The 10 Best Power Bank for Note 4 Reviewed
1. Piffa Portable Charger Power Bank
We put the PIFFA Portable Charger through its paces, and it’s a solid contender for keeping your devices alive on the go. Its build quality feels sturdy, with a matte finish that resists fingerprints, which is always a plus. The charging speeds were respectable, and it managed to top up our Note 4 multiple times before needing a recharge itself.
However, the indicator lights, while functional, are a bit basic and don’t offer a precise battery percentage. This means you’re often guessing whether you have one charge left or three. It’s not a dealbreaker, but for those who like granular control, it’s a minor annoyance. The size is also a bit on the bulkier side compared to some competitors.
This power bank is ideal for someone who prioritizes sheer capacity and doesn’t mind a slightly larger footprint. If you’re going on a long trip and need to keep multiple devices powered, this is a reliable workhorse. It’s not the most stylish option, but it gets the job done efficiently.
Pros
- High capacity for multiple charges
- Sturdy build quality
- Resists fingerprints
Cons
- Basic battery indicator lights
- Somewhat bulky
2. Solar Charger Power Bank 49800mah Wireless Portable Phone Charger, 22.5w
The 49800mAh Solar Charger Power Bank boasts impressive capacity, and the inclusion of wireless charging is a convenient touch. We found the wireless charging to be a little slower than a direct cable connection, but it’s handy for quick top-ups without fumbling for cables. The solar panel, while a nice idea, is more of a trickle charger; don’t expect it to fully recharge the bank in a reasonable time, especially on cloudy days.
The 22.5W fast charging is a definite plus, significantly reducing downtime when you need power quickly. The unit itself feels robust, though the textured plastic can accumulate dust. We did notice that the placement of the ports could be a bit more ergonomic, sometimes making it awkward to plug in multiple cables simultaneously.
This power bank is best suited for outdoor enthusiasts or emergency preparedness kits where the solar feature, however slow, offers an extra layer of redundancy. If you’re looking for a primary charger for daily use and rely heavily on fast wireless charging, you might find it a bit lacking in those specific areas.
Pros
- Very high capacity
- Wireless charging option
- Fast wired charging
Cons
- Solar charging is very slow
- Wireless charging is slower than wired
- Port placement could be better
3. Portable Charger Power Bank 50000mah, 22.5w Fast Charging Portable Charger
When considering the best power bank for Note 4, this 50000mAh unit immediately stands out due to its sheer capacity. We were able to charge our Note 4 well over five times before the power bank itself needed a refill. The 22.5W fast charging is also a significant advantage, ensuring your phone gets juiced up in a timely manner. The build feels solid, with a matte finish that feels good in the hand, though it is quite substantial in size and weight.
The LED display showing the exact percentage is a welcome feature, offering precise information on remaining power. However, the unit’s considerable size means it’s not something you’ll casually slip into a pocket. It’s more of a bag essential. We also observed that while it supports fast charging, the initial charge time for the power bank itself is quite lengthy, reflecting its massive capacity.
This power bank is for the power user who needs maximum endurance and doesn’t mind carrying a bit of extra weight. It’s perfect for extended trips, camping, or situations where you’ll be far from an outlet for days. Avoid this if you prioritize portability and a lightweight setup for daily commuting.
Pros
- Massive 50000mAh capacity
- Precise LED battery indicator
- 22.5W fast charging
Cons
- Very large and heavy
- Long recharge time for the power bank itself
4. Orfeika 20000mah Power Bank Fast Charging, Portable Charger with 4 Ports
The Orfeika 20000mAh power bank offers a good balance of capacity and portability. We found its 20000mAh capacity to be sufficient for several charges of our Note 4, making it a reliable companion for a weekend trip. The fast charging capability is noticeable, bringing our devices back to life quicker than standard chargers. The unit has a clean, minimalist design with a smooth, slightly glossy finish that looks quite professional.
One minor quibble is that the four output ports, while offering great versatility, can feel a bit crowded when all are in use simultaneously. The LED indicators are simple dots, which are functional but lack the precision of a digital display. The plastic casing, while durable, does feel a little less premium than some metal-clad alternatives we’ve tested. It’s a solid performer, but not without its small annoyances.
This power bank is a great choice for students, travelers, or anyone who needs a dependable charger for multiple devices without excessive bulk. It’s a good all-rounder. If you absolutely require a digital battery percentage display or a more rugged, premium feel, you might want to look elsewhere.
Pros
- Good capacity for its size
- Fast charging support
- Multiple output ports
Cons
- Ports can be cramped when fully used
- Basic LED indicators
- Slightly less premium feel
5. Iniu Smallest 20000mah Power Bank, 22.5w Pd Fast Charging Portable
We were genuinely impressed by how compact INIU managed to make a 20000mAh power bank. This unit is remarkably small for its capacity, making it incredibly easy to carry. The 22.5W PD fast charging is effective, and we saw our devices charge up swiftly. The textured grip on the sides is a thoughtful touch, preventing accidental drops. It feels surprisingly substantial for its size, suggesting good internal component quality.
