FAQs Q: Why does the battery drain quickly? Is it a 20000 mAh battery? A: Our portable power bank is equipped with four high-quality batteries with a capacity of 5000 mAh each. A large capacity 20000 mAh power bank solves the battery worry problem. The new battery has not been activated yet. You can cycle the battery to discharge and recharge it 3-5 times, and the battery will regain its natural lifespan. Q: Why can't the battery reach a maximum capacity of 100 watts? A: To produce maximum power, the following conditions must be met simultaneously: 1. The device supports high-power protocols, such as laptops and fast chargers supporting PD 3.0. (Your electronic device needs to support PD 100W power) 2. Successful connection between charger and device: negotiating a 20V 5A mode via USB PD protocol. 3. Use qualified cables: cables must support a current of 5A (such as USB-C cables certified by E-Marker chips). 4. The device has a low battery and is under high load: if the laptop is charging while in use, this may trigger maximum power operation. Q: Can the battery charge my laptop? A: Certainly, our backup battery system is highly compatible and works with all USB charging devices. Q: Will a 100-watt battery cause my phone or tablet to burn out? A: Don't worry, our batteries have undergone safety tests and are equipped with smart chips to reduce voltage, ensuring effective device protection and providing you with safety and peace of mind.

It automatically adjusts output voltage and current according to the device needing charging, for automatic compatibility with different devices. The best travel partner committed to airline safety standards. Lightweight and easy to carry. The battery weighs only 424 grams, and its compact design makes it easy to carry. Q: Why can't the battery reach a maximum capacity of 100 watts? To produce maximum power, the following conditions must be met simultaneously: 1. The device supports high-power protocols, such as laptops and fast chargers supporting PD 3.0. 2. Successful connection between charger and device: negotiating a 20V 3.25A mode via USB PD protocol. 3. Use qualified cables: cables must support a current of 5A (such as USB-C cables certified by E-Marker chips). 4. The device has a low battery and is under high load: if the laptop is charging while in use, this may trigger maximum power. When the minimum power output is reached: 1. The device only supports basic charging protocols, such as old phones and headsets, operating only in 5V 2A mode. 2. Failed negotiation of the charging protocol: the device and charger cannot agree on a higher level, default output is 5V. 3. The device enters slow charging mode: when the battery is nearly full, power automatically decreases (e.g., from 5V 2A to 1A, with actual power being less). Output effect conditions: 1. Cable effects: using low-quality cables may prevent high-power mode activation (e.g., 20V output with only 2A, reducing power to 40W). 2. Temperature protection: chargers may actively reduce power in high-temperature environments. 3. Device limitations: some phones are designed to protect the battery and may limit power during long-term use (for example, the maximum PD charging power compatible with iPhone 14 is 27W. When using a 100W output power bank, the phone will only request compatible power, around 27W).
