Product Description

ESSAGER Mini Capsule Power Bank – The Power Bank You Will Actually Carry Every Day

At ESSAGER, we asked ourselves a simple question. Why do people own power banks but leave them at home? The answer was obvious. Most power banks are too big, too heavy, and too much hassle to carry around just in case.

So we built something completely different. The ESSAGER Mini Capsule Power Bank is so small, so light, and so convenient that you will clip it to your keys and forget about it – until you need it. And when you need it, it delivers a full 20W fast charge in the smallest package you have ever seen.

Smaller than a lipstick – we are not exaggerating

Look at the photo. The ESSAGER Mini Capsule Power Bank is genuinely smaller than most lipstick tubes and many car key fobs. It measures approximately 75 x 25 x 25 mm and weighs only about 90 to 100 grams.

To put that in perspective:

• It is shorter than a standard ballpoint pen

• It is thinner than a tube of lip balm

• It weighs less than a golf ball

• It takes up less space in your pocket than a set of house keys

• You could fit three of them in the palm of your hand

This is not a power bank you have to plan to carry. This is a power bank that lives on your keychain, in your coin pocket, or at the bottom of your smallest bag. When you need it, it is there. When you do not, you forget you are carrying it.

5000mAh – exactly one full charge

We chose 5000mAh for a very specific reason. It is the exact amount of power most people need in an emergency – one full phone charge. No more. No less.

Here is what 5000mAh gives you in the real world with the ESSAGER Mini Capsule:

For iPhone 17 users:

• Approximately 1 full charge from 0% to 100%

• Or take your phone from 20% to 100% and have power left over

For iPhone 16 users:

• Approximately 1 to 1.2 full charges

• Enough to go from dead to full with a little extra

For iPhone 15 users:

• Approximately 1.2 to 1.3 full charges

• More than a full day of backup power

For Xiaomi 14/13 users:

• Approximately 0.9 to 1 full charge (depending on model)

• Enough to get you through the evening after a long day

For Samsung S24/S25/S26 users:

• Approximately 0.8 to 1 full charge

• A full emergency backup in a tiny package

For mixed use:

• One full iPhone charge

• Or 80% of a Samsung charge plus a full AirPods charge

• Or two emergency top-ups from 30% to 80%

Two ways to charge – built-in connector AND built-in cable

The ESSAGER Mini Capsule Power Bank features something truly unique at this size. It has two ways to charge your devices.

Method 1: Built-in USB-C connector
The power bank has a folding USB-C plug built directly into its body. Flip it out, plug it directly into the bottom of your iPhone, Xiaomi, or Samsung, and charging starts immediately. No cables. No adapters. No searching. Just plug and go.

This is perfect for:

• iPhones with exposed USB-C ports (iPhone 15, 16, 17)

• Samsung and Xiaomi phones without thick cases

• Quick emergency charges when every second counts

Method 2: Built-in USB-C cable
For phones with thick cases, recessed ports, or awkward positioning, the ESSAGER Mini Capsule also includes a short built-in USB-C cable. The cable tucks into the side of the power bank and pulls out when needed. This gives you flexibility to charge any USB-C device, even if the direct plug does not fit.

This is perfect for:

• Phones in thick protective cases

• Devices with off-center or recessed USB-C ports

• Charging AirPods, earbuds, or small accessories

• When you need distance between the power bank and your phone

Having both options means you will never be stuck unable to charge. One of them will always work.

20W PD fast charging – no slow trickle charging

Just because the ESSAGER Mini Capsule is small does not mean it is slow. This little power bank delivers a full 20W of Power Delivery fast charging.

What 20W means for your devices:

• iPhone 17 – 0% to 50% in about 25 minutes

• iPhone 16 – 0% to 50% in about 25 minutes

• iPhone 15 – 0% to 50% in about 25 minutes

• Xiaomi 14 – 0% to 50% in about 25 to 30 minutes

• Samsung S25 – 0% to 50% in about 25 to 30 minutes

At 20W, your phone charges as fast as it would from most wall chargers. You are not waiting an hour for a 20% top-up. Plug in for 15 minutes and you gain hours of battery life.

Attach it to your keys and never forget it

The ESSAGER Mini Capsule features a built-in metal keychain hole. Thread it onto your key ring, clip it to a carabiner, or attach it to your bag with a lanyard. Because it is so small and light, you will barely notice it hanging there – until your phone hits 10% battery.

