DELTA MINI AC AND CAR CHARGING

1.WHAT ARE THE CHARGING STANDARDS? HOW LONG DOES IT TAKE TO CHARGE MY DELTA MAX?
It supports three charging methods: mains charging, car charging, and solar charging, mentioned as follows:
Mains charging
Voltage of AC charging input: AC 220-240V (50Hz/60Hz) Current: 10A
AC charging input power: X-Stream supercharges 900W max.

Custom charging power: 200-900W (factory default 200W) APP can set the charging power range.
X-Stream supercharge charging time: 1 hour 0-80% 1.6 hours 0-100%
Charging with a car charger
Input of car charger: 12V/24V, DC 8A (maximum)
Charging time: 9 hours
Charging with solar panel
Solar charging input 300W 11-75V DC 10A (maximum)
Charging time: 4-8 hours (110W x 3 in series) or (160W x 2 in series)

2. WHAT TO DO IF CHARGING POWER IS LOW?

1. If the temperature is too high, turn off the machine or stop the load, and let DELTA MINI cool down for some time
2. If the temperature is too low, place DELTA MINI in a place with high surrounding temperature or with electrical appliances to discharge for a while, let the battery heat up before charging.
3. The charging power of the machine is related to the SoC of the battery. When the machine starts charging from 0% or is about to be fully charged, it is normal that the charging power gets lower.

3. WHAT TO DO IF CHARGING POWER HOPS FOR A SHORT TIME?

Carry out SoC calibration and do a complete charge and discharge cycle,  then try to see if reappears during charging. If it still occurs, please provide a video explaining the fault and contact the after-sales service.

4. DOES IT SUPPORT CHARGING WHILE USING?

Yes, DELTA MINI supports charging and discharging when charging in vehicles, solar panels, etc. However, when the battery of the machine is low or is about to run out, it is best not to output while connecting to DC charging (solar/car 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. WHETHER THE SIMULTANEOUS ACCESS OF AC AND CAR CHARGER IS SUPPORTED?

No, currently only supports one of them to be connected separately for charging

6. WHAT TO DO IF THE BATTERY FULL CHARGE TO 100% IS UNABLE? 

Conduct SoC calibration i.e. fully discharge and charge the battery.

7. IS IT POSSIBLE TO USE THE OTHER PRODUCTS TO CHARGE DELTA MAX?
In addition to the home power grid, car chargers and solar panels can charge DELTA MINI, and use other equipment such as generators or inverters, etc. If 220-240V (50Hz/60Hz) AC power can be provided, connect to the AC port of DELTA MINI. The output is a sine wave, which can be used to charge DELTA MINI.

8. WHETHER THE TOTAL HARMONICS DISTORTION (THD) LEVEL BE USED AS THE BASIS FOR JUDGING THE CHARGING OF DELTA MINI?

No, it depends on the specific waveform of ac. Ecoflow products currently support a total of more than 30 waveforms. The only thing that cannot be supported is the waveform with the oscillation point at 0. This has nothing to do with the THD size, and it is related to the position of the waveform oscillation, so it does not support the charging of the minimum or the maximum THD. The determining factor of whether DELTA MINI can be charged is the output power of the customer's generator. It depends on whether its current is within the supported range of DELTA MINI, and one cannot only judge by the THD.

9. WHAT TO DO IF NO CHARGING OCCURS?

1. The charge temperature is too high. The charge temperature of DELTA MINI is between 0℃ and 45℃. If you have used DELTA MINI with high-wattage appliances for a long time, please charge it after it cools down.
2. The charge temperature is too low. The charge temperature of DELTA MINI is between 0℃ and 45℃. If the ambient temperature is too low and the cell temperature is lower than 0℃, please move DELTA MINI 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 MINI again with another MC4 cable or solar panel.
5. If all the above solutions cannot solve your problem, please contact EcoFlow Customer Service and provide a video of your charging problem.

10. WHAT TO DO IF CHARGING OVERLOADS?

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 large, 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 after-sales processing.

11. WHAT TO DO IF THE SCREEN SHOWS FULL CHARGE, BUT THERE IS STILL CHARGING POWER?

The charging logic of DELTA MINI is that the battery level indicator turns 100% first while it continues to charge for a while until it's really fully charged.

12. WHAT TO DO IF THE CAR CHARGER DOES NOT CHARGE DELTA MINI?

1. Confirm whether the cigarette lighter 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 MINI with a third-party car charger cable to check if the problem lies in the DELTA MINI Car Charger Cable. Or you can use a solar panel to charge DELTA MINI. If it works, it can be sure that the fault is in the EcoFlow Car Charging to XT60 Cable. In this case, you need to change the cable. If the solar panel can’t charge your DELTA MINI, please contact EcoFlow Customer Service.

13. 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 MINI Car Charger Cable (1.5 m) or a third-party car charger cable to charge.

