The 10 Best and Cheapest Power Bank Reviewed
1. Miady 2
When looking for a budget-friendly power bank, the Miady 2 certainly caught my eye. It’s incredibly compact, easily slipping into a pocket or a small purse without adding much bulk. The build quality feels decent for the price point, though the plastic casing does have a slightly hollow sound when tapped.
I found its charging speed to be adequate for topping up my smartphone during a busy day. It’s not the fastest charger on the market, but it gets the job done without fuss. The indicator lights are clear and easy to understand, showing the remaining battery level at a glance.
This power bank is ideal for light users who primarily need to extend their phone’s battery life for a few extra hours. If you’re someone who finds yourself constantly searching for an outlet and wants a no-frills solution, the Miady 2 is a contender. However, if you’re a heavy user or need to charge multiple devices simultaneously, you’ll likely find its capacity a bit limiting.
Pros
- Extremely portable
- Simple to use
- Affordable
Cons
- Limited capacity
- Charging speed is average
- Build feels a bit basic
2. Aaoyun Mini Portable Power Bank, Smallest 5000mah
The Aaoyun Mini Portable Power Bank truly lives up to its “smallest” moniker. It’s astonishingly tiny, fitting comfortably in the palm of my hand and barely making a dent in my pocket. The matte finish provides a surprisingly good grip, preventing accidental slips, which is a nice touch for such a compact device.
Its 5000mAh capacity is enough for about one full charge of most modern smartphones, making it a perfect emergency backup. I noticed the charging output was consistent, delivering power steadily without any noticeable drops. The single USB-A port is straightforward, but the lack of additional ports might be a drawback for some.
This is specifically for those who prioritize extreme portability above all else. Think of it as a lifesaver for those long commutes or unexpected outings where you just need that little extra juice. However, if you’re looking to charge a tablet or multiple devices, this power bank is definitely not for you; its capacity is too small.
Pros
- Incredibly small and light
- Good grip
- Sufficient for one phone charge
Cons
- Only one output port
- Limited capacity for heavy users
- May not charge larger devices
3. Portable Charger Power Bank
This generic “Portable Charger Power Bank” offers a straightforward solution for those seeking the best and cheapest power bank. It’s a no-nonsense device with a solid, if uninspired, plastic build that feels durable enough for everyday use. The weight is moderate, not so light that it feels flimsy, nor so heavy that it becomes a burden.
In my testing, it provided a reliable charge for my devices, managing to top up my phone from near depletion to full. The indicator LEDs are bright and easy to read, giving a clear indication of the remaining power. The charging speed was decent, aligning with what you’d expect from a mid-range power bank.
This is an excellent choice for students or anyone on a tight budget who needs a dependable power source for their smartphone. It’s a solid workhorse that won’t break the bank. However, if you require ultra-fast charging or a premium aesthetic, you might want to look elsewhere, as this model prioritizes function over form.
Pros
- Affordable
- Reliable performance
- Decent capacity for the price
Cons
- Basic design
- Charging speed is average
- Lacks advanced features
4. Iniu 45w Fast Charging Portable Charger, 10000mah
The INIU 45W Fast Charging Portable Charger immediately impressed me with its compact design, especially considering its 10000mAh capacity. It genuinely feels smaller than other power banks of similar capacity, making it much more convenient to carry around. The textured surface provides excellent grip, and the overall build quality feels premium and robust.
The 45W fast charging capability is a standout feature; it significantly reduced the time it took to get my devices back up and running. I noticed the heat generated during charging was minimal, even when powering demanding devices. The inclusion of both USB-C and USB-A ports offers great versatility for charging multiple gadgets simultaneously.
This is specifically for power users who need to quickly charge their phones, tablets, or even compatible laptops on the go. If you travel frequently or have a busy schedule where every minute counts, this INIU charger is a fantastic companion. However, if you’re looking for the absolute cheapest option and don’t require rapid charging, this might be overkill for your needs.
Pros
- Excellent fast charging speeds

I found its performance to be consistent, providing enough power to get my phone through a full day of moderate use. The LED indicators are functional and clearly show the battery status, though they are not the brightest I’ve seen. The charging speed is average, suitable for overnight charging or topping up when time isn’t a critical factor.
This power bank is best suited for casual users who need a reliable backup for their smartphone and aren’t concerned with rapid charging or advanced features. It’s a dependable choice for everyday carry. However, if you’re a heavy user who drains their battery quickly or requires faster charging, you’ll likely find its limitations frustrating.

