Method/Steps Step by Step Reading 1/5 First, remove the mobile power supplySolder two 10cm wires to the positive terminal and one 10cm wire to the negative terminal (in order to save materials and reduce losses). Reinstall it in the battery case after welding. Adjust the led light position.
Manual Geng self-made charging treasure may be put into production? In the video of Manual Geng, you can see that the charging treasure made by manual Geng can be used outdoors. And the power bank, handmade by Geng, can power a running TV. In addition, the power bank can also power a washing machine andAnd can ensure the continuous operation of the washing machine.
The second point, the charging time is too long; Under normal circumstances, the charging treasure can be filled with 2 to 3 hours, like this giant charging treasure, it takes at least two to three days to charge a charge, the charging time is so long, it is better to charge yourself directly at home. Therefore, such a bullshit and useless invention completely deviates from the essence of the charging treasure. If you use it, you're paying an IQ tax.
Material millet charging treasure DIY kit, then buy 18650 lithium battery, wire several. Tools: Electric soldering iron, solder. Weld the batteries in parallelBattery box, the battery output line is welded on the booster plate (PS: be sure to pay attention to the positive and negative poles, otherwise the booster plate will be wasted). Then just put the shell on.
The large charging treasure made by Geng is a large flat battery pack similar to a battery purchased, and then modified, and the external frame and input and output interfaces are connected, so as to form a charging treasure.
For example, the memory module at layers 6 to 10 is PCFor B design, it is better to choose 10/20mil (drill/pad) pass hole, and for some high-density small-size boards, you can also try to use 8/18Mil pass hole. Under the current technical conditions, it is difficult to use a smaller size of the hole (when the hole depth exceeds 6 times the diameter of the hole, it is impossible to ensure that the hole wall can be uniformly plated with copper); For the power supply or ground wire hole, you can consider using a larger size to reduce the impedance.
In the range of ravg 0~0.08 m, the output power increases first and then decreases with the increase of coil turns; In ravg, it is 0.08~0In the range of 4 m, the output power decreases first and then increases and then decreases with the increase of the number of turns of the coil. For a fixed operating frequency, the quality factor Q mainly depends on the shape and size of the coil and the material used. Standard coil technologies (such as wire winding coils and PCB coils) generally specify quality factor values.
No matter what electronic products according to the reason the fewer PCB layers, the worse the electrical performance. On the contrary, the more PCB layers, the better the electrical performance. In electronic products, the more PCB substrate layers, the better. Because the more layers of the PCB board, the more solid the foundation of the motherboard, signalThere will be less interference between the electronic components on the motherboard to ensure that they work normally without interference in harsh environments, and the longer the service life.
Millet 55W vertical air-cooled wireless charging using PC flame retardant material plastic shell, fuselage edge clear end Angle arc transition, support board is black, base sandblasting treatment is gold. From the front, there is an LED indicator at the front of the base,The support plate is layered up and down, using different designs. Indicator light is green when working.
Mi 55W vertical air-cooled wireless charger is equipped with a special bracket, can be directly installed on the base, and is embedded, especially stable! It can be removed at any time when not in use, because it is specially configured for the Mi 10 Ultra, and it is generally not used.
Mi 9 Pro supports 55W vertical air-cooled wireless fast charging, but there will be no fan rotation during the charging process. This is normal, because during fast charging, the phone will emit some heat, but it will not be too high