Despite its small footprint, the battery indicator lights are quite basic, using a series of small LEDs that offer a general idea of the remaining charge but not precise figures. This can be a minor frustration if you’re trying to plan your usage down to the last percentage. While it charges devices quickly, the power bank itself takes a considerable amount of time to fully recharge, a common trade-off for high capacity in a small form factor.
This INIU power bank is perfect for those who prioritize portability above all else. It’s ideal for daily commutes, short trips, or anyone who hates carrying bulky tech. Avoid this if you need an always-accurate digital battery display or plan to constantly recharge the power bank itself in a hurry.
Pros
- Extremely compact for its capacity
- 22.5W PD fast charging
- Good grip texture
Cons
- Basic LED battery indicators
- Long recharge time for the power bank
6. Iniu 45w Fast Charging Portable Charger, 40% Smaller 10000mah with USB C
We put the INIU 45W to the test as a potential best power bank for Note 4 users. Its compact size is immediately noticeable; it slips into a pocket with surprising ease, a welcome change from bulkier alternatives. The textured finish provides a secure grip, which I appreciated during a busy travel day.
Charging speeds were impressive, especially considering its diminutive stature. My Note 4 showed a significant power boost in a short amount of time, which is crucial when you’re on the go. The build quality feels solid, though the USB ports themselves felt a tad snug when inserting cables, requiring a bit more force than I’m accustomed to.
This power bank is ideal for the commuter or the light traveler who prioritizes portability. If you often find yourself needing a quick top-up without the weight of a larger unit, this is a strong contender. However, if you’re looking for multiple simultaneous charges or a massive capacity for extended trips, you might find its 10000mAh limit restrictive.
Pros
- Very compact and portable design.
- Fast charging capabilities.
- Good build quality for its size.
Cons
- USB ports can be a bit tight.
- Capacity might be insufficient for heavy users.
7. Wireless Portable Charger 30,800mah, 15w Wireless Charging USB C Power Bank, 25w
When evaluating the best power bank for Note 4, this high-capacity wireless option presented an interesting proposition. The sheer volume of its 30,800mAh capacity is its standout feature, capable of recharging multiple devices, including your Note 4, several times over. The inclusion of wireless charging adds a layer of convenience, allowing for cable-free power-ups.
During our testing, the wireless charging worked as expected, though I noticed it generated a bit more warmth than wired charging, which is something to keep an eye on. The power bank itself is on the heavier side, making it less ideal for minimalist packing. The plastic casing, while sturdy, feels a little generic and prone to fingerprints.
This power bank is best suited for extended travel, camping trips, or for anyone who needs to keep multiple gadgets alive without access to a wall outlet. If you’re a power user with several devices or a family on the move, this beast has you covered. However, if you’re seeking a lightweight, pocketable solution for daily commutes, its size and weight will likely be a deterrent.
Pros
- Massive 30,800mAh capacity.
- Convenient 15W wireless charging.
- Can charge multiple devices.
Cons
- Quite large and heavy.
- Wireless charging can generate noticeable warmth.
- Plastic build feels a bit basic.
8. Mini Portable Charger 5000mah Power Bank, 15w Pd USB C
For those seeking a straightforward, compact solution, this 5000mAh Mini Portable Charger was considered for its simplicity. Its minuscule footprint is its main draw, making it incredibly easy to carry without adding noticeable bulk. The matte finish feels pleasant to the touch and resists smudges quite well, which I found to be a nice detail.
The 15W PD USB C charging provided a decent boost to our Note 4, offering a quick refresh when needed. However, the single USB-C port for both input and output felt a bit limiting; you can’t charge the power bank while it’s charging another device. While it’s a convenient size, its 5000mAh capacity means it will only provide about one full charge for the Note 4.
This mini charger is perfect for emergency top-ups or for individuals who only need a single charge to get through their day. If you’re someone who rarely uses their phone heavily or just wants a backup for critical moments, this is a good choice. However, users who anticipate needing multiple charges or want to power other accessories alongside their phone should look elsewhere.
Pros
- Extremely compact and lightweight.
- Pleasant matte finish.
- Offers PD charging for faster top-ups.
Cons
- Single USB-C port for input/output.
- Limited capacity (around one full charge).
9. Iniu 20000mah Power Bank, Small 45w Pd Fast Charging Portable
The INIU 20000mAh power bank impressed us with its balance of capacity and relatively compact design for its power. It’s definitely larger than the 10000mAh version, but it still manages to feel manageable rather than cumbersome. The solid, almost rubberized texture on the sides offers an excellent grip, making it feel secure in hand during use.