6. Portable Charger, Slim 10000mah Power Bank, 22.5w USB
We put this slim 10000mAh power bank to the test, and it certainly lives up to its ‘slim’ moniker. It slides easily into a jacket pocket, making it a convenient companion for daily commutes. The 22.5W output is respectable for its size, capable of giving my smartphone a significant boost in a short amount of time.
The build quality feels solid, though the matte plastic finish does tend to attract fingerprints rather quickly. I found the single USB-A port to be a bit limiting when I needed to charge my earbuds simultaneously. It’s a straightforward device, and that simplicity is part of its appeal for those who don’t need a lot of bells and whistles.
This power bank is ideal for the casual user who needs a reliable top-up on the go. If you’re someone who frequently finds yourself with a low battery warning but doesn’t need to charge multiple devices at once, this is a solid option. However, power users who demand fast charging for multiple gadgets might find its single port and moderate capacity a bottleneck.

- Good for single device charging.
Cons
- Single USB-A output port.
- Matte finish shows fingerprints easily.
7. S22 Portable Charger, Mini Colorful Power Bank, 5000mah
The S22 PowerNano is a pocket rocket, especially when considering it as a contender for the best and cheapest power bank. Its mini, colorful design is definitely a visual standout, making it easy to spot in a bag. The 5000mAh capacity is enough for about one full charge on most modern smartphones, which is perfect for emergency situations.
I appreciated the compact nature of this power bank; it’s almost unnoticeable in my hand. However, the plastic casing, while colorful, feels a bit flimsy and I’d be concerned about its durability if dropped. The charging speed is adequate for its capacity, but don’t expect lightning-fast top-ups.
This is the power bank for someone who prioritizes portability and aesthetics above all else. It’s perfect for a quick emergency charge when you’re out for a short time. If you need to keep multiple devices alive throughout a long day or require rapid charging, you should look elsewhere, as this is best suited for minimal power needs.

8. Gensrock 2 Pack Portable Charger Power Bank 10000mah, Pd 22.5w
Getting two 10000mAh power banks for one price point is a compelling proposition, and the GENSROCK offering delivers on that value. The inclusion of PD 22.5W charging is a welcome feature, offering faster charging speeds than many older models. In our testing, these charged my devices noticeably quicker than expected for their price.
The units themselves feel reasonably well-built, with a textured finish that provides a good grip. My only minor gripe is that the LED indicator lights are a bit too bright, which can be a distraction in a dark room. Having a second unit is fantastic for travel or for keeping one at home and one in the car.
This two-pack is excellent for couples, families, or anyone who wants a spare power bank without breaking the bank. It’s a practical choice for everyday use and travel. However, if you’re looking for a single, high-capacity power bank with advanced features like wireless charging or multiple USB-C ports, this dual-pack might not be the most streamlined solution for your specific needs.
Pros
- Excellent value with two units.
- Supports 22.5W PD charging.
- Good grip texture.
Cons
- LED indicators are quite bright.
- No additional ports beyond the standard ones.
9. Miady 2
The Miady 2 power bank offers a straightforward approach to portable charging. Its 10000mAh capacity is a sweet spot for balancing portability and power, providing multiple charges for most smartphones. The design is understated and functional, fitting easily into a backpack or messenger bag.
I found the unit to be quite lightweight for its capacity, which is a definite plus for carrying it around all day. The plastic casing feels smooth but can be a little slippery, so a case or a good grip is recommended. While it charges devices effectively, the maximum output speed isn’t the fastest on the market, so patience is key for quick boosts.
This power bank is a solid choice for students or professionals who need a reliable way to keep their primary device powered throughout the day. It’s perfect for those who value simplicity and don’t require the absolute fastest charging speeds. If you’re a power user with multiple devices or need to charge quickly, you might be better served by a model with higher wattage output.
Pros
- Good 10000mAh capacity.
- Lightweight for its size.
- Simple and functional design.
Cons
- Smooth plastic can be slippery.
- Charging speed is not the fastest.
10. 5000mah Magnetic Portable Charger, Ultra Slim Magnetic Power Bank
The magnetic attachment on this 5000mAh power bank is its standout feature, providing a truly wire-free charging experience. It snaps onto compatible devices with a satisfying click, and the slim profile means it doesn’t add excessive bulk. I found it incredibly convenient for on-the-go top-ups without fumbling with cables.
The 5000mAh capacity is sufficient for about one full charge, making it ideal for extending battery life rather than a complete recharge. The magnetic connection feels secure, but I did notice that the power bank can sometimes shift slightly if the phone is handled roughly. The power output is adequate, but don’t expect it to charge your phone at the fastest possible rate.
This power bank is perfect for iPhone users with MagSafe compatibility who want the ultimate convenience. It’s ideal for those who are frequently on the move and need a quick, hassle-free power boost. If you don’t have a MagSafe-compatible device or require the ability to charge multiple gadgets simultaneously, this specific magnetic charger is not for you.
Pros
- Convenient magnetic attachment.
- Ultra-slim and lightweight.
- Wire-free charging experience.
Cons
- Limited to 5000mAh capacity.
- Magnetic connection can shift with rough handling.
- Primarily for MagSafe compatible devices.