Think about the last time your phone died when you were out. Were you carrying a power bank? Probably not, because they are too big to carry every day. The ESSAGER Mini Capsule solves that problem completely. Put it on your keys today, and you will always have emergency power with you.

LED battery indicator – always know your status

Four small LED lights on the side of the ESSAGER Mini Capsule tell you exactly how much power remains:

• 1 light = 25% or less (time to recharge the power bank)

• 2 lights = 25% to 50%

• 3 lights = 50% to 75%

• 4 lights = 75% to 100%

Press the small button on the side, and the lights illuminate instantly. No guessing. No surprises when you need power most.

Who is the ESSAGER Mini Capsule for?

After selling tens of thousands of units worldwide, we know exactly who loves this little power bank.

This is perfect for:

iPhone 15, 16, and 17 users – Your phone has USB-C. The built-in connector plugs directly in with no cables needed. It is the most convenient emergency charger you will ever own.

Xiaomi and Samsung users – Same convenience. Plug directly into your phone, get 20W fast charging, and keep your day going.

People who never carry a power bank because they are too big – Finally, a power bank small enough to live on your keychain. You will actually have it when you need it.

Commuters – Train, bus, or subway got delayed? Your phone is dying? Pull the ESSAGER Mini Capsule off your keys and plug in. You arrive home with battery to spare.

Night out – Going to dinner, drinks, or a concert? You do not want to carry a bag. The Mini Capsule on your keychain gives you emergency power without the bulk.

Travelers – Keep it in your personal item or carry-on. When your phone dies at the airport gate, you are covered.

Students – Between classes, the library, and the cafeteria, outlets are never convenient. Keep this on your backpack and charge anywhere.

Parents – Your phone is your lifeline for school calls, schedules, and emergencies. Dead battery is not an option. The Mini Capsule gives you peace of mind.

Emergency preparedness – Keep one in your glove box, one in your desk drawer, one in your go-bag. Tiny size means you can put them everywhere.

Recharging the Mini Capsule

Recharging the ESSAGER Mini Capsule itself is simple. Use any USB-C charger:

• Plug a USB-C cable into the power bank's input port

• Connect to any USB charger (computer, wall adapter, car charger)

• The LED lights will blink to show charging progress

• Full charge takes approximately 1.5 to 2 hours with a 20W charger

When all four LED lights are solid, the Mini Capsule is fully charged and ready for another emergency.

Designed for daily durability

The ESSAGER Mini Capsule is built to live on your keychain. That means it gets knocked around. It gets dropped. It gets jingled with your keys. We designed for that.

The exterior uses tough, fire-resistant ABS plastic that resists scratches and impacts. The folding USB-C plug is reinforced at the hinge and rated for thousands of folds. The built-in cable uses durable rubber that bends without cracking. The keychain hole is reinforced with a metal insert that will not wear through.

This is not a delicate accessory. This is a tool.

Safety features you expect from ESSAGER

Every ESSAGER power bank includes comprehensive protection:

• Overcurrent protection – prevents damaging power spikes

• Overvoltage protection – shuts down if voltage exceeds safe limits

• Overheating protection – reduces charging speed or stops if temperatures rise

• Short circuit protection – instantly cuts power if a short is detected

• Smart charging chip – automatically identifies connected device and delivers optimal power

Your expensive iPhone, Xiaomi, or Samsung is completely safe charging from the ESSAGER Mini Capsule.

Airline friendly – take it anywhere

Yes. At 5000mAh (approximately 19.25Wh), the ESSAGER Mini Capsule is well under the international 100Wh limit for carry-on luggage. Take it on any flight anywhere in the world. Keep it in your carry-on bag or on your keychain. TSA and security will not blink twice at something this small.

What about cases?

The built-in USB-C connector works best with:

• Naked phones (no case)

• Thin cases with open USB-C ports

• Apple silicone and similar thin cases

If you have a thick, rugged case (Otterbox, LifeProof, etc.), the built-in connector may not reach the USB-C port. In that case, use the built-in cable instead. It gives you the flexibility to charge any phone regardless of case thickness.

Wide device compatibility

Phones:

• iPhone 15, 16, 17 (all models)

• Samsung Galaxy S21 through S26 (all models)
