Previously, the charging head network dismantled a nut's 'battery-shaped battery' mobile power P100. On August 20th, the new product launch conference of the hammer brought you an upgraded version of this product, 'Battery-shaped battery' mobile Power supply (flashlight version), model P101.
The price of the product is 69RMB. From the appearance and functionality, there is a flashlight. Is there any more upgrade of the internal materials of the product? Let us take a look at it.
One, nut P101 mobile power appearance
The product packaging is still the original style, pure white; the front is printed with a red icon.
The word 'Smartisan' is printed on the side.
The product's parameters are printed on the lower back. Product model: P101; Input: 5V/1.5A; Output: 5V/1A; Battery type: 18650; Capacity 3350mAh; With flashlight function; Light source: 1W (max); : Beijing Hammer Digital Technology Co., Ltd.
A charging cable and instructions are included inside the box.
The included Type-C cable is about 20cm long and has a flat shape.
The size of the new mobile power supply is no different from the old one. The appearance of the battery, aluminum alloy casing, anodizing + matte treatment.
The word 'designed by SMARTISAN' is printed on the side of the product and a sling hole is designed at the top edge.
The charging interface is unchanged from the previous one, USB-A output interface, USB-C input interface, and power button and indicator.
The biggest change is at the top position, hiding the LED light inside the 'positive' of the battery, and perfectly integrating the function of the flashlight without destroying the original design concept of the product.
The state when the flashlight is turned on.
Use ChargerLAB POWER-Z KT001 to perform protocol detection on the output interface of the product, showing that only USB DCP protocol is supported.
Charging the LG G5 phone, the power can reach 6.3W or so.
Test the USB-C port with ChargerLAB POWER-Z KT001, no output.
Use the USB-C port of the mobile power supply and the USB-C to Lightning cable to charge the iPhone 7. There is no output. It can be seen that the USB-C port of this mobile power supply does not have an output function.
At the same time, use the C to C line to directly move the USB-C port of the mobile power supply and the Huawei mate 9 (with the OTG function), and the mobile phone charges the mobile power supply.
Second, the nut P101 mobile power dismantling
Firstly, it is removed from the head. Since the head cover of the mobile power supply is very tightly assembled with the aluminum alloy casing, it is not easy to disassemble, so it is directly deformed and violently opened.
After the cover is removed, there is also a plastic plate, which is fixed with two screws. The middle part is the LED lamp bead.
Continue to remove the outer plastic plate, expose the LED lamp beads and the fixed plate, also use two screws to fix.

The lamp bead is fixed by an aluminum substrate for heat dissipation. A soft rubber is attached to the back of the aluminum substrate.
Remove the battery core and the PCB board part, and fix the PCB board with plastic lining, so that the PCB board and the battery core are in a relatively stable state, which plays the role of shock absorption and fall prevention.
At the same time, a large amount of foam glue is attached to the side of the battery to further protect the battery core.
Adopting LG's 18650 battery core, the single-section capacity is 3350mAh, ensuring sufficient endurance.
The mobile power supply uses two PCB boards inside, which are connected by cable.

Using the British core IP5209 as the power master, this is a solution chip that integrates charging and discharging and has its own identification function. It supports 3A charging and 2.4A discharging, and the efficiency is up to 91%. It integrates 14Bit ADC and supports NTC thermal. The probe also provides power display support. The chip has high efficiency, mature and stable performance, which is used by many manufacturers.

Summary of charging head network disassembly
Nut 'Battery-shaped battery' mobile power (flashlight version) continues the overall style of the previous generation of products, and on this basis, the function of the flashlight is added, which can be used for emergency lighting. The internal structure and materials of the product have basically not changed. Imported LG's 3350mAh battery core and the main control of the British core.
However, in order to realize the function of the flashlight, an internal HT45R51 microcontroller is used.
At present, the hammer technology official website, with flashlight function version and flashlight function version are available for sale, the price difference is 20RMB. But which one is more worth buying may be a matter of opinion.
