Yes, the power bank  supports pass-through charging. However, a charger with a rated power of 20W or higher is required, and the input must be greater than output power to ensure the full load operation of the device.

Does it support pass-through charging? Why does it sometimes not work?

On the device screen, go to “Settings” > “Wi-Fi & BLE”, then press the confirm button to turn on the switch.
On the phone used to log into the app, make sure Bluetooth is enabled.

Wi-Fi Connection:
On the app homepage, tap the “+” icon in the top right corner to enter the device search page. You will be redirected to the pairing page.
Select the Wi-Fi network you want to connect to, enter the password, and tap “Next” to connect.
Once the connection is successful, the app will navigate to the device page, where a Wi-Fi icon will appear at the top of the screen.
(Note: Only 2.4GHz Wi-Fi is supported. If the connection fails, please follow the on-screen instructions to retry.)

Bluetooth Connection:
On the pairing page, tap “Set up later” at the bottom to skip Wi-Fi configuration.
You will be redirected to the device page, and a Bluetooth icon at the top will indicate a successful Bluetooth connection.
You can also tap the cloud icon in the top right corner of the device page while in Bluetooth mode to enter the Wi-Fi setup process.
Select your Wi-Fi network, enter the password, and complete the connection.

How do I connect the RAPID Pro power bank to the EcoFlow application via Wi-Fi/Bluetooth?

The app supports functions such as power monitoring, firmware upgrades, device management, theme switching, and charging strategy settings. Not connecting the power bank to the app does not affect its normal charging and discharging functions.

What are the functions of using the APP? Is it necessary to connect to the app to use it?

Yes, the product supports plug-and-play. However, as the product features are continuously being updated and improved, it is recommended to connect to the app and upgrade to the latest firmware for a better user experience.

Can it be used directly after unboxing?

Yes, according to regulations by the International Civil Aviation Organization (ICAO) and most airlines, carrying a power bank with a capacity under 100Wh is allowed. The RAPID Pro, with a capacity of 27650mAh (99.54Wh), meets this requirement and can be carried on board without concern.

Can the RAPID Pro power bank be taken on the plane?

Q1: What is the lifespan of the RAPID power bank?
Answer: The RAPID power bank can support up to 300–500 full charge cycles. Please note these are estimates, and actual lifespan may vary depending on usage frequency and other factors.
Q2: What are the optimal operating and storage temperatures for the RAPID power bank?
Charging: 0–40°C
Discharging: -10–40°C (please note that high temperatures may cause power reduction)
Storage: -20–40°C
Q3: At what altitude can the power bank be used?
Answer: High-altitude environments with low pressure and low temperature may affect the power bank’s performance and battery life. At very high altitudes (such as above 4000 meters), internal chemical reactions can be impaired due to low temperature and pressure, resulting in reduced charging efficiency or complete failure to operate. Additionally, extreme conditions may increase the risk of battery swelling or explosion. For safety and optimal performance, it is not recommended to use the power bank at altitudes above 3000 meters.
Q4: How can I extend the lifespan of the RAPID power bank?
Answer: It is recommended to recharge the portable charger at least once every three months.

Battery life and temperature FAQs

The power, voltage, current, and other information displayed in the app are reported to the cloud by the charger at specific intervals, which may lead to data discrepancies due to timing differences.

Why are the power, voltage, and current readings on the charger screen different from those in the application?

To ensure fast and stable charging and discharging performance when using the power bank, we recommend the following.
1. Choose the Right Charger:
Use a charger that supports fast charging protocols and has a high output power (such as PD 65W or 100W). Avoid using low-power chargers (such as 5V/1A).
2. Use a Good Charging Cable:
Select original or high-quality fast charging cables (such as those supporting 5A, 240W). Keep connectors clean and secure, and avoid excessively long cables.
3. Device Compatibility:
Make sure the connected devices support fast charging protocols; otherwise, fast charging will not be achieved.

How to keep the power bank charging and discharging quickly?

There are usually differences from expectations, mainly due to the following two factors:
1. Capacity conversion
Cell capacity refers to the total capacity of the cells inside the power bank.
For example, the total cell capacity of the RAPID Pro power bank is 27650 mAh.
Rated capacity refers to the actual amount of power a power bank can output under standard conditions (such as 5V/3A). For the RAPID Pro 27K, the rated capacity is 15900mAh.
The difference arises because cell capacity is a theoretical value, while rated capacity takes into account factors such as energy conversion efficiency and circuit losses. As a result, the actual usable power is lower than the cell capacity.
2. Energy conversion efficiency
When the power bank converts the voltage of the battery cell( such as 3.7 V) to the voltage required by the device( such as 5V), there will be energy loss. Usually, the efficiency is about 80%, which means that part of the power will be lost during the conversion process.
To estimate the number of the charges, use the following formula:
(Battery capacity *55%~66%) ÷Device battery capacity≈ Number of charges. For example, a 5000mAh power bank can usually provide about 1 charge for a 3000mAh device.

Why does the power bank provide less electricity than expected?

Supports pass-through charging, with the power level depending on the power requirements of the devices connected to each port.
Input supports PD3.1 protocol and is compatible with PD3.0 PPS, QC3.0, AFC, BC1.2;
Output supports PD3.1 protocol and is compatible with PD3.0 PPS, QC3.0, AFC, Apple2.4A, BC1.2, SCP, FCP, UFCS

What protocols does RAPID Pro power bank support, what is the power distribution for charging and discharging, and does it support chaging and discharging at the same time?

Compatible devices are laptops, phones, tablets, headphonees, smartwatches,
game consoles and other devices with USB-C ports such as MacBookPro/Air, iPhone,iPad, Dell XPS and Samsung Galaxy.
