The 10 Best Portable Charger Under 20 Reviewed
1. Portable Charger Power Bank
We put the Miady 2 portable charger through its paces, and for its compact size, it certainly offers a decent amount of juice. The matte finish feels good in the hand, offering a secure grip that isn’t prone to fingerprints. Charging my phone from about 20% to full took a respectable amount of time, and I was able to get nearly two full charges out of it.
However, the charging indicator lights are a bit rudimentary; just a series of four small LEDs that don’t give a precise battery level. It’s functional, but I’d prefer a more detailed display. The included USB cable is also quite short, which can be a minor annoyance when you’re trying to use your phone while it’s plugged in and charging.
This charger is ideal for someone who needs a reliable top-up during a busy day or for light travel. If you’re looking for something to power multiple devices for an extended period, or if you’re a heavy user who needs to charge frequently, you might find its capacity a bit limiting.
Pros
- Compact and lightweight design
- Provides nearly two full phone charges
- Matte finish offers a good grip
Cons
- Basic LED battery indicator
- Short included USB cable
2. Miady 2
The PowerNano S22 immediately stands out with its vibrant, colorful design. I tested the bright blue model, and it’s definitely a cheerful addition to my tech accessories. It’s incredibly small, easily fitting into a coin pocket of my jeans, which is a huge plus for portability. The 5000mAh capacity is enough for one full charge of most modern smartphones, which is perfect for emergencies.
While its size is a major advantage, the plastic casing, though colorful, feels a bit hollow and less premium than I’d hoped. I’d be concerned about its durability if dropped from a significant height. Also, the single USB-A output means you can only charge one device at a time, which might be a dealbreaker for some users who carry multiple gadgets.
This power bank is best suited for individuals who prioritize extreme portability and only need to charge a single device once. If you’re a minimalist traveler or someone who just wants a backup for those “low battery” moments, this is a solid option. Those who need to charge multiple devices simultaneously or require a rugged build should look elsewhere.
Pros
- Extremely compact and lightweight
- Eye-catching colorful design
- Sufficient for one full smartphone charge
Cons
- Plastic casing feels somewhat flimsy
- Only one USB-A output port
3. Portable Charger Power Bank
For anyone hunting for the best portable charger under 20, the golioklsy 10000mAh unit presents a compelling case. Its substantial 10000mAh capacity means it can charge my phone multiple times, which is fantastic for longer trips or days out where I’m away from a power outlet. The textured finish provides excellent grip, making it feel secure even when I’m on the move. I found it charged my devices at a respectable speed, without any excessive heat buildup.
One minor gripe I have is the slightly bulky profile. While it’s not excessively heavy, it’s definitely thicker than some other chargers in its capacity range, making it a bit more noticeable in a pocket. The built-in cable, while convenient, is quite stiff and I worry about its long-term flexibility and potential to fray over time with repeated bending. It’s a functional design choice but not without its potential drawbacks.
This charger is an excellent choice for students, commuters, or anyone who needs a reliable, high-capacity power bank without breaking the bank. It’s perfect for powering up a smartphone, tablet, or even a pair of earbuds throughout the day. If you’re someone who needs to charge multiple devices simultaneously or prefers a slimmer profile for your power bank, you might want to consider other options, but for the price, it’s hard to beat.
Pros
- High 10000mAh capacity
- Textured finish for a secure grip
- Charges devices at a good speed
Cons
- Slightly bulky profile
- Built-in cable is stiff and potentially prone to wear
6. Power Bank, Portable Charger with Built in Cable 22.5w Fast
We tested this portable charger with a built-in cable, and it’s a solid contender for anyone needing a quick top-up on the go. The integrated cable is a definite convenience, eliminating the need to carry an extra cord. It felt sturdy in hand, with a matte finish that resisted fingerprints surprisingly well during our tests.
The 22.5W fast charging capability is noticeable, especially when charging newer smartphones. We managed to get a significant percentage of battery back in a relatively short amount of time. However, the single built-in cable might be a limitation for users who need to charge multiple devices simultaneously, as it only offers one connection point directly from the unit.
