5 Best Mini Power Banks of 2025 We've Picked
5. Tactical Power Pod - Swappable Battery Portable Charger
The Tactical Power Pod is a portable, swappable battery power system designed for adventurers, commuters, and outdoor gear enthusiasts. It uses modular 21700 lithium batteries (5,000mAh each): carry just one for daily commuting, or pack several for long camping trips — power is flexible and always ready when you need it.
It supports 22.5W two-way fast charging, providing rapid power for phones, tablets, and other USB-C devices, while also recharging itself quickly via the Type-C port.
The Tactical Power Pod’s housing is made from CNC-machined aluminum alloy reinforced with ABS, built tough for outdoor conditions. Weighing only about 115 grams and roughly ¼ the size of a smartphone, it’s ultra-portable. The tactical carabiner makes it easy to attach to backpacks, belt loops, or MOLLE systems — whether you’re hiking, climbing, or commuting, your power source is always within reach. The anti-slip grip zones and one-click battery swap design allow quick battery changes, even in the rain or while wearing gloves.
Inside, the Zhiyong SW6206 intelligent chip and gold-plated Pogo pin connectors ensure efficient, stable power transfer with 6 layers of safety protection to prevent over-voltage, short circuits, or overheating.
This Swappable Battery Portable Charger is compatible with 99% of flat-top 21700 batteries on the market. Take it with you for hiking, exploration, work trips, or daily commuting — your devices will stay powered up, anywhere, anytime.
Pros:
- Removable and swappable battery design allows flexible extension of battery life.
- Lightweight body with a carabiner clip — ready to go at any time. Super easy to attach to a backpack, belt loop, or vest pocket.
- Supports 22.5W fast charging, and actual charging speed performs well.
- Clean, tactical-style design with a cool vibe — looks impressive when clipped on.
Cons:
- The battery latch design lacks clear guidance - it took quite a while to figure out how to open the battery compartment the first time.
- Battery conversion efficiency isn’t very high — a single 5,000mAh battery can barely fully charge a smartphone once.
Verdict
This Tactical Power Pod is undoubtedly more versatile and fun than traditional fixed-capacity power banks. It’s ideal for frequent hikers, campers, cyclists, photographers, outdoor adventurers, or anyone who just prefers to travel light. If future versions can improve the battery conversion rate and add clearer latch guidance, it’ll be even closer to perfect.
4. Flow Mini 2 Power Bank
Flow Mini 2 is a highly efficient charging solution that’s even smaller than a roll of film — compact enough to slip into your pocket or bag without any burden. It’s designed for frequent travelers, commuters, or busy modern users who want to keep their phone powered up at all times without carrying extra cables or bulky chargers.
Flow Mini 2 delivers up to 22.5W of maximum output (including PD 20W for iPhone), making it perfect for quickly topping up an iPhone 16/15/14, Samsung Galaxy, Google Pixel, or any other USB-C device. Its built-in intelligent temperature control chip ensures safe and efficient charging, so you never have to worry about your devices overheating.
This mini power bank comes with integrated Lightning and USB-C connectors, ready to plug in anytime — no more rummaging through your bag for tangled cables. Whether it’s for daily commuting, your travel backpack, or an emergency backup, Flow Mini 2 is the pocket-sized companion you can always count on.
Pros:
- Ultra-compact & lightweight, about the size of a large lipstick.
- Fast charging speed — boosts phone battery by 30–60% in a short time.
- Built-in Lightning and USB-C connectors, no extra cables needed.
- Solid build and high-end look & feel.
- Reasonably priced compared to similar small-capacity premium power banks.
Cons:
- Only 5,000mAh — usually not enough to fully charge large-battery devices, best for quick top-ups.
- Looks a bit awkward when plugged directly into the phone — sticks out noticeably.
- If your phone has a thick case (like an Otterbox), the main connector may not fit — only the side cable can be used.
Verdict
Flow Mini 2 is a uniquely designed, ultra-portable mini power bank — while its form factor can look a bit “quirky” when plugged in, it’s an excellent emergency backup or quick travel charger for topping up on the go.
3. SEANCHEER P05 Multifunctional Portable Power Bank
The SEANCHEER P05 is an ultra-compact 10,000mAh portable charger that perfectly combines high capacity and multifunctionality in a palm-sized device. It easily fits in your pocket, truly designed for travelers, commuters, or anyone tired of carrying multiple chargers and cables.
The P05 features a smart all-in-one design, combining a foldable wall plug (which lets you charge the power bank directly from any outlet), magnetic wireless charging, and a built-in 2-in-1 cable (one end with a USB-C connector, the other with a Lightning connector) to keep things simple. Just snap it onto an iPhone for 15W magnetic wireless charging, or use the Lightning, USB-C, and USB-A ports to charge up to three devices simultaneously (supports 22.5W fast charging). The 2-in-1 cable also doubles as a wrist strap or lanyard.
Measuring just 3.5 × 2.5 × 1.1 inches (8.9 × 5.1 × 2.8 cm) and weighing only about 224 grams (7.9 oz), the P05 slips easily into any pocket or bag. Whether you’re on a business trip, vacation, or outdoor adventure, this power bank keeps you powered up and traveling light.
Pros:
- All-in-one design (wall plug + wireless charging + 2-in-1 charging cable) makes it convenient and hassle-free.
- The 2-in-1 charging cable also doubles as a lanyard for the power bank — a clever design.
- Compact size with a large capacity (10,000mAh).
- Comes with a foldable stand for easy use.
- Supports magnetic wireless charging.
- Small enough to easily fit in a pocket or backpack.
Cons:
- The casing feels plasticky and doesn’t have the premium build quality of some higher-end brands.
- Unlike Apple’s official MagSafe, you have to press the power button manually to start charging after it magnetically attaches.
Verdict
Although the SEANCHEER P05 still has room for improvement in material quality, its design is very thoughtful — combining a foldable wall plug, a 2-in-1 charging cable/lanyard (Lightning + USB-C), magnetic wireless charging, and a 10,000mAh capacity in one device. It’s definitely worth a try!
2. Baseus PicoGo 5000mAh Ultra-Mini Magnetic Power Bank
The Baseus PicoGo is claimed to be the smallest Qi2-certified 5,000mAh magnetic power bank on the market, designed specifically for iPhone users who prioritize both portability and performance. Smaller than a credit card and weighing just 0.3 pounds, it easily slips into your pocket, wallet, or everyday carry bag, making it the perfect companion for iPhone 12 through iPhone 16 series—with zero bulk.

Its exterior features a durable aluminum alloy shell with a fingerprint-resistant nano-silicone coating, and a 5D ergonomic curved design that conforms naturally to the back of your iPhone for a secure, comfortable grip. Even smaller models like the iPhone 13 mini fit seamlessly without awkward overhang.
What really sets it apart is the built-in aluminum kickstand, which lets you go hands-free in both landscape and portrait modes—perfect for binge-watching, video calls, or scrolling TikTok while charging. The 11N strong magnetic force keeps it firmly attached to the back of your iPhone, even when using a MagSafe case.
Pros:
- Smaller than a credit card and weighs only about 0.3 lbs — easily fits in your pocket.
- Perfectly compatible with MagSafe, with strong magnetic attachment and auto-alignment — no manual adjustment needed.
- Supports dual fast charging (wireless and USB-C).
- Built-in foldable kickstand.
- Premium build quality and materials.
