Since the power supply is a single-port USB output and the default Apple resistance, it may be too slow to charge many Android devices. This line can solve the problem of slow charging of most Android devices, such as Samsung NOTE2, but it is impossible for any mobile phone to be 100% guaranteed. Short-circuit, please understand this.

Technical data: Charging input: 16V-24V/1.6A   Interface 5.5X2.1（The original charger with the same interface and voltage range is sufficient. Note: The above price does not include the power supply）

DC output port:3.6V/5V/6V/9V/12V/15V/16V/19V/21V=3.3A(MAX)（With current limit and temperature protection）

USB output port:5=2.1A（max）Only when the switch is set to 5V, there is output, and the other gears are set in the open.

The above parameters shall prevail. The parameters on the back of the physical box are printed incorrectly, hereby explain!

                 Dimensions:16.2cm long*8.2cm wide*2.2cm thick.

It is best to choose batteries with low internal resistance and real capacity: Samsung, Sanyo, Sony and other brand batteries, because a few dollars of batteries not only have a virtual capacity, but also have a large internal resistance. It is no problem as a load for LEDs with small currents, and as high power. When the mobile power supply is used, all the remaining electricity is consumed by its internal resistance.

Note: The input charging base is 5.5*2.1-2.5mm, so the output plug of the charger must be 5.5*2.1-2.5mm, otherwise it will not be charged! ! !

Note: Due to the shell mold, the shell voltage identification is still the shell of the first generation.There is 7.5V on it, and now the shipping boards are all new versions, there is no 7.5V, the second-generation voltage range adjustment operation please refer to the above picture, If you mind, please do not place an order!

Simple operation instructions:

1. The USB port will have an output voltage when the right voltage regulator is set to 5V. For example, when the voltage is adjusted above 12V, only when the right voltage regulator is set to the top, the left voltage regulator will work.

2. To view the battery voltage, directly press the maximum button above. To view the output voltage of the DC port, you must press the small button on the left while pressing the big button.

3. If there is no response from installing the battery, just press the small button on the right side of the front.

4. When charging mobile phones and laptops, connect the device, press and hold the big button for 1-3S after the device prompts to charge, release it.

5. There will be output only when there is equipment load, otherwise, press the small button and it will automatically shut down after release.

Reminder: The device load current, when the charging current is very small, the power cannot be charged, it will automatically shut down（Such as bluetooth headset）, Also hope to pay attention!

Improvements in the second edition:

1. In order to solve customer feedback that the USB port''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s multiple voltage output may burn out the digital equipment, now the USB port is changed to the 5V file to output 5V, and the other files are set in the open and do not output.

2. In order to solve the problem that the USB adapter cable is difficult to find and it needs to be carried inconveniently, it is changed to: all 9 levels of voltage are output from the DC port, so that one adapter cable can link all devices. As soon as the voltage adjustment switch reaches the top gear, the voltage adjustment function is controlled by switch 2.

3. In order to solve the problem of easy damage to the circuit reported by customers, we separate the activation button of the lithium battery protection board and place it on the right side of the USB port, so that when the output is abnormal, the activation button will not be accidentally forced to output, which greatly increases the reliability of the circuit .

 4. Regarding the appearance problems reported by customers, we have modified the mold if it can be corrected, and hope that everyone can be satisfied.

 5. Some customers worry that the charging port and the output port are both 5.5*2.1mm DC ports, and the wrong plug will damage the circuit. Here is an explanation, the charging port will only input power, not output power, so it is not It will damage any digital equipment, and the mobile power supply also has a withstand voltage of 25V, and it will not be damaged; especially the digital equipment as the power receiver will not output power at all, so it is impossible to damage the mobile power supply. The purpose of our design is to reduce a patch cord, so that a patch cord can be used as both a charging switch and an output switch, which is convenient for everyone to use.

6. There are many other improvements, so I won''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t list them all.

After the above improvement, the stability of the product and the convenience of use have been greatly improved. I hope everyone can be satisfied. We will continue to improve in the spirit of the ISO9001 system!

Note: When the 3.6V file is unloaded, it will be raised to 4.nV, which will not affect the use of 3.7V equipment. If you think it will burn your equipment because of this, or if you want to refund the compensation, please take a detour!

    4. This product can replace the internal battery of the notebook, and can also be used as a UPS uninterruptible power supply for notebook computers; because it has the ability to seamlessly power the notebook while charging the box with the original charger of the notebook, city power and battery The power supply switching time is less than 1 second; if your notebook battery has a broken circuit and the battery core is intact, then you only need to buy a box, which can save you thousands of yuan, because a better original battery costs thousands of yuan. .（Note: If it is a UPS with input and output at the same time, it is equivalent to directly supplying power from the input power supply, and the output voltage is the same as the input power voltage.3.6-9VPartly unaffected）

    5. This product has ten levels of voltage output, covering almost all digital products on the market, so it is widely used.

    6. The digital voltmeter head, intuitively and accurately displays the battery voltage, battery power, and output voltage.

Usage method:

1. If the polarity is marked, put in a good 3.6V/3.7V 18650 lithium battery with low self-discharge（3-6 sections can be used, please place a battery position apart when 3 sections are used to form a three-string method）.

2.Charge:Use 16V-24V power adapter（Most of the original chargers are available）The polarity center is positive. Insert the output port of the adapter into the charging base. At this time, the voltmeter head will display the battery voltage and charge. When the battery voltage slowly rises to 12.4-12.8V, the charging is completed, and the charger is pulled out at this time. Just download.     

