DELTA MAX MAINS AND CAR CHARGING
1.WHAT ARE THE CHARGING STANDARDS? HOW LONG DOES IT TAKE TO CHARGE MY DELTA MAX?
The DELTA MAX supports three charging methods: mains charging, car charging, and solar charging:
Mains charging
Voltage of mains charging input: AC 220-240V (50Hz/60Hz) Current: 10A
AC charging input power: X-Stream supercharge 2000W max
X-Stream supercharge charging time: 1 hour 0-80% 1.6 hours 0-100%
Charging with a car charger
Input from car charger: 12V/24V, DC 8A (maximum)
Charging time: 21 hours
Charging with a solar panel
Solar charging input 800W 11-110V DC 10A (maximum)
Charging time: 3.2-6.3 hours (400W x 2 in series); 4-8 hours (110W x 2 in series) or (160W x 2 in series)
Combined charging
DELTA MAX charges up safely and rapidly from 0-80% in just 65 minutes. And it gets even better. If you’re looking for an even faster way to charge up DELTA MAX, you can combine AC with Solar Panels to get up to 2600W accepted input power.
2. WHAT TO DO IF CHARGING POWER IS LOW?
1. If the ambient temperature is too high, turn off the machine or stop the load, and let DELTA MAX cool down for some time.
2. If the ambient temperature is too low, place DELTA MAX in a place with a higher ambient temperature or use electrical appliances to discharge for a while, to let the battery heat up before charging.
3. The charging power of the machine is related to the State of Charge of the battery. When the machine starts charging from 0% or is about to be fully charged, it is expected that the charging power is lower than during other phases of the charge cycle.
3. WHAT TO DO IF CHARGING POWER HOPS FOR A SHORT TIME?
Calibrate the unit (item 6 above) and do a complete charge and discharge cycle, then try to see if the problem reappears during charging. If it still occurs, please take a video of the fault and contact the after-sales service at [email protected].
4. DOES THE DELTA MAX SUPPORT CHARGING WHILE USING?
Yes, DELTA MAX supports charging and discharging when charging in vehicles, by solar panels, etc. However, when the battery of the machine is low or is about to run out, it is best not to connect appliances to the DELTA MAX while connected to DC charging (solar/vehicle charging); at this time, if the input of the power is less than or equal to the output power, the device will continue to consume power, which may result in power loss and eventually damage the battery.
5. IS THE SIMULTANEOUS ACCESS OF THE MAINS AND CAR CHARGER SUPPORTED?
Yes, this is called dual fast charge up to 3000W. Need to connect an Extra Battery.
6. WHAT TO DO IF THE BATTERY DOES NOT CHARGE TO 100%?
Conduct a calibration i.e. fully discharge and charge the battery.
7. IS IT POSSIBLE TO USE OTHER PRODUCTS TO CHARGE DELTA MAX?
1. In addition to the main sockets, car chargers, and solar panels can also charge DELTA MAX. You can also use equipment such as generators or inverters if they provide 220-240V (50Hz/60Hz) AC power. These should be connected to the AC port of DELTA MAX. The output is a sine wave, which can charge DELTA Max. When charging the DELTA MAX, X-Stream needs an AC input power to be greater than 2400W.
8. WHY DELTA MAX CANNOT TURN ON?
1. Check for an insufficient battery charge level. If you suspect this, charge and turn the unit on again. If the charging fails, please follow the instructions on charging failures.
2. If there is no response after you short-press or long-press the Main Power Button for 3 seconds, please contact Energian Customer Service at [email protected] or 020 8064 0335.
10. WHAT TO DO IF THE DELTA MAX DOES NOT CHARGE?
This can be caused by one of a few issues:
1. The ambient temperature is too high. The ambient temperature suitable for charging the DELTA MAX is between 0℃ and 45℃. If you have used a DELTA MAX with high-wattage appliances for a long time, please charge it after it cools down.
2. The ambient temperature is too low. The ambient temperature suitable for charging the DELTA MAX is between 0℃ and 45℃. If the ambient temperature is too low and the cell temperature is lower than 0℃, please move DELTA MAX to a warmer place.
3. The charging voltage or current is too low. Please charge the device according to the charging standard specified in Question 1.
4. Change the charging method or cable. For example, if solar charging doesn’t work, but car charging does, it means that the solar panel or MC4 cable is broken. You can try charging DELTA MAX again with another MC4 cable or solar panel.
5. If all the above solutions cannot solve your problem, please contact Energia Customer Service at [email protected] or 020 8064 0335, ideally with a video of the attempted charge.