DELTA MINI OUTPUT POWER

1. WHAT IS DELTA MINI OUTPUT POWER?

DELTA MINI supports AC output, USB output, car charger output, and DC5521 output, which is a total of 4 output methods, providing a total of 9 output ports:
1. AC output (pure sine wave) - 2 pcs

2. IS THE 100% PURE SINE WAVE USED IN THE DELTA MINI OUTPUT?

There is no 100% pure sine wave. Any product contains a certain ratio of harmonics. The harmonic rate of EcoFlow products is as low as 3%, which can drive some inductive loads on the market, such as induction cookers.

3. WHAT ELECTRICAL APPLIANCES ARE SUPPORTED BY DELTA MINI?

DELTA MINI supports appliances having rated power within the standard DELTA MINI output power range of 900W. You can see the appliance-rated power through the user manual or 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. 

4. DOES DELTA MINI SUPPORT THE X-BOOST FUNCTION?

Yes, DELTA MINI supports the X-BOOST function.

5. WHAT TO DO IF DELTA MINI CANNOT POWER ELECTRICAL APPLIANCES?
1. If it is DC charging and AC charging, confirm whether the DC or AC switch is turned on
2. If the AC or DC switch is turned on, and it still cannot be charged, please confirm whether the output power of DELTA MINI 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. If there is still an overload prompt, ask the customer to provide a screenshot or video and contact the after-sales department)
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

6. WHAT TO DO IF THE USE TIME OF AN ELECTRICAL APPLIANCE IS TOO SHORT?

Due to the different power of each consumer, the discharge efficiency of DELTA MINI will be less than 100%, resulting in the usage time of the consumer being lower than the theoretical time. The specific efficiency should be calculated based on the actual power. If the customer has any questions, the specifications of the consumer can be given to the after-sales department for calculations. 

7. WHAT TO DO IF THE LOSS OF POWER OF DELTA MINI IS TOO QUICK?
1. Check if there are any high-power electrical appliances connected. DELTA MINI's battery capacity is 882Wh. Normally, if the power of connected electrical appliances is ~882W, DELTA MINI's battery will run out in about 1 hour.
2.  It can guide the customer to perform a complete full charge and discharge, do a soc calibration, and do a complete charge and discharge.

8. WHAT TO DO IF THE STANDBY TIME OF DELTA MINI 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. It can guide the customer to perform a complete full charge and discharge, do an SoS calibration, 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, and connect the 1400W-2200W 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 1400W 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 MINI'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 MINI 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. WHAT TO DO IF WHEN DELTA MINI 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.

14. WHEN AND WHY DELTA MINI SHUTS DOWN?

1. The battery of the DELTA MINI 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.

2. It supports connecting up to 2 fully-charged DELTA MINIs in series through the AC line to meet the needs of professional users for large capacity. Please note EPS mode can't work with multi-leveL series.

X-BOOST FUNCTION

1. WHAT IS DELTA MINI X-BOOST FUNCTION?

DELTA MINI supports the X-Boost function to supply power to devices with a rated power of 2200W, 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 1400W.
This product supports devices with a maximum of 2200W, at this time, the rated output power is still 1400W

2. HOW USE THE X-BOOST FUNCTION?

DELTA MINI 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.

DELTA MINI SOLAR PANEL CHARGING

1. WHAT IS THE MAXIMUM SOLAR CHARGING INPUT TO DELTA MINI?

Max. solar charging input 300W 11-75V DC 10A (maximum)
Charging time: 4-8 hours (110W x 3 in series) or (160W x 2 in series)

2. CAN OTHER THAN ECOFLOW BRANDS OF SOLAR PANELS CHARGE DELTA MINI?

The MC4 interface supported by DELTA is a universal interface. Note that the charging input of the connected solar panel is within 300W 11-75V DC 10A.

3. HOW CONNECT SOLAR PANELS - IN SERIES OR PARALLEL?

1. The standard EcoFlow 110W solar panel supports a connection up to 3 in series
2. For other solar panels, if it is a solar panel with a wattage lower than the standard 110W, the solar panels can be used in series if the total voltage and current are not more than 11-75V 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 MINI 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 110W 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.

DELTA MINI EMERGENCY POWER SUPPLY (EPS) MODE

1. WHAT IS THE EPS MODE?

When your DELTA MINI is plugged into the wall, any electronics plugged into DELTA MINI 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 MINI automatically switches to battery power within 30ms.

2. IS DELTA MINI EPS MODE THE SAME AS THE UPS FUNCTION?

DELTA MINI 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 within 30ms. As a basic UPS function, this function does not support 0ms switching. Please do not connect the product to any device that requires 0ms UPS, such as data servers and workstations. Please test and confirm the compatibility before using the product. We recommend that you only charge one device at a time and avoid using multiple ones at the same time to avoid overload protection.
