Product Description

ESSAGER Thin Magnetic Wireless Power Bank – The Slimmest MagSafe Battery You Will Ever Own

At ESSAGER, we looked at every magnetic power bank on the market and saw the same problem repeated over and over. They are all too thick. They take your sleek, beautiful iPhone and turn it into a bulky, heavy brick that barely fits in your pocket. So we went back to the drawing board and created something completely different.

The ESSAGER Thin Magnetic Wireless Power Bank is the slimmest 5000mAh MagSafe battery you can buy. Period.

Thin enough to leave on all day – and we mean all day

Here is what makes our power bank genuinely different. At just a few millimeters thick – approximately 8 to 9mm – it adds almost no bulk to your iPhone whatsoever. You snap it on in the morning, and by lunchtime you have forgotten it is even there. It slides into tight jeans pockets without catching. It fits in small clutches and wristlets. It works perfectly with most MagSafe cases. And it never, ever gets in the way of your daily life.

We have customers who leave this power bank attached to their iPhones permanently. That is how thin it is.

True magnetic alignment, every single time

The ESSAGER Thin Power Bank features a precision-engineered magnet array that perfectly matches Apple's own MagSafe specifications. When you bring it close to your iPhone 17, 16, 15, or 14, it snaps into place with a satisfying and secure click.

The alignment is perfect every single time. No fiddling. No positioning. No checking to see if it is actually charging. The magnets guide the power bank to exactly the right spot automatically. This means maximum wireless charging efficiency, minimum heat generation, and zero frustration.

20W wireless charging that actually delivers

Most thin power banks charge slowly. Very slowly. They overheat, so they throttle down to 5W or 7.5W. You end up waiting hours for a partial charge.

We solved this problem with intelligent thermal management and high-efficiency components. The ESSAGER Thin Power Bank delivers a full 20W of wireless charging power consistently. Your iPhone 17 Pro goes from 0% to 50% in about 30 minutes. That is just as fast as Apple's own MagSafe Battery Pack – at a fraction of the price and in an even thinner design.

Charging speed comparison:

5000mAh – the sweet spot for one full day

We chose 5000mAh for a very specific reason. It is exactly enough power for one full iPhone charge from empty to 100%, with a small reserve left over. And crucially, this capacity allows us to make the power bank incredibly thin. No unnecessary bulk. No extra weight. No wasted space or materials.

Here is what 5000mAh gives you in the real world with the ESSAGER Thin Power Bank:

For iPhone 17 users:

• Approximately 1 full charge from 0% to 100%

• Or take your phone from 20% to 100% twice

• Or keep your phone running all day with heavy navigation, streaming, and calls

For iPhone 16 users:

• Approximately 1 to 1.2 full charges

• Enough to start your day at 100% and end at 100%

For iPhone 15 users:

• Approximately 1.2 to 1.3 full charges

• More than a full day for most users

For iPhone 14 users:

• Approximately 1.3 to 1.5 full charges

• A full day of heavy use plus evening backup

For mixed use:

• One full iPhone charge plus one full AirPods Pro charge

• One full iPhone charge plus 30% left for an Apple Watch

Snap and go – no buttons, no cables, no thinking

We designed the ESSAGER Thin Power Bank to be so simple that anyone can use it instantly. Here is the entire instruction manual:

Step 1: Snap it onto your iPhone.
Step 2: That is it. Charging starts automatically.

No power button to press. No cables to find and plug in. No settings to adjust. No apps to install. No confusing LED sequences to decode.

When you want to check how much battery the power bank has left, just tap it once. The LED indicators light up to show the remaining charge. Need to turn it off? Double tap, and it stops charging (though you almost never need to do this).

The magnets are strong enough for real life

We tested the magnetic hold extensively. The ESSAGER Thin Power Bank stays attached when you:

• Put your phone in and out of your pocket

• Text with one hand while walking

• Take photos and videos

• Hold your phone in a car mount

• Hand your phone to someone else

• Shake your phone (we tested – it stays on)

The magnets are strong enough for daily use but not so strong that you struggle to remove the power bank. A gentle pull separates it easily when you are done. It is the perfect balance.

Also works as a wired power bank – true versatility

While the ESSAGER Thin Power Bank excels at wireless MagSafe charging, we included a USB-C port for situations where wireless is not ideal. Use the USB-C port to:

• Charge your AirPods – Place your AirPods wireless charging case on top of the power bank, or plug them into the USB-C port

• Charge your Apple Watch – Connect a magnetic Apple Watch puck to the USB-C port

• Charge an Android phone – Your friend with a Samsung or Pixel can still get power, even without MagSafe

• Charge any USB-C device – Earbuds, speakers, cameras, portable gaming devices, and more

• Recharge the power bank itself – Plug a USB-C cable into the port and connect to any charger

Pass-through charging – wake up to everything at 100%

Here is a feature our customers absolutely love. You can plug a USB-C cable into the ESSAGER Thin Power Bank while it is magnetically attached to your iPhone, and it will charge both devices simultaneously.

How to use it:

• Place the power bank on your iPhone before bed

• Plug a USB-C cable into the power bank

• Connect the other end to any USB-C charger

• In the morning, your iPhone is at 100% and your power bank is at 100%

This is perfect for overnight charging, desk charging, or using in the car with a USB port. No need to remove the power bank. No need to charge devices separately.