11. WHAT TO DO IF THE DELTA MAX OVERLOADS WHILE CHARGING?
This can be seen when the RECHARGING TIME icon, the exclamation mark icon, and the OVERLOAD icon flash together on the charging overload screen.
1. Check whether the input current is too high. If it is confirmed that there is no problem, restart the machine and try to charge again.
2. If the overload still occurs again, please contact us.
12. WHAT TO DO IF THE SCREEN SHOWS FULL CHARGE, BUT THERE IS STILL CHARGING POWER?
The charging logic of DELTA MAX is that the battery level indicator turns 100% first while it continues to charge for a while until it’s really fully charged.
13. WHAT TO DO IF THE CAR CHARGER DOES NOT CHARGE DELTA MAX?
1. Confirm whether the 12V cigarette lighter socket of the car has normal power output. You can check the car DVR or try charging your phone in the car via the cigarette lighter.
2. Charge DELTA MAX with a third-party car charger cable to check if the problem lies in the DELTA MAX Car Charger Cable, or use a solar panel to charge the DELTA MAX. If it works, the fault is in the EcoFlow Car Charging to the XT60 Cable. In this case, you need to change the cable. In this case, or if the solar panel can’t charge your DELTA MAX, please contact Energian Customer Service.
14. WHAT IS THE STANDARD OF CAR CHARGER PORT?
The car charging port XT60 is a standard car charger’s input port. You can power your device with a DELTA MAX Car Charger Cable (1.5 m) or a third-party car charger cable to charge.
DELTA MAX OUTPUT POWER

3. WHAT ELECTRICAL APPLIANCES ARE SUPPORTED BY THE DELTA MAX?
DELTA MAX supports appliances with rated power within the standard DELTA MAX output power range of 1800W. You can see the appliance-rated power in the user manual or on the nameplate, or calculate it according to the formula W=U*I (rated voltage multiplied by rated current). Note that since the start-up power and continuous power of different brands of products are different, it depends on the actual measurement to determine whether it can be supported. If in doubt, please contact customer service at [email protected] or 020 8064 0335.
4. DOES THE DELTA MAX SUPPORT THE X-BOOST FUNCTION?
Yes, the DELTA MAX supports X-BOOST.
5. WHAT TO DO IF DELTA MAX CANNOT POWER MY ELECTRICAL APPLIANCE?
1. Check whether the relevant DC or AC switch on the DELTA MAX is turned on.
2. If the AC or DC switch is turned on, and the appliance is still not running, please confirm whether the output power of DELTA MAX meets the requirement of charging the electrical appliance.
3. When the power of DC and car charger is less than 1 watt, the charging power will not be displayed. If the actual device is charging, you can try charging another appliance.
4. When the screen displays an overload alarm, it means that the charging power is too high. Please shut down and cool down for a while or replace it with a low-power device, then try charging again (shut down and cool the machine for 30 minutes and restart).
5. After the AC switch is turned on, if the power of the electrical appliance is less than 10W, the power detection is equivalent to no power output, and the AC switch will be automatically turned off after 12 hours. At this time, the switch needs to be turned on again.
If the above information does not resolve your issue, contact customer support at [email protected] or 020 8064 0335.
6. WHAT TO DO IF THE USE TIME OF AN ELECTRICAL APPLIANCE IS TOO SHORT?
Due to the different power of each appliance, the discharge efficiency of DELTA MAX will be less than 100%, resulting in the usage time of the appliance being lower than the theoretical time. This is particularly the case with AC (mains powered) appliances where inverter losses are likely to reduce the use time by 15-25%. If the usage time is less than what is indicated here, contact customer support.
7. WHAT TO DO IF THE DELTA MAX DISCHARGES TOO QUICKLY?
1. Check if there are any high-power electrical appliances connected. DELTA MAX’s battery capacity is 2016Wh. Normally, if the power of connected electrical appliances is ~2016W (DC), DELTA MAX’s battery will run out in about 1 hour. For AC (mains powered) appliances, inverter losses are likely to reduce the use time by 15-25%.
2. If the use time appears too low, calibrate the DELTA MAX as described above, and do a complete charge and discharge.
8. WHAT TO DO IF THE STANDBY TIME OF DELTA MAX IS TOO SHORT?
1. Check whether it is in a room-temperature environment, if it is in a low-temperature environment, place it in a room-temperature environment for use.
