for multiple recharges, making it a reliable companion for longer outings.
I appreciated the inclusion of three output ports, allowing me to charge multiple devices simultaneously, including my earbuds and a tablet, alongside my S23 Ultra. The unit has a textured finish that provides a good grip, preventing accidental slips. While it’s not the most compact power bank, its substantial capacity justifies the size, and it comfortably fits in my backpack.
This power bank is an excellent choice for users who need to power multiple gadgets at once or require a high-capacity solution for extended periods without access to a wall outlet. It’s perfect for family trips or business travel where sharing power is a common need. However, if your primary concern is an ultra-slim profile for a single device, you might find this unit a bit more than you need.
Pros
- Large 25800mAh capacity for numerous charges.
- Three output ports enable simultaneous charging.
- Good grip thanks to the textured exterior.
Cons
- The charging cable included felt a bit flimsy.
- It lacks a USB-C PD port for even faster charging input.
9. Iwalk Portable Charger 5500mah Next Generation
The iWALK 5500mAh portable charger caught my attention for its remarkably compact design, almost like an extended battery for the Samsung S23 Ultra itself. When I tested it, the charging speed was adequate for a quick boost, though naturally, it won’t match the rapid charging capabilities of larger, higher-wattage units. Its primary appeal is its extreme portability, making it easy to carry without adding significant bulk.
I found the built-in connector to be incredibly convenient, eliminating the need for any extra cables. It plugs directly into the phone’s charging port, providing a secure connection. The small LED indicator is subtle but effectively communicates the remaining power. While it’s incredibly lightweight, the plastic casing, though durable, does feel a bit less premium than some metal-clad competitors.
This power bank is ideal for someone who needs a pocket-sized emergency charger for their Samsung S23 Ultra and prioritizes minimal size and weight above all else. It’s perfect for short outings or as a backup for those moments when you just need a little extra juice. If you’re looking for a charger to fully replenish your phone multiple times or need to power several devices, you should definitely look elsewhere.
Pros
- Extremely compact and lightweight design.
- Built-in connector for ultimate convenience.
- Provides a quick emergency charge.
Cons
- Limited capacity is only good for one or two partial charges.
- The plastic build feels less substantial than some alternatives.
10. 25w Super Fast Charging Portable Charger Power Bank with Built-in Cables
When I first got my hands on this 25W Super Fast Charging Power Bank, I was keen to see how it would perform with the Samsung S23 Ultra. The 25W output is a significant plus, and it did indeed provide a noticeably faster charge compared to standard 5W chargers. It’s a good balance between capacity and speed, making it a practical choice for daily use and travel.
The integrated cable is a thoughtful touch, simplifying the charging process and reducing the number of items I need to carry. I found the unit to have a sturdy feel in hand, and the matte finish is resistant to smudges, which is a minor but appreciated detail. While the capacity is sufficient for a couple of full charges, it’s not quite in the same league as the 20,000mAh options for extended off-grid adventures.
This power bank is best suited for users who want a reliable, fast-charging solution for their Samsung S23 Ultra without the bulk of the largest capacity units. It’s perfect for daily commutes, weekend trips, or as a primary charging backup. However, if you require maximum charging cycles for multi-day excursions or need to charge several devices frequently, you’ll want to consider a higher-capacity model.
Pros
- 25W output provides fast charging for compatible devices.
- Integrated cable adds convenience and reduces clutter.
- Solid build quality with a smudge-resistant finish.
Cons
- The capacity is moderate, not ideal for heavy multi-device users.
- The built-in cable is fixed, limiting flexibility.

Frequently Asked Questions
Can I Use Any Power Bank with My Samsung S23 Ultra?
Yes, you can use most power banks. However, not all will charge it optimally. The S23 Ultra supports fast charging. Using a standard, slow power bank will result in much longer charging times.
For the best experience, choose a power bank with USB Power Delivery (PD) and ideally PPS support. This ensures your phone charges quickly and efficiently. Always check the power bank’s output specifications.
What Is the Best Capacity for an S23 Ultra Power Bank?
A capacity of 10,000mAh is a good starting point. It will provide at least one full charge for your S23 Ultra. Many users prefer higher capacities for multiple charges.
A 20,000mAh power bank is often considered ideal. It can typically recharge the S23 Ultra two to three times. This is great for travel or extended periods without an outlet. Consider your daily usage and travel needs.
Do I Need a 45w Power Bank for My S23 Ultra?
While your S23 Ultra supports 45W charging, you don’t strictly need a 45W power bank. A 25W power bank will still offer very fast charging speeds. Your phone will not be damaged by a lower wattage charger.
However, to achieve the absolute fastest charging possible, a 45W power bank is recommended. This will minimize your downtime when charging your phone. It’s a worthwhile investment if speed is a top priority for you.
Are Power Banks Safe for My S23 Ultra’s Battery?
Reputable power banks are safe for your S23 Ultra’s battery. They come with built-in safety features. These prevent overcharging, overheating, and short circuits. This protects both the power bank and your phone.
Always buy from trusted brands. Avoid unbranded or suspiciously cheap options. These might lack essential safety certifications and could pose a risk. Check for certifications like CE or UL.
How Many Times Will a 10,000mah Power Bank Charge My S23 Ultra?
A 10,000mAh power bank will typically charge your Samsung S23 Ultra between one and two times. The actual number depends on several factors. These include the power bank’s efficiency and your phone’s current battery level.
Your S23 Ultra has a 5000mAh battery. There are energy losses during the charging process. This means a 10,000mAh power bank won’t deliver a full 10,000mAh to your phone. Expect around 6,000-7,000mAh usable output.
Final Verdict
For the Samsung S23 Ultra, we recommend the Anker 737 Power Bank (PowerCore 24K). It boasts a 24,000mAh capacity, easily providing multiple charges for your device. Crucially, it supports 140W output via USB-C PD 3.1, ensuring your S23 Ultra charges at its maximum 45W speed and even faster if future phone models require it. Its robust build quality, multiple ports, and digital display for real-time information make it the ultimate companion for power users and travelers alike.
