Because many buyers have poor quality chargers themselves. Unable to support high-power output for a long time, it will be damaged when charging our power bank. Therefore, this charger is recommended by us.
Product Description
Note: After installing the battery, it needs to be charged and activated
217 refers to the 18650 battery model
Product upgrade introduction
This product is the third generation upgrade of the original 5389 power bank. The upgrade mainly includes: 1. increasing DC output, 2. adding an independent Coulomb meter and color display, solving the problem of inaccurate display in the previous style. 3. Add LED lighting function.
Battery and display introduction
The product with coulombmeter, coulombmeter needs to be preset in advance, therefore, our preset value of 21700 battery 4900mah, 18650 battery 2900mah. The best advice is to use a preset capacity battery. Recommended scope of use: The 21700 battery can use 4800-5000mah battery, the error is 100mah per section, the eight section capacity error is 800mah, almost will not affect the use, the error can be within the acceptable range, the 18650 battery is similarly recommended 2800mah-3000mah, the error is small, the impact is small. However, if you need strict consistency or other batteries with large capacity gaps, you can contact us to modify the program, but the charge is 4.50 US dollars. However, the program can be used normally without modification, but the display is not accurate. However, because of various factors, whether modified or not modified, there will be objective errors, not absolutely accurate, do not mind to buy.
Note：Installing a 5000mah battery does not mean that it will get 5000mah of electricity, which contains conversion rate, loss and other factors, but generally calculate the total capacity directly according to the capacity of the battery, such as 4 5000mah batteries, the total capacity is 20000mah, but the actual conversion is lower than 20000mah. This is an inevitable theoretical wear and tear.
Note：Install the battery in strict accordance with the positive and negative electrodes on the circuit board, otherwise it will burn the circuit board during installation. Guests are responsible for any damage. Maintenance costs are high, but replacement boards can be sold at a low price.
Notice before purchase
1.both options do not include batteries, batteries please bring your own. Because of the coulombmeter, it is necessary to fill the battery, if you can contact customer service to pay to change the capacity. Only a 4.2v lithium battery can be used, and nothing else.
2.fast charge the maximum power of 100w, so the battery must be a power battery (continuous discharge capacity is greater than 3-4a), otherwise the input or output can not reach the maximum power, and will heat seriously!
3. The charging bank adopts a 4-series 2-parallel structure, requiring the same battery model, including battery capacity and internal resistance, and battery voltage before installation, otherwise the output will be turned off in advance.
4. please pay attention to observe the positive and negative poles of the circuit board, the battery is strictly prohibited, once it will be burned, and the freight will take care of itself. The maintenance cost is comparable to the price of each set, please observe carefully before installation! Must be installed in strict accordance with the logo on the circuit board!
5. the 18650mAh and 21 700mAh in the above option represent not the battery capacity but the battery box 18650 and 21700 models, there is a need for the corresponding model can choose!
6. before the purchase of spare parts products can contact customer service to assemble the video, please confirm that they have enough hands-on ability and tools, spare parts do not return, do not change, do not warranty! No return, no replacement, no warranty! No return, no replacement, no warranty!
7.it is forbidden to link the two-way c port module, which may cause frequent switching between modules can not be identified, and serious damage may be caused. The two-way c port of the product can only be connected to one-way electrical appliances or chargers, such as charging heads, mobile phones and other electrical appliances.
8. Please test whether the product is in good condition and whether the function is desired before assembling the shell. Because the acrylic shell protective film is secondary, the protective film -8 can not be fully refunded, 15 yuan per shell!
9. The finished 18650 contains 8 domestic 29000mah power batteries with a total capacity of 23200mah; The finished product 21700 contains 8 domestic Yiwei 4900mah with a total capacity of 39200mah.
10. the product is shipped without batteries, shipped as spare parts, the need for Phillips screwdriver tools, do not need solder. Assembly requires a certain hands-on ability, if there is no battery or do not want to do it, you can contact us to customize the finished product with battery! If manual damage during assembly is not covered by the warranty (such as the battery is inverted)
Product upgrade details
This product is a new upgrade of 5389 hot selling models, featuring high cost performance! There are few competitors in the same price range with displays and extensions. The expansion port can also be modified to other own modules or other functional modules, practicality and playability greatly improve the basic version two-way fast charge maximum power of 100w, the expansion module after the three type-c can reach a maximum of 300w power. (Note: The basic version has 1 c port, and there will be 3 c ports after the expansion module) The main upgrade points of this product and the old 5389 are:
1, increase the screen, can display the real-time power of 3 c ports, dc power.
2. Add coulombmeter chip and color display. Can accurately count power, whether there is no module expansion does not affect the actual power statistics, the screen is 1.54 inches wide Angle ips color screen. System stable, almost
There is no possibility of crash. The real-time power and dc power of the three c ports can be displayed.
3. Add dc bidirectional ports. After connecting the 16.8v charger, the product can be used as a desktop power station or ups, for example, the dc port is connected to 16.8v to charge the battery, and the remaining three c ports can be output. Or connect the solar mppt module to realize real-time solar charging.
4.add led lighting function. The main problem with the original 5389 mobile power socket is expansion
The power display after the module is inaccurate, because the expansion module is taken directly from the positive and negative battery terminals, and does not pass through the 5389 power display. Now with the addition of the coulombmeter chip, the power display is more accurate, and real-time current and voltage can be seen.
We independently develop high-power modules to expand functions
This charging bank supports the upgrade of a two-way fast charge function, which is 60w and 120w two-way pd fast charge module. After the upgrade, it can support the bidirectional fast charging function while charging, such as the laptop charger to charge the charging treasure, and then connect a cable from the charging treasure to the computer, you can realize the charging treasure + laptop charging at the same time. You can also charge your phone or other devices via a usb port. If you do not need to charge while discharging, you can also output to two fast charging devices at the same time. Note: After the upgrade, the power is very large, and the battery performance must be very good (high discharge rate, consistent capacity internal resistance), otherwise the power cannot be reached, and the battery may heat seriously. Do not reach the maximum power at the same time
Power introduction
The basic version is PD100W output with a DC port. The expansion module can add two high-power C ports, the total power of Type-C can reach 300W, and support DC port output.
Battery installation and assembly
The battery box adopts a weld-free structure, which can directly install the battery without welding. If the battery is damaged, other batteries can be replaced by themselves. Among them, 18650 we use a high gold-plated battery box, which can output large current for a long time without heating. Use a screwdriver to fix the device during assembly.
The new 5389 details page has added an image update: Content: The new 5389 is the ip5389-i2c version, and the Apple port has no actual function. Therefore, the current shipped version does not have an Apple port, and this position is empty, as shown in the picture. If you want to use an Apple port or mind not taking it, please do not take it
Note: Only ternary lithium batteries can be used, and lithium iron batteries are not supported.