Perfect for your specific iPhone model

The ESSAGER Thin Magnetic Power Bank is optimized for every MagSafe iPhone, but each model has slightly different characteristics:

iPhone 17 Series (all models)
Perfect compatibility. The magnet array aligns flawlessly. The 20W charging speed is fully utilized. Expect a full charge from the 5000mAh battery.

iPhone 16 Series (all models)
Perfect compatibility. Same great magnetic hold. Slightly better battery efficiency means you may get a little more than one full charge.

iPhone 15 Series (all models)
Perfect compatibility. The ESSAGER Thin Power Bank works identically to the 16 and 17 series. No compromises.

iPhone 14 Series (all models)
Full compatibility. The magnet array matches perfectly. Charging speed is limited to approximately 15W by the iPhone 14 hardware, but that is still very fast.

iPhone 13 and 12 Series
Compatible, but please note: The original iPhone 12 and 13 MagSafe magnets are slightly weaker than newer models. The power bank will still attach securely, but it may be easier to knock off. Charging speed is limited to approximately 12W to 15W.

What about cases?

The ESSAGER Thin Power Bank works perfectly with:

• Apple original MagSafe cases (all colors, all materials)

• Most third-party MagSafe-compatible cases (Spigen, Otterbox, Case-Mate, Casetify, etc.)

• Thin non-Magnetic cases (the magnets still work, but hold may be weaker)

The power bank may NOT work well with:

• Very thick rugged cases (over 3mm thick)

• Cases with metal plates, rings, or card holders built in

• Cases with large bumps, ridges, or irregular surfaces

For best results, we recommend using a genuine MagSafe case or using the power bank directly on your naked iPhone.

Ultra-lightweight – you will forget you are carrying it

Weight: approximately 115 to 130 grams. That is less than a deck of cards. Less than a full coffee mug. Less than most sunglasses cases.

When you snap the ESSAGER Thin Power Bank onto your iPhone, the combined weight is still less than many other phones on the market by themselves. You will genuinely forget it is there until you look at your battery percentage and realize you are still at 98% at 5 PM.

Who is this power bank for?

The ESSAGER Thin Magnetic Wireless Power Bank is not for everyone. But for the people it is designed for, it is absolutely perfect.

This is for you if:

• You hate bulky battery cases and thick power banks

• You want a MagSafe battery you can leave attached all day

• You charge your iPhone wirelessly and never want to use cables again

• You need a slim backup that fits in small pockets or clutches

• You want Apple-quality MagSafe at a reasonable price

• You are tired of carrying separate power banks and cables everywhere

This is NOT for you if:

• You need multiple full charges away from outlets (choose our 20000mAh model)

• You regularly fly with only a small personal item (though this is airline friendly)

• You want to charge your iPhone and iPad simultaneously (choose our multi-device model)

• You use an extremely thick rugged case without MagSafe

Designed for daily durability

Despite its thin profile, the ESSAGER Thin Power Bank is built to last. The exterior uses premium matte-finish plastic that resists scratches, fingerprints, and minor drops. The internal battery cells are Grade A lithium-polymer from a tier-1 supplier. The charging circuitry includes thermal sensors that prevent overheating even during fast wireless charging.

Safety features you expect from ESSAGER

Every ESSAGER power bank includes comprehensive protection:

• Foreign object detection – Automatically stops charging if metal (keys, coins, etc.) is placed between the power bank and iPhone

• Overheating protection – Reduces charging speed or stops if temperatures rise too high

• Overcurrent protection – Prevents damaging power spikes

• Overvoltage protection – Shuts down if voltage exceeds safe limits

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

• Smart temperature control – Monitors both the power bank and your iPhone for safe operation

Your expensive iPhone 17, 16, 15, or 14 is completely safe charging wirelessly with the ESSAGER Thin Power Bank.

Airline friendly – take it anywhere

Yes. At 5000mAh (approximately 19.25Wh), the ESSAGER Thin Power Bank is well under the international 100Wh limit for carry-on luggage. You can take it on any commercial flight anywhere in the world. Keep it in your carry-on bag – never in checked luggage. It is so small and light that you will barely notice it in your personal item.

Charging the power bank

To recharge the ESSAGER Thin Power Bank itself, use any USB-C charger:

• With a 20W charger: approximately 1.5 hours for a full charge

• With a 10W to 15W charger: approximately 2 to 2.5 hours

• With a computer USB port: approximately 3 to 4 hours

The power bank accepts up to 20W input. The built-in LED indicators show progress as it charges. When all four lights are solid, it is fully charged and ready for another full day.

Why choose ESSAGER over Apple or other brands?

We get asked this question constantly. Here is the honest answer:

The ESSAGER Thin Power Bank gives you Apple-like quality at a fraction of the price, in an even thinner design, with a longer warranty. That is why customers choose us.

The bottom line

The ESSAGER Thin Magnetic Wireless Power Bank is the slimmest, most convenient MagSafe battery you can buy. It snaps onto your iPhone 17, 16, 15, or 14 and disappears. It charges at full 20W speed.

Stop carrying cables. Stop using thick battery cases. Stop worrying about battery anxiety.

Snap the ESSAGER Thin Power Bank onto your iPhone this morning and forget you are even carrying a backup battery. Your phone will still be running when everyone else is searching for outlets.
