Best Portable Charger for Oneplus 3: Top Picks

1. Portable Charger 35000mah Power Bank

When I first picked up this 35000mAh power bank, its heft was immediately apparent. This is a serious piece of kit designed for extended trips where power outlets are a distant dream. It feels robust, like it could survive a few bumps in a backpack.

The sheer capacity is impressive, easily capable of recharging my OnePlus 3 multiple times over. I found it charged my device at a respectable speed, though not the absolute fastest I’ve encountered. The multiple USB-A ports are a nice touch for charging other gadgets simultaneously.

One area where it falls slightly short is its bulk. This isn’t a pocket-friendly charger; it’s better suited for a larger bag or suitcase. The plastic casing, while sturdy, does attract fingerprints quite readily, making it look a bit smudged after just a few uses.

This power bank is ideal for long camping trips, extended travel without access to power, or for anyone who needs to keep multiple devices topped up for days on end. However, if you prioritize portability and a sleek design above all else, you might want to look elsewhere.

2. Orfeika Portable Phone Charger, 10000mah Portable Charger 22.5w Fast Charging

The Orfeika 10000mAh charger strikes a good balance between capacity and portability. It has a pleasant matte finish that feels good in the hand and doesn’t slip easily. The size is manageable, fitting comfortably in most pockets or small bag compartments.

I was pleased with the 22.5W fast charging capability; it significantly reduced the time it took to get my OnePlus 3 back to a usable charge level. The indicator lights clearly show the remaining battery percentage, which is always a practical feature.

While the charging speed is good, I noticed the unit can get a little warm during extended fast charging sessions, though never to a concerning degree. The included USB-C cable, while functional, feels a bit thin and I wonder about its long-term durability.

This charger is a solid choice for daily commuters or travelers who need a reliable power boost without excessive bulk. Those who absolutely need the absolute fastest charging speeds available might find it a touch slower than higher-wattage options.

3. Charmast Portable Charger with Built in Cables, Power Bank With

The charmast power bank immediately caught my eye with its integrated cables. This is a fantastic feature for anyone tired of forgetting or tangling with separate cords. The unit feels solid, with a textured grip that prevents accidental drops. It’s a practical solution for finding the best portable charger for oneplus 3 on the go.

Charging my OnePlus 3 was straightforward, with the built-in cables ensuring a quick connection. The capacity is sufficient for a couple of full charges, making it ideal for a day out or a short trip. The convenience of not needing extra cables is a significant advantage.

However, the built-in cables are fixed, meaning if one were to become damaged, the entire unit might be compromised. I also found the indicator lights to be a bit too bright, which can be a minor annoyance in a dark room. The charging speed, while adequate, isn’t the absolute fastest available.

This charger is perfect for the minimalist traveler or someone who values extreme convenience and hates carrying extra accessories. If you anticipate needing to replace or upgrade cables frequently, or require bleeding-edge charging speeds, this might not be your ideal pick.

4. Iniu 45w Fast Charging Portable Charger, 40% Smaller 10000mah With

The INIU 45W charger is impressively compact for its power output. It genuinely feels much smaller than other 10000mAh options I’ve tested, making it incredibly easy to slip into a pocket. The matte black finish is sleek and resists smudges well.

I was really impressed with the 45W fast charging; it juiced up my OnePlus 3 incredibly quickly, bringing it back to life in a remarkably short time. The build quality feels premium, with solid buttons and a reassuring weight that doesn’t feel cheap.

While the compact size is a huge plus, I did find that the single USB-C port, while capable of high wattage, means you can’t charge multiple devices at maximum speed simultaneously. The textured surface, while good for grip, can also trap dust in its crevices over time.

This INIU charger is an excellent choice for power users who demand fast charging and ultimate portability. If you frequently need to charge multiple devices at once at high speeds, you might need to consider a larger capacity or multi-port unit.

5. Iniu Portable Charger, Ultra Mini 10000mah 45w Fast Charging With

This INIU charger lives up to its ‘Ultra Mini’ moniker. It’s astonishingly small and lightweight, easily the most pocketable 10000mAh charger I’ve handled. The smooth, slightly rubberized finish feels secure in hand and doesn’t slide around.

The 45W fast charging is a standout feature here, delivering rapid power to my OnePlus 3 and significantly reducing downtime. The build feels robust despite its small size, and the LED display for battery percentage is a clear and useful addition.

My only real quibble is that the small form factor means it can get noticeably warm during prolonged high-wattage charging, though never to an alarming temperature. Also, the single USB-C port, while powerful, means you’re limited to charging one device at a time if you want to take full advantage of the 45W speed.

This is the perfect power bank for those who prioritize absolute portability and fast charging above all else. If you regularly need to charge multiple devices simultaneously at high speeds, or prefer a larger capacity for extended trips, this might be a bit too small for your needs.

This power bank is ideal for extended trips or for users who constantly find themselves away from power outlets for days at a time. If you’re a photographer on location or a student pulling all-nighters in the library, this will be your best friend. However, its substantial bulk means it’s not something you’ll casually slip into a pocket; it’s designed for a backpack or a larger bag.

7. Portable Charger Power Bank 25800mah,5v/3a Fast Charging Portable Phone Charger,3

This 25800mAh power bank strikes a good balance between capacity and portability. It feels solid in the hand, with a smooth, slightly glossy finish that does tend to attract fingerprints.

The single built-in cable is a nice touch, reducing clutter.

This is a fantastic option for anyone who prioritizes convenience and speed in a portable charger. If you hate carrying extra cables and need a quick power boost, this is a great fit. However, those who need to charge multiple devices simultaneously or require an extremely high capacity for multi-day trips might find its capacity a bit limiting.

9. Portable Charger Power Bank 40800mah with 3 Built

This 40800mAh power bank is a serious contender for those who need serious power. Its size is substantial, and it has a reassuring heft to it, suggesting a robust internal battery.

The unit feels robust and durable, giving me confidence that it can handle the rigors of travel. The integrated cables feel securely attached.

This power bank is ideal for long trips, camping, or for users who have multiple power-hungry devices to keep charged. If you prioritize sheer capacity and fast charging, this is a compelling option. However, its considerable size and weight mean it’s not for those seeking a lightweight, ultra-portable solution; it’s definitely a bag item.
