❓ Frequently Asked Questions
What is MagSafe compatibility and how does the magnetic attachment work?
MagSafe is Apple's magnetic alignment and attachment system introduced with iPhone 12 in 2020. The Baseus EnerFill FM11 features a ring of powerful magnets that align perfectly with the MagSafe magnet array built into iPhone 12, 13, 14, 15, and 16 series devices. When you place the power bank against the back of a compatible iPhone, the magnets automatically snap into perfect alignment, ensuring optimal wireless charging coil positioning for maximum efficiency. The magnetic hold is strong enough to keep the power bank securely attached during normal use like walking, light movement, and holding your phone, but can still be easily removed when needed by sliding or pulling. This magnetic attachment means you can continue using your phone normally while charging without cables dangling or having to set your phone down on a charging pad. For iPhones without built-in MagSafe (iPhone 11 and earlier), you can add a MagSafe-compatible case with built-in magnets to enable magnetic attachment functionality. The power bank will still charge these older iPhones via standard Qi wireless charging, but without the magnetic snap-on convenience unless a magnetic case is used.
How many times can I charge my phone with the 10,000mAh battery?
The number of full charges depends on your phone's battery capacity and the charging method used. With 10,000mAh capacity, the Baseus EnerFill FM11 can typically provide approximately two full charges for an iPhone 14 Pro (3,200mAh battery), around 1.8 full charges for an iPhone 15 Pro Max (4,422mAh battery), approximately 1.5 full charges for Samsung Galaxy S23 Ultra (5,000mAh battery), and roughly 1.7 full charges for Google Pixel 8 Pro (5,050mAh battery). These estimates are based on USB-C wired charging which is more efficient than wireless charging. When using wireless charging, expect approximately fifteen to twenty percent lower efficiency due to energy lost as heat during the wireless power transfer process, meaning slightly fewer total charges compared to wired charging. Real-world results may vary based on factors including your phone's current battery health, background apps running during charging, screen-on usage while charging, temperature conditions, and whether you're charging from completely empty or topping up from fifty percent. For maximum charges per power bank cycle, use wired USB-C charging rather than wireless when possible.
Can I charge two devices at the same time with this power bank?
Yes, the Baseus EnerFill FM11 supports dual simultaneous charging, allowing you to charge two devices at once using different charging methods. You can charge one device wirelessly via the magnetic or Qi wireless charging surface while simultaneously charging another device via the USB-C wired output port. This is particularly useful when you need to charge your phone wirelessly while also topping up your AirPods, smartwatch, or a friend's phone via cable. When using both outputs simultaneously, the total combined output is rated at 5V/3A (15W total) which is distributed between both charging devices. This means each device receives less power than it would when charging alone: the wireless output may drop to 7.5W or 5W while the wired output operates at reduced speed compared to its maximum 22.5W capability when used independently. For fastest charging speeds, use one output at a time. However, the simultaneous charging feature is extremely convenient for situations where you need to top up multiple devices during a commute, meeting, or travel, even if individual charging speeds are somewhat reduced compared to single-device charging.
Is this power bank allowed on airplanes and safe for travel?
Yes, the Baseus EnerFill FM11 is airline-approved for carry-on luggage on virtually all commercial airlines worldwide. Aviation authorities including the International Air Transport Association (IATA), FAA (United States), CASA (Australia), and others permit lithium-ion batteries under 100 watt-hours (Wh) in carry-on baggage. The EnerFill FM11's 10,000mAh capacity at 3.7V nominal voltage equals 37 watt-hours, which is well under the 100Wh limit. This means you can confidently pack this power bank in your carry-on bag, personal item, or even keep it in your pocket during flights without any issues at security checkpoints. However, like all lithium-ion batteries, power banks must be carried in hand luggage (carry-on) and cannot be placed in checked baggage due to fire safety regulations. The power bank should also be protected from short circuits by keeping it in a case or bag pocket where metal objects like keys or coins cannot contact the USB-C port. The compact 209g weight and slim form factor make the EnerFill FM11 an ideal travel companion that won't add significant bulk to your travel kit while providing essential backup power throughout your journey.
What safety protections does this power bank have?
The Baseus EnerFill FM11 incorporates multiple layers of safety protection to ensure secure charging for both the power bank and your connected devices. Over-heating protection monitors the internal temperature during charging and discharging operations, automatically reducing power output or temporarily pausing charging if the unit exceeds safe temperature thresholds. This prevents thermal damage to internal battery cells and connected devices. Short-circuit protection detects any abnormal current flow that could indicate a wiring fault or damaged cable, immediately cutting power to prevent damage or fire hazards. Over-current protection limits the maximum current draw to prevent excessive power delivery that could damage connected devices, even if a malfunctioning device requests more power than it should. Over-voltage protection ensures the output voltage remains within safe limits regardless of internal battery state. Over-charge protection prevents the internal battery from being charged beyond its maximum safe voltage when you're recharging the power bank itself. Over-discharge protection prevents the battery from being drained below safe minimum voltage levels, which protects long-term battery health and lifespan. These protections work automatically and invisibly in the background, providing peace of mind that your expensive smartphone is being charged safely.
