While the use of power bank source for power bank just how much you know? The use of portable charger should pay attention to what? Again there is a principle of what should have? Now due to the presence of large amounts of power bank is defective goods on the market, the security problem already moved on portable charger in the consideration of consumer use.
A high capacity power bank , not necessarily based on large capacity power bank , must want to have a short circuit, over charge, discharge, constant current, constant voltage protection measures such as design, USES the good battery, perfect circuit design and protection board design, should also have high performance power management technology, so as to guarantee the use effect and safety.
In simple terms, power bank is a collection of storage, booster, charging management, which integrates a portable device. Dielectric generally USES lithium electricity storage batteries, because lithium electric batteries, relatively small volume, large capacity, wide market circulation, moderate price, is widely used in digital products. Mobile power supply to the output power is must have the boost system, so that you can charge for other digital products, such as mobile phone, MP4, tablet PC, PSP and so on.

This is super cool, particularly if you’re going camping, hiking, working outside, or just on a trip. You can use solar power bank for any USB device, so yes, for your tablet, phone, or laptop even, and it’s the size of a smart phone. Basically one side of the device is a solar panel that uses the sun’s rays to collect and store a reserve power source. It’s constantly renewing so long as it’s in the sun so you can for instance place it on the dash of the car when you’re heading somewhere then slide a solar charger in your bag when you set off and you’re carrying a dependable back up source of power.
So, next time you’re watching your phone power off at the worst possible moment, think back to this moment when you learned about this awesome solution and think, did you grab power bank when you had the chance?

Among the entire power bank advertisements, manufacturers always use many specifications to describe their products’ advantages. Consumers are so hardly to distinguish them from each other. In such cases, there are three aspects’ standards: capacity, conversion rate, self-discharge rate.
1. According to capacities, power banks can be classified to four grades, as emergency, business, quality, professional power banks. Lower than 2000mAh is emergency ones. 2000 to 4000mAh is business class and they can be used more than 300 times. Quality level is from 4000 to 6000mAh. 8000mAh capacity belongs to professional level. Large capacity power bank require 500 times more cycle life.
2. As to conversion rate, it can be divided into general, intermediate, advanced, super four levels. The relative conversion rates are 60%, 60-80%, 80-90%, over 90%. In the circuit design, the general level is non-synchronous rectification. The other three levels are synchronous rectification.
3. As per self-discharge rate, it can be identified as general quality, good quality, excellent quality. The general quality is with high self-discharge rate, over 1% each day; the self-discharge rate of good quality is 0.4 to 1% each day; excellent quality self-discharge rate is very low, less than 0.4% each day. The lower self-discharge rate means stronger power hold ability. It is decided by the quality of batteries and circuit design.
Power bank mainly consists of lithium battery, control panel and PCB circuit board which determines the quality of power bank. If a power bank has a well-designed PCB circuit board and outstanding cell and strong control panel, then it can be said to be qualified.
Absolutely, customers cannot know the condition of the inner construction but we can still choose a proper power bank for mobile phones. Then let me tell you some parameters.
First, the cell, which mainly includes lithium polymer battery and 18650 lithium battery. Lithium polymer battery is a pasty battery and can be made into any kinds of shapes. The package of lithium polymer battery is beautiful, fashionable and safe, but high rate of burning and blown package. 18650 lithium battery is liquid. 18 and 65 are size of the cell and 0 means it is columned and its largest capacity can be 3000mah which can be easily exploded.
Second, the control panel. It is for the automatical regulation of over-charge, over-discharge when is is being charged and turn off automatically when it is full charged.
Third, the appearance, which is somehow the first consideration of someone and can give us fun.
Seriously, how is this not alr
A selfie stick, also known as a selfie monopod or simply a monopod, is a handheld monopod device that holds a phone or camera at the end in order to take selfies from greater distances to produce better and more diversified selfies. There are several varieties of selfie stick to meet your every need- selfie stick with blue tooth, selfie stick for iphone, selfie stick for android, monopods for cameras, selfie stick with mirror, and more.
The selfie stick finds its origins in Asia and has just emerged over the past few years. A selfie is simple a photo of a person that has been taken by that same person- think of it as a self-portrait. While self- portraits and self- depictions have been around nearly forever, it is the rise of social media that has made the selfie a part of daily life. Now, selfies are popping up everywhere and of everyone. But, of course, the selfie has its photographic limitations- awkward angles, limitations to background and number of people in the picture, no full body images. Luckily, the trend that has so quickly spread across Asia has quickly evolved the selfie in ways previously unimaginable. The selfie stick allows for scenery, additional individuals, and more all because of the extended reach that the camera stick provides. Monopods for cameras means that people can really have it all- with the selfie stick, people can take their own picture and have it be of high quality as well.
Selfie Camera Stick has one sole mission: innovating the world of selfie photography to allow for people to produce great pictures and memories with their selfie stick. We offer information about the selfie stick, tips on how to look good in a selfie and improve your photo skills, and a place to view selfies taken with the selfie stick and share your own, along with being the top source to buy selfie stick and selfie monopods.
