At 4ft, it just doesn’t reach as far as I wanted. The only gripe I have is that the cable is a bit short. This laptop charger works well for my needs. USB output: 5V 2.1A, 5V 1A Tip details and compatible brands: Tip Once you have the correct tip, connect it to the end of the cable and plug in. All you need to do is find the voltage and current on your original charger, and cross reference this along with your laptop’s brand to the data sheet. This charger comes with 14 ‘tips’ and a data sheet to help you locate the correct connection and voltage for your device. The ZOZO 12V Universal Laptop Charger is well built and suitable for most laptop brands. Let’s take a look at the 12v laptop charger that I have:
So even though I have a 1000W pure sine inverter in my van, still wanted something that was efficient (and convenient) for charging my laptop. Also, if you leave your inverter switched on, even when it’s not charging your laptop, it is still draining power from your battery. In each of these steps, there’s a power loss. An inverter steps up your 12V to 220V (or 110V), and then the laptop charger will step the power back down to 18.5V, 19V, 20V etc. depending on your laptop. In some cases, a cheap MSW inverter will cause your laptop screen to flicker when plugged in, which pretty much renders your laptop useless, so these aren’t a practical solution for laptops.Ī pure sine wave inverter works just fine with laptops, but even so, inverters aren’t very efficient for charging laptops. Unfortunately, the cheap inverters are almost always modified sine wave inverters, and this is a problem when it comes to laptops. 1 is modified sine wave (MSW), which is not the same as mains power in your home, and 2 is pure sine wave (PSW) which is the ‘clean’ type of AC power, similar to what you have at home. Inverters change 12V DC to 220vAC (110V in some countries), and do this in one of two ways. I can now power my laptop straight from my leisure batteries without the use of my inverter, which is more energy efficient and a lot more convenient. I’ve had it for a couple of months now, and use it every single day.
So I took the plunge and bought it off Amazon. It looked well built, had 90W of power output (more than enough for most laptops), plugs straight into a cigarette lighter socket and even has 2 USB sockets to power tablets, phones or whatever other 5V USB device you might have. This charger certainly seemed like it fit the bill. After a lot of research, I found a Universal 12V laptop charger (Amazon). I started digging, reading many forums, and even learning about DC-DC converters to get a better understanding what it was that I needed. Quality – it needed to power my laptop without it interfering with my audio equipment.But still powerful enough to charge my laptop quickly.Plugs directly into a cigarette lighter socket (I have multiple in my van).
12V to 19V laptop charger (for my Acer Aspire laptop).I certainly can use my 1000W inverter, and plug my original laptop charger into it, but this is overkill and not very energy efficient, so I started looking into powering a laptop from a car battery (or leisure batteries in my case). I also wanted a laptop charger that runs without the use of my inverter, so needed one that runs directly off 12V, using the cigarette lighter socket.