How long does it take to fully recharge the power bank itself?
The Baseus EnerFill FM11 supports up to 20W input charging via its USB-C port, which allows for reasonably fast recharging of the 10,000mAh internal battery. Using a 20W or higher USB-C PD (Power Delivery) charger, you can expect a full recharge from zero to one hundred percent in approximately three to four hours. With a standard 10W USB-C charger, recharge time extends to approximately five to six hours. Using a basic 5W charger will take considerably longer, potentially eight hours or more for a complete recharge. For optimal recharging speed, we recommend using a USB-C charger rated at 20W or higher, such as Apple's 20W USB-C Power Adapter, Samsung's 25W Super Fast Charger, or any good quality USB-C PD charger from reputable brands. The included USB-C to USB-C cable supports the full 20W input rate. A helpful tip is to recharge your power bank overnight so it's ready for use the next day, or charge it during work hours at your desk. The power bank includes LED indicator lights that show the current battery level so you can monitor recharging progress and know when it's fully topped up.
Does wireless charging work through phone cases?
Yes, the Baseus EnerFill FM11 wireless charging works through most standard phone cases, but there are some important considerations to keep in mind. For MagSafe magnetic attachment, your case must either be a MagSafe-compatible case with built-in magnets, or thin enough that the phone's internal magnets can still engage with the power bank. Most official Apple MagSafe cases and third-party MagSafe-compatible cases work perfectly, maintaining both strong magnetic attachment and efficient wireless charging. For standard Qi wireless charging without magnetic attachment, the power bank can charge through most cases up to approximately 3-4mm thick made from standard materials like silicone, TPU, leather, or thin plastic. However, certain case materials and features can interfere with wireless charging. Metal cases, metal plates (often used with magnetic car mounts), thick rugged cases over 5mm, cases with built-in batteries or credit card slots, and cases with metallic decorative elements will likely block or significantly reduce wireless charging efficiency. If you experience weak magnetic attachment or slow wireless charging, try removing your case temporarily or switching to a MagSafe-compatible case designed to work with magnetic wireless chargers.
Can I use this power bank with Android phones and non-Apple devices?
Absolutely, the Baseus EnerFill FM11 is designed to be universally compatible with virtually any smartphone or portable electronic device that supports USB-C wired charging or Qi wireless charging. For Android phones, you can use the USB-C wired output at up to 22.5W to fast charge Samsung Galaxy, Google Pixel, OnePlus, Xiaomi, OPPO, Huawei, and other USB-C Android devices. The power bank supports multiple charging protocols including USB-C Power Delivery (PD), so it will negotiate the optimal charging speed with your specific device automatically. For wireless charging, any Qi-certified Android phone can charge wirelessly on this power bank at speeds up to 15W, 10W, 7.5W, or 5W depending on what your phone supports. Samsung Galaxy phones with Qi wireless charging, Google Pixel phones, and many other Android devices work perfectly. The main difference compared to iPhones is the magnetic attachment feature, which is specifically designed for Apple's MagSafe system. Most Android phones do not have built-in magnets, so the power bank will not magnetically attach to Android devices unless you add a magnetic ring sticker or use a case with built-in magnets. However, wireless charging still works normally, you just need to position the phone manually rather than relying on magnetic alignment.
What devices other than phones can I charge with this power bank?
The Baseus EnerFill FM11 can charge a wide variety of portable electronic devices beyond smartphones. Using the USB-C wired output at up to 22.5W, you can charge tablets including iPad Pro, iPad Air, iPad Mini (USB-C models), Samsung Galaxy Tab, and other USB-C tablets. The power bank works excellently with wireless earbuds like AirPods Pro, AirPods, Galaxy Buds, and other USB-C charging case earbuds. Smartwatches including Apple Watch (with appropriate adapter), Samsung Galaxy Watch, and Fitbit devices can be charged via USB-C. Gaming handhelds like Nintendo Switch, Steam Deck, and ASUS ROG Ally benefit from the 22.5W output for extended gaming sessions. E-readers like Kindle Paperwhite and Kobo devices, portable Bluetooth speakers, action cameras like GoPro, and drone batteries with USB-C charging are all compatible. For wireless charging, you can charge AirPods Pro and AirPods (2nd and 3rd generation) with wireless charging cases, Samsung Galaxy Buds, and any Qi-certified device. The power bank even works with some Qi-enabled smartwatches although charging rings designed for specific watch shapes provide better alignment. This versatility makes the EnerFill FM11 an essential travel companion for charging your entire ecosystem of portable devices from a single power source.