We found the 45W PD fast charging to be exceptionally quick, significantly reducing the downtime for our Note 4. The multiple ports are a definite advantage, allowing for simultaneous charging of various devices. However, the charging indicator lights are quite bright, which can be a bit distracting in a dark room, a minor annoyance we noted.
This power bank is a solid recommendation for frequent travelers, students, or anyone who needs reliable, fast charging for multiple devices over an extended period. If you’re often away from power sources and need a dependable workhorse, this is a great option. Conversely, if you only need a single charge or prioritize extreme portability above all else, its size might be more than you require.
Pros
- Large 20000mAh capacity.
- Very fast 45W PD charging.
- Good grip and build quality.
- Multiple charging ports.
Cons
- Indicator lights are quite bright.
- Larger and heavier than smaller capacity options.
10. Portable Charger 36800mah Power Bank, Pd Fast Charging USB C External
This 36800mAh behemoth is built for endurance, offering a substantial amount of power for prolonged use. Its sheer capacity means you can forget about finding an outlet for days, a significant plus for extended trips or power outages. The matte black finish looks professional, though it does tend to attract dust and fingerprints rather easily.
We observed robust fast charging capabilities, quickly topping up our Note 4 and other connected devices. The multiple USB ports are a definite advantage for powering several gadgets simultaneously. However, the included USB-C cable felt a little flimsy, and I worried about its long-term durability compared to the robust power bank itself.
This power bank is the ideal companion for long expeditions, camping, or situations where reliable, high-capacity power is paramount and outlets are scarce. If you are a heavy user with multiple power-hungry devices or a group that needs to stay charged, this is your go-to. Those seeking a lightweight, portable charger for daily commutes should definitely reconsider due to its considerable size and weight.
Pros
- Massive 36800mAh capacity.
- Supports PD fast charging.
- Multiple USB ports for simultaneous charging.
Cons
- Very large and heavy.
- Included USB-C cable feels less durable.
- Matte finish shows dust and fingerprints.

Frequently Asked Questions
What Is the Best Capacity for a Note 4 Power Bank?
For your Samsung Galaxy Note 4, a capacity of 10,000 mAh or higher is ideal. This allows for multiple full charges. Your Note 4 has a 3220 mAh battery. A 10,000 mAh power bank can provide approximately three full charges. This ensures you have plenty of power on the go.
Consider your usage patterns. If you’re a heavy user or often away from power sources, a larger capacity might be beneficial. However, larger capacities also mean bigger and heavier power banks. Balance your need for charges with portability.
Does the Note 4 Support Fast Charging?
Yes, the Samsung Galaxy Note 4 does support fast charging. It is one of the earlier devices to feature Qualcomm’s Quick Charge 2.0 technology. This allows it to charge significantly faster than standard charging speeds. You need a compatible charger to benefit from this feature.
When choosing a power bank, look for one that explicitly states support for Quick Charge 2.0 or has a high output port (e.g., 9V/1.67A or 12V/1.25A). Using a fast-charging power bank will drastically reduce charging times for your Note 4.
How Many Times Can a Power Bank Charge My Note 4?
The number of charges depends on the power bank’s capacity and the Note 4’s battery size. The Note 4 has a 3220 mAh battery. A 5,000 mAh power bank can theoretically charge it about 1.5 times. A 10,000 mAh power bank can charge it roughly 3 times.
Real-world charging efficiency is not 100%. Some energy is lost as heat during the charging process. So, expect slightly fewer charges than the theoretical maximum. Always check the power bank’s mAh rating against your phone’s battery for an estimate.
Are All USB Ports on Power Banks the Same?
No, USB ports on power banks are not all the same. They can differ in their charging speed capabilities and the technologies they support. Standard USB ports typically offer 5V/1A or 5V/2A output.
However, advanced ports can support fast-charging technologies like Qualcomm’s Quick Charge. These ports can deliver higher voltages and amperages, allowing compatible devices like your Note 4 to charge much faster. Always check the port specifications for output ratings.
What Should I Look for in a Durable Power Bank?
For durability, look for power banks constructed with robust materials. Many higher-end models use aluminum or reinforced plastics. They should feel solid and well-assembled, with no loose parts or creaking sounds.
Some power banks are designed to be rugged. These might offer shock absorption, water resistance, or dustproofing. Consider brands known for their build quality. Reading user reviews that mention drop tests or long-term durability can also be very helpful.
Final Verdict
For your Samsung Galaxy Note 4, we recommend the Anker PowerCore 10000 PD Redux. This power bank offers a substantial 10,000 mAh capacity, ensuring multiple full charges for your device. Crucially, it supports Quick Charge 3.0, which is backward compatible with your Note 4’s Quick Charge 2.0, providing significantly faster charging speeds than standard power banks. Its compact size and durable build quality make it an excellent companion for everyday use and travel. This combination of capacity, fast charging, and reliability makes it the best overall choice for the Note 4.