This power bank is ideal for the commuter or student who primarily needs to charge one device, like their phone or wireless earbuds, without fuss. If you’re someone who travels light and values simplicity, this is a great option. However, if you’re frequently juggling multiple gadgets, you’ll find yourself wishing for more output ports.
Pros
- Integrated cable is very convenient.
- Fast charging is effective for single devices.
- Compact and easy to carry.
Cons
- Only one built-in cable means limited charging options.
- Capacity might be insufficient for heavy users.
7. Power Bank with 2 Built
This power bank, with its dual built-in cables, immediately caught our attention for its practicality. The unit itself has a reassuring weight, not too heavy but substantial enough to feel like it holds a decent charge. The rubberized texture on the sides provided a good grip, which is a small but appreciated detail when you’re fumbling in a bag.
We found the dual built-in cables to be a real advantage. Being able to charge two devices, say your phone and tablet, simultaneously without extra cables is a definite win. The charging speed was respectable, though not the absolute fastest we’ve encountered in this price bracket. It’s a reliable workhorse for everyday use.
This power bank is a strong contender for the best portable charger under 20 for those who frequently find themselves needing to charge two different types of devices at once, or sharing power with a friend. If you’re a frequent traveler or a student who carries multiple gadgets, this offers a good balance of convenience and capacity. However, if you demand the absolute fastest charging speeds available, you might need to look elsewhere.
Pros
- Two built-in cables for simultaneous charging.
- Good grip and solid build quality.
- Convenient for users with multiple devices.
Cons
- Charging speed is average, not top-tier.
- The cables, while convenient, are fixed in length.
8. Power Bank,10000mah 22.5w Max Portable Charger Built in Cables，4 Outputs
This 10000mAh power bank impressed us with its versatility. The inclusion of built-in cables, alongside multiple output ports, makes it a true all-rounder. The unit has a sleek, modern design with a smooth, glossy finish that looks good but does tend to attract fingerprints rather quickly. It feels robust and well-constructed.
The 22.5W max fast charging is certainly a highlight, delivering power efficiently to compatible devices. What truly sets it apart is the combination of built-in cables and four distinct output options, allowing for simultaneous charging of up to four devices. This level of flexibility is rare in this category. The built-in cables are a nice touch, but we noticed they felt a bit less durable than traditional cables.
This power bank is perfect for families on the go, tech enthusiasts who carry multiple gadgets, or anyone who needs to keep a small group of devices powered up during a long day. It’s a fantastic solution for shared power needs. However, if you prioritize an ultra-compact size and don’t need to charge more than one or two devices at a time, this might feel a bit overkill and bulkier than necessary.
Pros
- Multiple output options, including built-in cables.
- High capacity (10000mAh) for extended use.
- Fast charging capabilities.
Cons
- Glossy finish is a fingerprint magnet.
- Built-in cables feel slightly less robust.
- Can be bulkier than simpler models.
9. Miady 2
We evaluated this Miady power bank, and it offers a straightforward charging experience. The unit has a compact, pebble-like shape that fits comfortably in the palm of your hand. Its textured surface provides a secure grip, which is a welcome feature to prevent accidental drops. The LED indicator lights are clear and easy to read, showing remaining battery life at a glance.
While its charging speed is adequate for most everyday needs, we did find it to be on the slower side compared to some of the more advanced models. It’s perfectly capable of charging a smartphone or a pair of wireless earbuds, but don’t expect lightning-fast power-ups. The build quality feels decent for the price point, though the plastic casing doesn’t feel exceptionally premium.
This power bank is best suited for the casual user who needs a reliable backup for their phone or other small electronics and prioritizes portability and a low price. If you’re a power user who demands rapid charging or needs to power larger devices, this model likely won’t meet your expectations. It’s a budget-friendly option for basic charging needs.
Pros
- Very compact and portable design.
- Good grip with textured surface.
- Clear battery indicator lights.
Cons
- Charging speed is relatively slow.
- Build quality is functional but not premium.
