How do we turn the web into something other than a horrible advertising machine?
How do we turn the web into something other than a horrible advertising machine? I’m not sure it’s viable, in the mass market. You’re basically asking people to pay for stuff they can get for free by enduring ads. I think most will endure the ads.
Most of the content on the web is garbage. But people are happy to look at it, but are they happy to pay for it? Probably not.
At the moment, we’ve introduced the idea that software, and especially web sites should be free to use. I think that’s going to be a hard thing to overcome.
I think we’d probably need a well funded company to make alternatives. Say if Apple made a Facebook alternative, no ads, no tracking, but charged a yearly fee for use, could it succeed? Maybe, with Apple’s marketing etc, I think it’s viable, but I think free products would prevail.
I think also paid-for services introduce a level of service expectation that a lot of companies would not be comfortable with.
I think generally, the content isn’t good enough to charge for in most cases, but if it was, we’d need to work out a good micro-payment system, with actual money, not Bitcoin. I’m a software developer by profession, and I don’t use Bitcoin, outside of tech, nobody does. We’d need a proper micro-payment system, easy as pie to use, secure as hell. So if I’m reading a good article, I can give the writer 10 cents as easy as I can open a new tab.
That might work, but we’d need to work out a way where ultra-micro-payments can work, a Washington Post digital subscription is $2.50 a week, that’s a lot of articles, probably values a small article at less than 1 cent.
Startups battle over growing power bank rental services in China
At least 15 startups in China have joined in the competition for the growing domestic power bank rental services, among which three companies have landed a Series A round of funding worth hundreds of million yuan, reports the Beijing News.
Early this week, the Shenzhen-based Laidian Technology, a company offering power bank rental services, sued its counterpart Ankerbox over patents infringements, a signal of the intense competition behind the power bank sharing businesses in China.
Venture capital firms like IDG, Redpoint Ventures and GSR Ventures, together with tech giant Tencent, have reportedly already invested in startups focusing on power bank rentals.
In Beijing. Shared power bank devices can be seen in shopping malls and train stations. The power bank rental market covers three main areas.
The first kind, represented by Laidian Technology, enables users to rent power banks in one place and return them elsewhere. They are mostly available in major public venues like train stations, airports and hospitals.
A second option, offered by Ankerbox, mainly focuses on small places like café and bars. The power banks are movable.
The third option. With all power banks installed on desks.

How to use it
Through all three, users can charge their phones after paying by scanning a barcode. Generally, it’s free for up to an hour, and then costs one yuan per hour for extra time.
Currently, profits through power banks come through rentals, deposits and advertising revenues, reports the Beijing News.
So far the concept is in its infancy. However, their popularity is said to be growing. “It’s the same with the bike-sharing system, we must provide a certain scale of shared power banks at first, so as to change people’s habits of renting power banks.” said Tang Yongbo, founder of Xiaodian.
“I haven’t considered how to make a profit. As an infrastructure provider, I think the scale and density of our shared power banks come first as a basis.” Tang added.
Estimates suggest the power bank sharing sector could eventually develop into a ten-billion-yuan business.
Sharing power bank – another sharing economy platform?
In a world where there’s an app for everything and everyone. Sharing economy has been one of the terms that keep popping up – as if creating a short-term rental service was the solution for everything (there are even apps that let you rent other app sharing services for a small period – Sharinception). There’s a sharing economy platform for everything. And the most recent one (or the one that we’ll discuss) is the powerbank sharing economy. Shared power bank has entered the investment field of new market.
What is sharing power bank ?
A shared-charged economy platform is a digital service. Which allows you to rent portable phone chargers, for a short duration of time and pay-as-you-go. Amidst other existing services (and ways to do it), let’s use Dudu as an example.
Dudu is a Swedish app, that allows you to take a Dudu (power bank） from any of their different stations. Charge your phone while you are on the go, and return them at your station of preference.
Why is sharing power bank important?
We all have a phone charger, and there are many portable charger options, so why renting one? The oversimplified answer is life doesn’t really go as planned. In theory, you charge your phone at home, you play around with it, and when the battery runs out, then you charge it again. Sounds easy, right?
In real life, sometimes you forget to charge your phone the night before, or you don’t go around with your charger everywhere, or the bartender feels moody and does not want to be bothered to take a look at your phone. Also, is it even possible to carry your power bank fully charged when you need it?
