Charging treasure from the initial design is to charge the mobile phone.With the economic and social development, more and more electronic products, small electronic watches, laptops, seems to be inseparable from the charging treasure.People gradually found that small-capacity Charging treasure is not enough! Charging treasure capacity from 5000mAh, 8000mAh bass bass up, the interface is also more and more.
Back to the original design of Charging Po - to charge the phone now, handset manufacturers invariably set the phone's battery life in about ten hours, that is, you go out at 8 o'clock in the morning, home at 7 o'clock in the evening, the phone power is also almost see famous.
If you want to get off work, ask a few friends to gather, either rent a shared rechargeable treasure, or bring your own, so do not occupy the place of mini mobile power to become everyone's first choice, after all, 'convenient and safe onset of fast.'
Many domestic and foreign consumer digital brands have introduced their own single section 18650 mini mobile power, we selected from the dozens of four, through the dismantling of these four mobile power, open the industry truth.
These four mini mobile power are: Millet portable flashlight LPB01ZM, Nanfu Xiaojia frequency X35, AUKEY PB-T12, Cagle T09.
Millet LPB01ZM is the millet launched last year with a mini-mobile power flashlight function, flashlight support 11 files brightness, 360-degree rotation, the function is very practical and very powerful.
Nanfu Xiaojia X35 looks exactly like snickers, the use of shell spray process, bringing the skin-like feel, the main color is vibrant orange, shape, feel, perception are impeccable, but also one of the few available on the market Support 2A output mini mobile power.
Aukey PB-T12 is different from the general single mini mobile power supply, using the 26650 batteries, so the capacity can be 5000mAh, is also the only one of four models to support QC3.0 fast charge mini mobile power.
Kagel is the earliest launch of four mini mobile power supply, so the capacity is only 2200mAh, but remarkable in design, and has applied for the appearance of patents.
First, dismantling to see the inner beauty
1, millet LPB01ZM
Outer packaging, transparent shell. Cylindrical plastic shell, the tail is a sticker, above the rack hole.
The bottom of the sticker is a parameter, the manufacturer, from the logo to see that this is the production of purple rice in Jiangsu, model LPB01ZM. Name as: millet portable flashlight. With 3350mAh capacity lithium battery, the shape can be judged as a single 18650 battery, mobile 5V1A power supply provides input and output, the light source is 3W.
Two synthetic transparent plastic shell, a flashlight, a charging cable, a rubber strap, a manual.
The flashlight is made of aluminum, silver above, most of the location below the beige.
Front printed MI brand logo, parameters, manufacturers and other information.
The switch position affixed stickers, there are suggestions, three consecutive open SOS help function, click to exit the SOS mode, easy to remember operation.Start instructions stickers, which is a USB-A output port, a micro charge input port, A button
Press the button in the middle of a small light, and this button is the SOS function keys, 3-click to activate the SOS mode to facilitate emergency help.
The silver of the head accounts for a quarter, and the head part is also a sticker.
Looks like a lens, but also yellow water. The benefits of the lens is more easy to control the condenser, you can do smaller. Side of the cylinder to see the lens.
The button is recessed a little to avoid the possibility of accidental touch.
The silver part is twistable, that is dimmed, and the white part is clearly indicated.
First open the lens, you can directly pull it out.
The lens is an entire piece of plexiglass.
Light beads center, two screws, the other two holes is open circuit location.
Lamp beads, according to the official parameter is LUMILEDS 3W led lamp beads.
Cut directly.
Violent cut, part of the shell, aluminum or a little thickness.
Inside is a deep cover with buckle.
Cover inside the PCB, connect the battery, USB output.
The seat is the largest, accounting for half the PCB area.
Big picture, it should be the program SY6618.
This IC is estimated to be purple custom, silk screen ZMF1206USBN.
With a six-wire cable connected to the top of this PCB, the power out to the head of the LED, the control power supply are in 6 lines.
Look at the barrel, there is a PCB, just 6 lines welded on it.
The bottom of the battery has a plastic protective cover, neat nickel spot welding.
Battery side of the temperature probe, purple series have the same temperature control.
Six pins on the board.
Look at the 18650 battery-to-case ratio. Pink-purple battery, LG 3350mAh capacity.
There are gears, the circuit compartment has two black apron.
Circuit box can be directly twisted open, threaded. Circuit gear white gear, dimming by turning the dimming ring.
Circuit cartridge with the barrel is directly threaded installation, playing a little glue.
Destructive to open, to provide some reference, took out the lens, twist this seat can be.
The white accessory on the right covers the gear.
This white accessory is positioned above the gear.
PCB size smaller than 1 dollar coin.
This is a plastic soft plastic cover.
Inside the cover is the buttons and lights.
Inside the lid has a long thimble, touch the button inside.
The missing piece is where the dimmer comes in contact with the white gear and twisting the gear to dimming.
LED PCB removed.
gear.
Side to see is the encoder, not guess the dimming ring, dimming sound is from here.
LED location, with a lot of vias, to enhance heat dissipation.
Below the encoder is a gear.
All disassembled items.