2. Calibrate the DELTA MAX as described above, and do a complete charge and discharge.
9. WHAT TO DO IF THE OUTPUT OVERLOADS?
AC output overload: The AC icon will appear on the screen, and the OVERLOAD icon flashes
1. Please check whether the power of the connected device meets our power range. Connect the 2400W-3000W power device to confirm whether the X-BOOST is turned on. If the default is turned on, connect to the APP again;
2. In EPS mode, we support the maximum power of 2200W, and confirm whether the electrical equipment is within this range;
3. The instantaneous power of the electrical equipment is too large, causing it to fail to operate;
DC output overload: The USB icon and the OVERLOAD icon will flash together on the screen
1. The output of the DC-car charger is overloaded, confirm whether the rated current of the electrical equipment power is within 8A, if the current is too high, it will cause overload, and even the car charger will burn out.
2. The output of the DC-USB-Type C interface is overloaded, please confirm whether the electrical equipment is within the current limit of the interface
10. WHAT TO DO IF NO OUTPUT OF USB-A, USB Type-C PORTS OCCURS?
1. Confirm whether the DC switch is turned on and whether the DC switch light is always on after it is turned on.
2. Change to a different USB-A port, try to connect to other USB ports such as USB-C, and confirm whether it is just the problem of a single port.
3. Replace the USB cable to confirm whether the cable is faulty.
4. If there is no output from the USB port after the above methods, provide a video explaining the fault and contact the after-sales service.
11. WHAT TO DO IF THE LIGHT BULB FLASHES FREQUENTLY?
1. If the light bulb only flashes occasionally when turned on, it might be caused by instant charging voltage fluctuation. In this case, normal product use won’t be affected.
2. If the light bulb constantly flashes, you can change it with a new one. If the problem remains after you change to a new bulb that meets DELTA MAX’s charging standards, you can contact EcoFlow Customer Service and provide the flickering video and the light bulb’s charging specifications.
12. WHAT TO DO IF WHEN DELTA MAX IS CONNECTED TO THE SPEAKER, THE NOISE IS TOO LOUD?
Allow customers to try to connect other brands of speakers to confirm whether the noise still exists. Some speakers’ EMC electromagnetic compatibility is not good enough. It is a problem with the speaker itself, not a fault of the product itself. If the noise still exists after replacing the speaker, please make a video showing the fault and contact the after-sales department.
13. WHY DOES MY REFRIGERATOR POWER OFF AUTOMATICALLY?
If the refrigerator is connected to a 12V car charger port, the DC and AC buttons power off. Cause the refrigerator works for a while and then the standby, the power of standby is too low to be detected by DELTA MAX. So DELTA MAX will power off automatically in 30 minutes with low output. Please turn on the DC button when you use the refrigerator.
14. WHAT TO DO IF WHEN DELTA MAX IS CONNECTED TO THE FAN, THE NOISE IS TOO LOUD?
Confirm whether it is fully charged if the device has just been fully charged, the temperature is too high, the fan speed is high, and the sound may be loud. This can reassure the customers. The fan is designed to cool the device and protect the device. Even if the sound is loud, there will not be an impact on its use. If the customer is still not at ease, guide the customer to take a video at a distance of 2 meters from the device, and the technology department will confirm remotely whether there is an abnormality.
15. WHEN AND WHY DELTA MAX SHUTS DOWN?
1. The battery of DELTA MAX runs out, please charge the battery.
2. The default standby time of this product is 2 hours. If the other switches’ output power is not turned on and the product is not connected to any load, the product will automatically shut down after 2 hours, and the standby time can be set on the APP.
16. WHAT TO DO IF DELTA MAX DOES NOT BOOT?
1. If the battery is dead, charge it first and try to turn it on. If it cannot be charged, please refer to the relevant instructions.
2. If there is no response after short pressing or long pressing the power button for 3 seconds, please contact the after-sales department.
17. IS IT POSSIBLE TO USE DELTA MAX IN SERIES?
1. When charging, charge the one with low power first, then charge the battery itself and the power pack. Balance before charging.
2. When discharging, discharge the one with high power first, then discharge at the same time.
3. The multi-level series can be used directly by connecting to the port of the power pack.
THEME: X-BOOST FUNCTION
1. WHAT IS DELTA MAX X-BOOST FUNCTION?
DELTA MAX supports the X-Boost function to supply power to devices with a rated power of 3000W, and will not cause the device to fail because of an overload protection. When using the X-Boost function, the output power of this product is still the rated output power of 2400W.
This product supports devices with a maximum of 3000W, at this time, the rated output power is still 2400W
2. HOW USE THE X-BOOST FUNCTION?
DELTA MAX has the X-Boost function enabled by default. You can use the EcoFlow App to turn this function on or off.
The X-Boost function is not available in the following situations:
the AC output is turned on in the charging state (in bypass mode at this time) and the X-Boost mode is turned off.