Well, in our experience these events happen more often than what we are willing to admit they do, so instead of asking ourselves whether we should or not rent a power bank, we would like to ask if it is worth it to go through low-battery system when you can rent a phone charger?
The final percentage
Sharing power bank is the ugly little duck of shared economies. It doesn’t sound sexy, it seems unnecessary, and it lacks the glamour of other platforms, but in reality, powerbank sharing serves a universal purpose, helping people when life does not go as planned.
The news is saying airport charging stations hack your phone, but if they’re just charging ports, how can they hack your phone, and why is the airport installing data cables as charging stations?
They’re using USB slots for charging because that’s the one cable everybody has for charging their phone. That’s the cable you’ve got in your carry-on bag. Never mind what the other end of the cable is, be it a micro-B or nano-B or whatever the heck they call tiny connectors these days. the other end is a regular old USB-A. It would plug into your computer in a pinch to charge your phone or, more likely, you use it to plug into the charger that came with the phone.
There’s nothing sinister about the airport doing this. Yes, with a standard AC plug, you could use your phone’s actual charger, but this way, you only need the cable, and a rack of USB ports takes up less space.
charge station for power bank rental
Yes, it would be possible for someone who had access to the airport’s wiring infrastructure and the time to do so to require those ports as full-on data ports and theoretically suck your info off your phone. But they really would have to change the wiring in the wall to do that. Or, they could just hide a small computer under a shelf, and place an innocuous-looking rack of USB ports on the top side of the shelf, in such a way that it looks like the airport installed it. That’s how the Mission: Impossible guys would do it.
The solution to that would be to use only those ports that look like fixed installations. Things that are built into the wall are much harder to hack.
Can you use a vape while it’s charging on a portable power bank? Most modern vapes have a passthrough to allow this. They have had this for several years. Can you use them while charging, yes. I would though caution against this though. When you are charging and using the vape as with any battery it will heat up the battery. The same as with a smartphone using it while charging. Let it charge and leave it alone. Buy you two vapes if need be.
One to use while the other charges. I have many over the years and only use regular 18650 and 18350 battery vapes now. I have several batteries that while I use one the others are on charge. Charging the vape on a portable power bank or from a wall or car charger makes no difference, it will charge and with the pass through it can also be used.
power bank station
Generally, it depends on the battery used in your vape. If your battery model supports “pass-through” charging, meaning that charging port is other than output port, this means that battery could be used during charging (i.e you can vape).
For other type of the batteries, you have to disassemble battery to charge and makes vape unusable to use. The “pass-through” feature, noted above, is only the feature which does not not indicate that battery has good or bad quality.
Usually yes, no problem, providing there is some charge left in the battery. Of course it will take a lot longer to charge while using it. You would be far better off

Power banks are devices that are used to charge mobile phones, tablets, laptops, mp3 players and mp4 players anytime and anywhere. With the use we subject are devices to, it is important to have a power bank to be able to keep these devices up and running all the time.
Power banks can give you uninterrupted access to play games on your laptops. Instant message on the internet, use social networking platforms and book airline, train and bus tickets at the drop of a hat.
There are certain specifications that you ought to keep in mind before laying your hands on the ideal power bank for your need.
Grab a power bank that is double in battery capacity to be able to charge your mobile phone, tablet, laptop, mp3 player and mp4 player at least once. Today I will introduce you How Does a Power bank Work? To understand things a bit better, let’s take a look at a block diagram of how these devices work, after that we will see some of the major and minor components of it.
Schematic diagram of charging Treasure
Major components:
Moving on to the main question, How does a power bank work? To my knowledge all of these devices use Lithium Ion/Lithium Polymer battery as their power source, so in the inside they have these type of batteries. Remember this is the same type of battery that is inside of your phone, tablet, laptop or most of the portable devices that we use these days.
These cells are so popular and widespread due to their high weight to power ratio. Lithium batteries can provide about 300W per kg where the other ever popular lead acid can only do 180W per kg. So more power, less weight that’s what is needed on a portable device.
So we have got the battery for such devices, lithium ion or polymer. Now we need to make sure it can provide proper voltage and current to the device. Lithium cells has a nominal voltage of 3.7V and can go all the up to 4.2V while fully charged. But the USB ports that we use has 5V with strict regulation. So we need to change this cell voltage to 5V.
