Main Features: Check Charging Speed: test & save history, compare other charger. Charger Testing help you to compare charging speed when you use different power source. Wait a few minutes and you will know how fast your battery is charged. App very easy to use, plugin charging cable and start testing.When I check the power solders though, I do get a reading of voltage as I do on many other parts of the board. My problem is that the computer will not power up at all, even bridging the power solders. But in recent years, counterfeit electronics have surpassed nearly all other categories of counterfeit goods by dollar value, and Apple, being the de facto high-end electronics manufacturer, makes for a prime target.I have an a1181 model macbook. It happens in every industry, from clothes to food to tech. That’s why it’s so important to be careful about picking the right charger for MacBook Pro.Anywhere premium products are produced, there are unsavory folks trying to make a quick buck selling cheap knockoffs.Obviously, anything that advertises itself as third party should be taken as such. Of course, the easiest thing to do is make sure you buy your charger from a trusted source.At Beetstech, we make sure everything we send out is thoroughly tested before it reaches the customer. It used to be that knockoffs were easy to spot. Recently, these counterfeiters have started doing a pretty good job replicating Apple’s exterior design to look quite a bit like the OEM parts they are trying to replace. Using a USB-C charger that provides at least the same wattage as the power supply.But you’d never be caught buying counterfeit electronics, because you can tell the difference, can’t you?One of the most common Apple products, where knockoffs are passed as OEM, are MagSafe adapters. There was even a huge controversy a few years ago where Amazon was selling knockoffs as OEM Amazon has since fixed that particular issue, but knockoffs are still out there, and detecting them is getting harder.If you’re looking to buy a replacement charger and want to know if the one you are getting is real, it may be hard to tell.
OEM MagSafe LEDs are turned on by the actual computer. If the LED turns on right away, or in less than one second, it’s definitely a fake. Luckily, there a few easy ways to tell a fake from the real thing, once you have them in your hands.The quickest way is to plug it into your MacBook. Notice the knockoff (bottom) has darker text.But let’s say you already bought one, or maybe you bought a MacBook secondhand and suspect it came with a less than reputable MagSafe. These differences can be hard to spot without a side by side comparison. Go to About this Mac>System Report>Hardware>Power, then scroll to the bottom. OEM The knockoff comes onSeveral sources online told me that you can also check the authenticity in the system information. I have seen some that have stayed on for close to five seconds, a sure sign they were fakes. This process takes a little over one second, causing a noticeable delay in the LED. The LED on fakes may also stay on after they unplugged. When it is satisfied everything is in order, it sends a signal to MagSafe internal chip to turn the LED on. One quick test is the weight. Often knockoffs will be lighter since they use cheaper smaller components. Again, the easiest way to know is holding a known OEM MagSafe in one hand and the suspect one in the other hand and comparing. This information is stored in a microchip in the MagSafe connector, so it may be the knockoff simply used the wrong one.There are a few other indicators that a MagSafe is not real. So, that’s something to watch for. One thing I have noticed is that a good knockoff may be labeled as a certain wattage, but the System recognized it as a different wattage. It is possible that the serial number doesn’t match anything, but since Apple has no way to search these serial numbers, I can not always recommend this as a reliable way to determine the authenticity of the MagSafe. Some knockoffs might not have this information, but sometimes good fakes do have some of the correct looking information that looks reliable to the untrained eye.

Often knockoffs will be lighter since they use cheaper smaller components. Not a huge difference, but it is noticeable.There are a few other indicators that a MagSafe is not real. The collapsible cord holder tabs can also be looser, or sometimes they can be harder to extend. This often leads to the seams being less-than-perfect. Apple has fairly strict manufacturing standards, while the cheap ones usually don’t. Not a huge difference, but it is noticeable.There also may be noticeable differences in the seams. Check Wattage Charger Cracked The EntireA lot more pressure was required to even crack the glue, and even then I had go along the seam and keep pulling glue apart. With the OEM charger, it was much more of a fight. Once it was cracked the entire thing came apart easily. I barely had to apply any pressure in order to crack the glue. This is where the answer to, “Does it really matter?” becomes most obvious.The first thing I noticed when taking these apart is how much easier the knockoff MagSafe came apart. Apple's cord-holding tabs fit snugly.Let’s get into the insides, the place where the differences become stark. The whole thing is encased in a copper sleeve with a protective tape underneath it. Apple’s MagSafe is extremely well protected. OEM MagSafe Knockoff ChargerNow that we are inside, the differences are clear from the start. Apple has taken the time to countersink their screws, where the knockoff’s don’t. Another small difference of note is the screws. Even if was made of metal (it’s not, it’s chromed plastic) it would not provide any connection to a ground from a wall outlet. We can also see that, sure enough, the ground post is not hooked to anything. This doesn’t seem to provide much of anything other than a little bit of extra weight. The knockoff has a small piece of cheap steel. It’s hard to tell, but to the right of the larger transformer (the big yellow tape covered one) is another covered piece: an internal processing chip that communicates with the laptop to decide which power setting to use.Then, there are the safety issues. The knockoff only has one, which is why it has a constant output of 20 volts. These two transformers provide higher and lower voltage. The main one is a bit larger, making it a bit more reliable. There are two transformers. OEM MagSafe Knockoff ChargerApple’s MagSafe is crammed full of components. It is required in Europe, and not having it can lead to higher costs from energy companies and a less-than-efficient conversion from AC to DC (the whole point of a MagSafe).When we flip these over, we can see even more problems. I’ve witnessed what happens when a resistor pops, and it’s not fun to see smoke and a funny smell coming from your electronics.There are also whole components missing some of them just provide more channels to keep the electricity in check, but a big one that is missing is the Power Factor Controller This device makes sure you are pulling the right type of power from your AC wall socket. Cutting these corners means there are more places where things can go wrong. The main capacitor in the knockoff is larger, but the rating is actually higher on the Apple OEM MagSafe. Even with the all the extra space the knockoff has, it’s harder to see any such safety line.In fact, there a few places where the solder just overlaps onto other components or comes dangerously close. You can see a clear line of delineation (starting in the bottom left corner and heading 45 degrees up) that keeps high and low voltage separate. On top of that, they have kept the proper distance for parts that should never touch. Also, despite having vastly more components, Apple has a more organized circuitry. Again, we see Apple using resistors with much higher ratings. They might be cheaper initially, but they will cost you more down the road.With macOS 10.