The X-Boost function is more suitable for heating and electrical equipment, but not for all electrical appliances. Some electrical appliances equipped with voltage protection (such as precision instruments, etc.) are not suitable for the X-Boost function. To confirm whether the device is compatible with the X-Boost function, please refer to the actual test.
THEME: DELTA MAX SOLAR PANEL CHARGING
1. WHAT IS THE MAXIMUM SOLAR CHARGING INPUT TO DELTA MAX?
Max. solar charging input 800W 11-110V DC 10A (maximum)
Charging time: 3.2-6.3 hours (400W x 2 in series); 4-8 hours (110W x 2 in series) or (160W x 2 in series)
2. CAN OTHER THAN ECOFLOW BRANDS OF SOLAR PANELS CHARGE DELTA MAX?
The MC4 interface supported by DELTA is a universal interface. Note that the charging input of the connected solar panel is within 800W 11-110V DC 10A.
3. HOW CONNECT SOLAR PANELS – IN SERIES OR PARALLEL?
1. The standard EcoFlow 400W solar panel supports a connection up to 2 in series
2. For other solar panels, if it is a solar panel with a wattage lower than the standard 400W, the solar panels can be used in series if the total voltage and current are not more than 11-110V and DC 10A, respectively. According to the specific parameters, it can be connected in parallel or in serial connection, but the usage of solar panels with different wattages is not recommended.
4. WHAT TO DO IF SOLAR PANELS DO NOT WORK?
1. Solar panels must be placed outdoors for use. If being placed indoors, this function cannot be used.
2. Check whether the display screen has abnormal prompts, and operate according to the abnormal prompts.
3. Check whether there is any problem with the connection method, remove incorrect connections, and try again.
4. The total voltage and current can be used not more than 11-110V DC 10A. Please confirm whether the connected voltage and current are within this range and check whether the positive and negative poles are connected reversely.
5. If you are using a third-party connection cable, it is recommended that the cable length does not exceed 3m. If it exceeds, use a wire harness with a diameter of 6.5mm and a wire diameter of 4mm², otherwise, there will be no display of input.
6. Recommended to the customer to use the car charger to test the connection port to see if the DELTA MAX can be charged. If possible, it means that there is a problem with the solar panel connection or the solar panel itself. If the car cannot be charged, provide a video of the operation and contact the after-sales department.
7. WHAT IS THE OUTPUT POWER OF THE SOLAR PANEL IN VARIOUS WEATHER CONDITIONS?
1. The light is strong, the angle is vertical, and the output power is about 80% of the rated power. Taking a 110W solar panel as an example, the actual output power is about 90W
2. Cloudy: 20~30W
3. Cloudy days: 5~10W (In the case of low sunlight on cloudy days, it is not recommended to connect to solar panels for charging. The standby power of the device may be greater than the solar input power, which may cause damage to the battery of the device.)
4. Rainy day, night: 0W (The expression can be optimized for low battery, and if the current input power of the solar panel is very low, charging with solar power is not recommended. Otherwise, it will always be determined that the charging state does not shut down, and the consumption of the standby power is higher than the input power, causing the battery voltage to leak and affect the battery life.)
8. MATERIAL OF ECOFLOW 400W SOLAR PANEL?
Monocrystalline silicon, conversion efficiency: 22~23%.
9. WHY IS THE CHARGING POWER OF MY SOLAR PANEL SO WEAK?
If you are connecting an EcoFlow 110w solar panel, the charging power may be influenced by sunlight intensity and angle:
1. You can use the solar panel between 9:00 a.m. and 3:00 p.m. when the sun’s rays are strongest. Avoid using it on a cloudy day or put it in a shady place.
2. Place the solar panel at 90° to the sunlight so that the equivalent area is the largest, and the solar charging power is higher.
3. Check if the Quiet Charging on the app is on.
THEME: DELTA MAX EMERGENCY POWER SUPPLY (EPS) MODE
1. WHAT IS THE EPS MODE?
When your DELTA MAX is plugged into the wall, any electronics plugged into DELTA MAX are powered from the grid and not its battery. In EPS mode, when the battery power is between 97% and 100%, the AC input will not charge the battery. When the power is below 97%, the AC input will be used as a bypass output and will also charge the battery. When power from the grid stops, as in a blackout, DELTA MAX automatically switches to battery power within 30ms.
2. IS DELTA MAX EPS MODE THE SAME AS UPS FUNCTION?
DELTA MAX uses a non-universal UPS function and is only used as an EPS. When you connect the grid power to the AC Input Port of the product through an AC cable, you can power electrical devices through the AC Output Port (AC power will come from the grid and not the power station in this situation). In case of a sudden blackout, the product can automatically switch to the battery-powered supply mode wit