How can it be done?
Usually it is done by a boost converter that provides a steady 5V on its output regardless of the battery voltage being at 3.7V or 4.2V or anything in between them. If more than one cell is used. What I have seen is manufacturer uses them in parallel. So they can use the same circuit just have better service time. Although the one that I made, I used two 18650 cells in series and use a buck converter to lower the voltage to 5V. Either way output voltage is 5V, we got it on USB so we can charge any device. Another important thing about this boost converter is,
it usually limits the output current too, depending on the circuit it can provide different amount of current. In some cases, where it is suppose to charge a laptop however. The output voltage can be 12V or 19V depending on the model or depending on the device that it’s manufacturer is aiming at. So we have a power source inside and a circuit that can provide our desired voltage and current. Everything is fine so far but we need to charge this cell right?
So next part, charging the battery that is inside of them. Charging a lithium ion is a bit tricky. You have to make sure to put proper voltage and current in and change the charging profile. When necessary and you have to control the voltage otherwise it can blow up.
Lithium ion takes a steady/constant current up until they reach their 60-70% capacity then it charges at a constant voltage. Steadily declining the input current to them. So you need a charging circuit that have such ability. Also it is safe to use a charging current that is half of it’s amp-hour rating.
For smaller capacity power banks, usually an USB input is provided for charging it up. As smaller capacity devices have smaller cells it is easy to top them up with a smaller current from any USB port.
Larger capacity ones however include their own power brick or AC adapter with them to charge it from AC main line.
Now we have a working power bank that can take in power from USB or an AC adapter(similar one that is found with any phone, tablet or laptop, but might have a different output voltage). And charge a battery inside it and can power your device using that stored energy. Done? Not really, there are some more bits and pieces of stuffs in their. Let’s talk about them
Minor components
Usually these devices, or at-least the good ones have indicator that shows the battery percentage. So you can see how much power it has left or should you charge it or not. So we need a circuit that can sense the battery capacity . And show us by maybe a multi-color LED or maybe a bar graph or maybe with a LCD. Some of these devices have some built in meters for measuring voltage and current. Usually on the output section and they use LCD or LED display to show that. It without these circuits. The power bank will still work but they make stuffs a lot easier and more suitable for using.
There are some more circuit to ensure the safety of these devices, like temperature sensor or current sensor. What it does is while charging or supplying a load it keeps on checking. The battery or the circuit temperature to ensure that both of them are within their standard operating range. If something goes sideways it automatically turns itself off. They also measure output current too to see if the output current is within it’s limit, if not, it will automatically turn off.
Another protection circuit is there to protect the battery from going below a certain voltage level. Some battery has this protection built in but if it doesn’t have that circuit it might be added to the design to ensure good health of the battery.
This is pretty much how does a power bank work. But all the circuit blocks that I have mentioned here might not be available in many designs but reputed manufacturer will have them for sure.
There are huge amount of power banks available with many different capacities. And it is pretty overwhelming in most cases to select the perfect one. Yet simple advice go for the reputed manufacturer or the one with better warranty policy. Some power banks might come with torch light too, get them if you find it necessary.
Some power banks might have wireless or induction charging that uses different circuitry to make magnetic field to transfer power. This post is already kind of long so won’t get into details.
CAN I CHARGE MY POWER BANK USING THE MOBILE CHARGER?
It entirely depends on what your charger and powerbank are rated at, but: as a rule of thumb, if it uses USB, then the answer is very likely a yes. Keep in mind that, depending on the powerbank’s capacity and the phone charger’s rated output. The powerbank may place a load on the charger which the latter will not be able to fully satisfy safely:
power bank for rental station
the powerbank may not charge fully, the charger may become hot, or shut itself down due to overcurrent, and the charging process may take a very long time to complete (assuming it ever does). Cheap knock-off chargers that are known to catch fire may catch fire during this process. But the probability is generally low. 😉 Additional note: be aware that some very old chargers designed to work with Nokia feature-phones (the ones with physical keyboards) may use a micro-USB port. But actually deliver ~3.8V (which is not only incredibly insufficient, but also wildly outside of USB specification). This is due to the fact that Nokia has historically been caught using the micro-USB port as a feature port combo (back in the days when they still used 3.8V to charge their batteries). Notably, all of such chargers I’ve seen have the cable moulded into the charger.