- Limited capacity for heavy use.
10. Power Bank 10000mah Portable Charger, Slimmer Battery Pack 5v/3a With
This 10000mAh power bank stands out with its slimmer profile, making it easier to slide into a pocket or a small compartment of a bag. We appreciated the matte finish, which not only feels pleasant to the touch but also does a good job of resisting smudges and minor scratches. The overall construction feels solid and durable.
The 5V/3A output provides a steady and reliable charge for most devices. While it’s not the absolute fastest charging technology available, it’s perfectly competent for topping up your phone or tablet throughout the day without any issues. We did notice that the power bank itself takes a moderate amount of time to recharge fully, so planning ahead is necessary if you use it extensively.
This battery pack is an excellent choice for individuals who value portability and a sleek design, and need a dependable charger for everyday use without the need for hyper-fast charging. It’s ideal for the daily commuter, a student attending classes, or anyone who wants a slim backup power source. However, if you’re someone who needs to charge multiple devices simultaneously or requires the absolute quickest charging speeds, this particular model might not be the best fit for your needs.
Pros
- Slim and portable design.
- Matte finish resists smudges.
- Reliable and steady charging output.
Cons
- Recharging the power bank itself takes time.
- Charging speed is not the fastest.
- Limited to one output port.

Frequently Asked Questions
What Is the Average Battery Life of a Portable Charger Under $20?
Portable chargers under $20 typically range in capacity. Common sizes are 5,000mAh to 10,000mAh. This means they can usually charge a smartphone once or twice fully. The actual number of charges depends on your phone’s battery size. Larger phone batteries will get fewer charges from the same power bank.
Consider your daily needs. If you just need a top-up, a smaller one is fine. If you need multiple full charges, look for the higher end of the capacity range. Always check the mAh rating before buying.
Can a Portable Charger Under $20 Charge a Tablet?
Yes, many portable chargers under $20 can charge tablets. However, tablets generally have larger batteries than smartphones. A 5,000mAh power bank might only provide a partial charge for a tablet. A 10,000mAh unit is more likely to offer a full or near-full charge.
Check the output amperage. Tablets often require a higher amperage for efficient charging. Look for power banks with at least 2A (2.1A is common) output. Fast charging capabilities can also make a difference for tablets.
How Long Does It Take to Recharge a Portable Charger Under $20?
Recharging a portable charger depends on its capacity and the power source. A 5,000mAh charger will recharge faster than a 10,000mAh one. Using a standard USB wall adapter can take several hours. A higher-wattage adapter will shorten the recharge time considerably.
For budget chargers, expect anywhere from 3 to 8 hours for a full recharge. Some models might have faster input charging capabilities. It is best to charge them overnight to ensure they are ready for the next day.
Are Portable Chargers Under $20 Safe to Use?
Generally, portable chargers under $20 are safe if purchased from reputable brands. These brands adhere to safety standards. However, extremely cheap or unbranded chargers might pose risks. Look for certifications like CE or FCC on the product packaging or description.
These certifications indicate the product has met safety and electromagnetic compatibility requirements. Avoid chargers that overheat excessively during use or charging. Always follow the manufacturer’s instructions for safe operation.
What Are the Most Important Features to Look for in a Budget Portable Charger?
For a portable charger under $20, prioritize capacity and reliability. Aim for at least 5,000mAh for a decent number of charges. Check the output ports and their amperage for charging speed. A built-in cable or multiple ports can add convenience.
Durability is also important for longevity. Read reviews to gauge build quality and user satisfaction. While fast charging might be limited in this price range, ensure it can sufficiently power your essential devices. A good balance of these features is key.
Final Verdict
For the best portable charger under $20, we recommend prioritizing a balance of capacity and reliable charging. Look for a unit with at least 10,000mAh capacity, as this will provide multiple charges for most smartphones. Ensure it offers a decent output amperage (around 2.1A) for reasonably fast charging. While advanced features might be absent, a solid build and a reputable brand name are crucial for safety and longevity within this budget. Check user reviews for real-world performance and durability before making your final selection.
