Is a great variety of mobile power supply on the market, quality is uneven, the news media often reports mobile power of spontaneous combustion and explosive accident. Because of concerns about security issues, never buy mobile power supply, when buying a mobile phone before the businessman sent a mobile power supply, the look is not a product of the normal manufacturer, worried about security issues, just try to charge a, and the effect is a bit poor, afraid to use.
This time in the center of the trial found poetry levon mobile power supply "poem levon polymer mobile power supply 7800 hao" Ann, look at the inside of introduced just know,taobao agent originally, in addition to ordinary lithium batteries do mobile power supply and a lithium polymer batteries do mobile power supply. Baidu once, immediately find lithium polymer power compared with the ordinary lithium power supply, high security, and has a high energy density, miniaturization, ultra-thin, lightweight, many obvious advantages. This is in line with my request, and try to apply for the, very lucky, got the samples, thank you poem levon mobile power outlet and the trial center give me this opportunity to try.
The following are some of the trial product information:
[product name] : poetry levon polymer mobile power supply 7800 hao

The trial process and experience
A, appearance
1, packing: transparent plastic packaging, contracted style. The upper mounting design, convenient sales presentation.
Positive: brand logo, name of commodity, and anti-counterfeiting mark.
The opposite: the product function description, important, all kinds of certification marks and factory information. Seem to be very formal, those products will not identify these small workshops.
2, products and accessories, including a mobile power supply, a data line and a product specification, product warranty card. May be considered in order to save costs, does not include in the accessories have a charger, all kinds of common parts such as joint transform. You think accessories too little? For himself, the accessories are not problems, recharge mobile power can use mobile phones or other digital products charger, now the USB output interface are unified; Charging for mobile phones and digital products with their respective distribution of cable is ok, if matched those wasted instead, with more extra cost will be added on the price of the product. This is not a green design?
A: mobile power supply
Specification: 115.2 MM long, 59.2 MM wide, 12.3 MM thick.
Positive: the upper has a switch button and four power lights (25%, 50%, 75%, 50%), lower part only with a brand logo. Around the blue of the fuselage, match with white, the use of varnish, appears concise fashion, looks pretty fancy.
Ws: product description, indicate the type of the product, the current input voltage, output voltage and current, capacity, product certification and factory name.
Top: respectively is the USB output 1, Micro USB input port and USB output 2.
Details: fine workmanship, also do not see any burr on the side parts, closely seamless connection, pure color of the lacquer that bake.
B: accessories
Cable: 22.5 CM long, pure white, is the apple.
Second, the disassembly
A self-contained silk group, a crowbar, began to disassemble, see inside yes polymer battery is what appearance, really curious?
Apart from the bottom of the first started, pried open with a crowbar clip, only to find that the upper can't pry, watch carefully, die under the label, found there are two under the label notch, tore open label, unscrew the self-contained.
Open the rear cover, found with 3 m glue on the Bags,Shoes & Accessories both sides of the battery to get open with a crowbar. There is a circuit board and a polymer battery, ah, finally know the appearance of the battery. Is very thin?
Battery wrapped a layer of vacuum packaging, with fingerprint, a little soft, like a hard point of silly putty, break up with the hand, went into the shape.
Is the use of patch components, circuit boards, PCB line is neat, look just know is normal manufacturer production, and good quality of the interface.
This is to buy a mobile phone to send mobile power supply, box and power shell have no manufacturer information, on a full charge if need not, after a day, less than the power went out, just used once, mobile phone, once filled with the power went out. Now how to open and see what's inside, and contrast and pei polymer mobile power.
These are two: the inside of the accessories of mobile power supply contrast found that at a glance is polymer batteries, batteries, the size of the difference is obvious, on the right side of the poem levon polymer on size of mobile power supply; On the left side of the mobile power supply circuit board is the single side with a less known and inferior brand electronic components, the number is less, the arrangement is a bit crooked, poetry levon polymer mobile power supply circuit board on the right is double have electronic components, quantity is more obvious than on the left, and looks neat and beautiful; Interface, look poem levon polymer mobile power electricity better gloss of coating, the thickness is difference is not big. In general, or normal manufacturer product quality pass, with the rest assured.
You want serious look at this picture, opportunity is rare: of internal structure of polymer batteries, is to use material wrapped the layers, there is a little liquid, and smelling is acidic, don't know whether I, internal structure picture other trial report generally can't see, see after the batteries will hang up. Isn't me too explosive force, the poem of polymer mobile power supply after dismantling, batteries connect panels have a plus or minus two cables, including negative that root tightly wrapped with tape, the anode without tape wrapped, swinging connection after two pieces of metal to disconnect, use soldering iron can't weld fracture place, not on tin, the along while also didn't plug in, don't know what is the metal, only know must not iron or copper, otherwise it is easy to weld. In order to satisfy yourself and everyone's curiosity, cut open and see. Just can't use, it is a pity. Ok also use for a period of time, also take good photos, or you can't finish the report.
Three, use,
Recharge devices, as long as you press the power switch, can begin. If there is no rechargeable equipment connection, after a few seconds to electric power, usually don't have to worry about accidentally run into waste batteries and can effectively guarantee the safety use.
Mobile power battery is 100%, the recharge my cell phone can charge 3 times, mobile phone battery capacity is 1230 ma, charging 2 hours and 40 minutes or so every time can be filled.
Recharge mobile power supply, from zero to full phone charger with 1 a, will need about 6 hours, different charger is distinct.
Recharge my mobile phone and the IPOD at the same time, is it convenient?
Mobile phones and the charging at the same time. Need is important to note that the charging current is larger, the calorific value of mobile power supply will be bigger, indicator light there will be fever, pay attention to the location.
Special said this function: to 3 v to 5 v digital equipment for power supply. If the connection is not equipment of rechargeable batteries, open the power switch after a few seconds will automatically protect the electricity. At this moment can be twice the power switch, can force output. The power will not automatically disconnect. I at home a small Sports & Outdoor speaker tried USB power supply, it is completely feasible, it can bring a little in the outdoor sound, mobile power supply directly, is very convenient?