      
3.Power display:Press the switch button on the panel, the voltmeter head will display the real-time battery voltage, and the output switch will be turned on at the same time, and the power indicator will go out when you let go.

4.According to the nominal voltage of the original adapter of the digital device, select the output port and set the switch to the required gear. At the same time, press the output switch on the panel and the small button on the left of the corresponding test position to check the display on the meter head. Whether the voltage is suitable, finally connect the output port of the box with the charging port of the digital device with the corresponding adapter cable, and finally press the button on the panel for 2-6S to charge (there are many digital products with a charging identification system inside, such as your product voltage Yes, but the charging is not displayed yet, then you have to consider using an adapter cable or adapter with a special identification circuit for the device. Note that the USB port can only output when the voltage on the right side of the block is set to 5V.

5. After the device is fully charged, the electronic switch will automatically turn off（Except for equipment with larger holding current）To enter the power saving mode.

6. When used as a UPS uninterruptible power supply for notebooks, you only need to plug the original charger into the charging port, and connect the output port to the power input port to uninterruptedly supply power to the notebook. At the same time, it charges the internal battery of the box. The response speed is within 1 second when the power fails.

Note that the power consumption devices all generate heat during operation. The greater the current used, the higher the heat generation. The heat generation is within the design normal range, so don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t worry too much.

The battery is only for demonstration and needs to be purchased separately by the buyer

Sometimes the product may be upgraded and improved, and some components will be changed. If there is no obvious change in product parameters and characteristics, no other additional notification will be made.

Frequently Asked Questions:

1).Can 1-6 batteries work?

Answer: In order to increase the power, a combination of 3 series and 2 parallel is used, so at least 3 batteries must be placed in each other to form 3 series.

2）Can the original charger of my laptop be used with 19V4.7A?

Answer: The charger is for charging the notebook and using it at the same time, so it will be larger, but the actual power consumption of the notebook will be lower, so this product should be able to charge or power the notebook with a higher power, and can fully charge the internal battery of the notebook. Use the power box later to extend the use time.

3）How long is the notebook with the six batteries and how many times can I charge the phone?

Answer: The length of the discharge time is related to the battery capacity, number of cells, mobile phone battery capacity, discharge current and other factors; time =（The actual battery capacity * the number of cells * 3.7v * battery discharge efficiency 0.8 * circuit boost efficiency 0.9）/（Output voltage * actual output current）. If the discharge current is large, the efficiency will be reduced; after the actual use of 6 3100mAH Panasonic lithium batteries, you can bring Dell（19V3.34A）Books are close to 2H. When charging low-power devices such as mobile phones, the efficiency is felt to be low, because the circuit has a meter, as long as the output is turned on, there will be power consumption of less than 0.3 watts, and the discharge time will be long if the power is discharged, so the power consumption of the meter It will have a greater impact. In addition, the mobile phone is charged with a 5V battery, which is 3.7V, so the capacity cannot be calculated simply. The number of times = {(battery capacity*3.7v*0.8 battery discharge efficiency*circuit voltage reduction efficiency 0.8)-meter head (20mA*12V *Total output time))/5V*cell phone battery capacity

4）Why can''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t my mobile phone be charged, but other people''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s mobile phones can?

Answer: Many mobile phones now have identification resistors for charging. Although the power supply has made identification resistors, there are many devices on the market, and manufacturers have different requirements. Although it can adapt to most mobile phone models on the market, such as Apple, Samsung, and HTC Wait for charging, but there may still be very few cases where individual models cannot charge normally.

5)Why is it that the battery voltage is 11v when the load is not connected（10.5-12v）, It is turned off after connecting the load, and the load can be charged only after pressing the activation and output switches at the same time?

 Answer: When this happens, you have to check the voltage displayed on the meter when the load is being charged. If the voltage displayed at this time is about 10V or below, it means that your battery is not sufficiently charged or is in the battery. The resistance is too big. Because the display shows less than 10v when loaded, each cell should be lower than 3.3v, the actual voltage will be lower, because the meter shows the average value, the peak voltage will be lower, so the protection board will cut off the output; the battery voltage when there is no load If it is false, the load voltage is the real battery. Maybe you would say that my battery has not been tested with an internal resistance meter, or that it is easy to use on an ordinary mobile power supply, or that it is very bright when used on a strong light flashlight! This is because the ordinary mobile power supply is only a few watts and the LED light power is smaller, so the battery internal resistance is not high. This mobile power supply is nearly 70W at the maximum, and the battery needs to provide nearly 5A at full load output. It is an ordinary mobile power supply. LED lights are even more than 10 times higher than that of LED lights, so the internal resistance of the battery is higher. Of course, we have tried genuine Samsung, Sanyo, Sony and other 18650 lithium batteries are sufficient. Just aging, do not use domestic low-quality lithium batteries. Genuine Samsung lithium batteries are also very cheap, only about 16 yuan, which is very cost-effective.

6) When charging the notebook, the output seems to be unstable. Sometimes the notebook is displayed as charging, and sometimes it switches to the power mode, that is, it only supplies power and does not charge?

Answer: Some books consume a lot of electricity when charging and using, exceeding the maximum limit current of the box 2.8-3.3A, so the box will reduce the output voltage to limit the output power, so the above phenomenon will occur, and if the box temperature is high When the temperature protection starts, the output current will be reduced by half. It will be like this too.
