Store Categories Store Categories Other Dual USB 5V 1A 2.1A Mobile Power Bank 18650 Battery Digital Charging Module Details Features 1. Use of high-quality materials, quality is guaranteed 2. Exquisite and compact appearance, beautiful arrangement of components 3. Charging comes with overcharge protection, over-discharge protection, over-current protection. 4. Stable output voltage and current, will not harm the user’s equipment. 5. Wide range of applications. Suitable for a variety of industrial DIY occasions Specification USB input: 5V1A USB output: 5V2.1A/5V1A (dual USB interface) Charging display: intelligent digital display Battery type: liquid lithium-ion battery (18650) Charging indication: charging display will come out IN letters Output load indication: long press the LED light button after connecting the load, the output starts, the display will show OUT letters and the relative output voltage and current 5V1A or 5V2.1A Attention Connect the B+ and B- of the boosted battery must not be connected to the reverse, the reverse must be burned! Can be connected to a lithium-ion battery can also be connected in parallel with a number of lithium-ion batteries Capacity does not exceed 200,000 mAh, voltage 3.-4.2V can be used Lithium positive electrode connected to B + lithium negative electrode connected to B- Frequently asked questions: 1. battery to use what kind of battery? Battery to flat 18650 battery, 65MM long, pointed battery can not be used. If the use of old batteries, different capacities, different brands can not be used, disassembled batteries to ensure that the voltage of each at least 3.5V or more, the voltage is too low, if you put it in the power (Note: you can also use lithium batteries, cell phone flat batteries). 2. How to distinguish between the battery + – pole and power box + – pole? General 18650 battery plane that end is the negative pole, there is a hole that end is positive. 3. Why is there no power output after installing the battery? After installing the battery, you have to plug in the 5V charger to activate it before you can use it. 4. Why does the charging cut off or shut down automatically? This is a disassembled battery has individual internal resistance is too large. Detect the pairing (of course, no instrument is unable to detect) or replace the battery can be new, in addition, try to use a good point of the line, the output current is too large will cause power failure protection, load current greater than 1A with 5V2.1A to charge will not be power failure protection. 5. Why charge to 99% charging can not be? If it is a new battery, the first time you install a good battery first discharge (i.e., charging the phone) to the inside of the power discharge shutdown, and then charge again to equalize the once can be charged to 100%. If it is an old battery is also the first discharge and then charge again, if it still does not work that is the internal resistance of the battery, capacity inconsistency caused. 6. Why is it that the display percentage is not allowed when the battery is just installed, and the battery is obviously only 50% of the power is installed to show 80%? The first time you install a good battery first discharge (i.e., charging the phone) to the inside of the power discharged shutdown, and then charge the power supply once equalized, the display percentage is accurate. All digital display power supply is like this. List 1 x Charging module Shipping Policy Payment Method Returns Policy Shipping Policy Payment Method This is the description of Payment Method.
