90W Universal Power Adapter 15-20v

This thing did exactly the trick for a 14 year old Acer Aspire. Works perfectly, no hassle.

I picked this up because it's always helpful to have a universal charger around, especially with different laptops around the house! The variety of connector tips was the main thing that caught my attention. The package is fairly compact, and everything is organized nicely. The charger itself is folded neatly in the box, and the different tips come together in a small, clear bag. There's also a user guide and a separate sheet that lists which tip matches certain laptop models. The power adapter feels and is not overly bulky, which is nice if you plan to keep it in a laptop bag. The cable length also seems reasonable for using it at a desk or outlet that isn't right next to you. Having so many tips included makes it pretty flexible for different devices. The guide shows which tip to use so you're not guessing. Once connected, it powers up my laptop without any issues and does what you'd expect from a replacement charger. The only small drawback is that with 17 different tips, it can take a minute to find the right one the first time. This is a handy option if you need a backup charger or something that can work with multiple laptops around the house!

Sufficiently Compatible Workable Solution that does its JOB electrifying technology appliance units as they should work in Voltage Wattage Amperage!

This unit is being used on an AS US all in one PC that lost its OEM charger and the universal tip adapters worked as intended, unlike some other that was purchased elsewhere and wasn't as ordered!

Review for ZOZO 90W 15V-20V, Model PA-3900-Z, ASIN B0132ST35Y INTRODUCTION & WHY I BOUGHT THIS ------------------------------------------------------------- I am an independent computer handyman and occasionally I encounter a laptop with a power problem that may or may not be caused by a faulty power adapter. A universal power adapter is a good tool to have so that I can verify that a new power adapter will solve the problem before buying one for my client. Sometimes the DC jack in the laptop is faulty, and in one Lenovo IdeaPad it was apparently the power circuitry on the motherboard that had gone bad, preventing the power adapter from powering the laptop or charging the battery, though the laptop was able to run on the battery after I charged it by alternative means (I had eliminated the power adapter and the DC jack as the problem by replacing both). I looked at several universal laptop chargers before selecting this one, and there was not much to distinguish any particular brand. The features I wanted were: 90W capacity (both in case I need that much power, and so that it will have more robust components), a wide voltage range (many have a range of only 18V-20V, which may be all I'll ever need, but I don't know), and a wide variety of charging tips (this has 16, many have 12). I had no clear reason to select this brand except that it seemed popular. DESCRIPTION & TESTING (this does work on Dells) ----------------------------------------------------------------------------- The seller's descriptions and photos all match the unit I received. The unit is made in China. The build quality seems as good as any power adapter. It looks and feels solid. It came in a small, sturdy cardboard box with a hinged lid which I will use as a storage box to keep the adapter and its parts tidy (7.5" x 5.7" x 1.9"). The tips were in a small ziplock bag. The DC cord has a Velcro strap attached but the AC cord has only a twist tie. I added my own Velcro strap. The DC tips are imprinted with both the output voltage and with the M-number, which can be used to look up the tip in the reference table included in the box. The tips fit very securely on the DC cord using a 3-prong connector, and so far they have fit the laptops perfectly (as well as the originals). The power brick is about a typical size and weight for a cheap 90W adapter. It has a green LED to indicate that it is receiving power. The AC cord fits very securely in the power brick. It is 6ft in length, which is fine, but the DC cord is only 45 inches, which is rather short. I do not anticipate this being a problem for me since I will not be using this adapter often or long term, and so the inconvenience will be minimal. However, if you intend to use this unit as your primary power source, you may find the DC cord to be too short if you want the power brick on the floor rather than on the desk with the laptop. A benefit of the short cord for people like me, though, is that it will make the cord quicker to bundle up after use, and the unit easier to fit in my tool box. I have tested this adapter so far on an Acer Aspire M5, three different HP Pavilions, a Gateway NV79, and four different Dell Inspirons (15 2558 from 2016, 15R-5521 from 2013, 1545 from 2010, E1505 from 2006). I will continue to test it on laptops that I encounter and update this review if I run into problems. So far it has functioned perfectly, being able to power the laptops and charge their batteries. I have heard that Dell laptops often reject non-Dell power adapters. I do not know if this is true, but it is not true of this particular adapter. I have not had the opportunity to run this adapter at its full capacity to see how hot it gets. I did just stress test it on the Gateway NV79 (65W) I am using to compose this review, using OCCT's power supply stress test (which runs both the CPU and GPU at max stress to consume as much power as possible), while also charging the battery. I ran the stress test for 20 minutes with the power adapter sitting on a carpeted floor. It became quite warm, but not more than I was comfortable with, and not nearly what I would call hot. During normal, light use of this laptop, the adapter becomes only mildly warm. Keep in mind that if you have the adapter under blankets or other insulators, it will likely build up much more heat. Allow your electronics some ventilation. LOCATING POWER REQUIREMENTS LABELS ---------------------------------------------------------------------- If you do not see a power requirements label on the bottom of a laptop, check under the battery. One HP Pavilion had that information, as well as laptop model information, inside the battery compartment. PROS ---------- - Wide voltage range and tip variety. - Seems well constructed and plugs fit securely. - So far the adapter seems reasonably power efficient judging by the heat output (I have not tested a full 90W draw, however). - Includes a Velcro strap for the DC cord to keep it coiled up. CONS ---------- - The DC cord (the one that connects to the laptop) is quite short at under 4ft, but as a diagnostics tool this may be a benefit due to its compactness. - I would like to see a Velcro strap on the AC cord (only the DC cord has one - the AC cord has only a twist tie).

I was panicking for a second because none of the plugs were a good match. The only one which worked stuck out too much, which I wasn't expecting with the variety of plugs included, I thought I would find a better match. I needed to replace the original power cord which came with my laptop since it broke where it connected to the plug which plugs into the laptop, which is a common fail area. I've now repaired two cords with the same failures with Sugru, the moldable clay glue. After using one of those past power cords extensively after the Sugru repair, it never failed again, so, the failure is not based on wear and tear, but on the actual plastic cord coating being too short and pulling out of the manifold/case at that spot. Will the same thing happen with this new power cord?? I don't know, but I will be pissed if it does. It does have a different design in that spot, but I don't know how functional that design is. After using this, I noticed a couple of things in the way my laptop performed. One, it appeared to take on more electrons which I could not get off, I figured this might have been true because the mouse pointer of my laptop started getting slippery (on the screen) and I couldn't even use the roller bar with it. Thank goodness, it all resolved by itself within just a few hours. The other thing I noticed is that my laptop battery charges faster and it even seems to hold the charge longer when unplugged. I wasn't expecting either of these two effects (on the mouse and the battery), but they do seem to be working for the good. The cord itself seems sturdy and heavy duty (stronger than the cord that came with my laptop), and I like that, too. Anyway, I don't really see why this power cord is so popular compared to the others, but I chose it in trust that it will perform, and I will probably try to use the remaining Sugru moldable glue as a safeguard on this cord, so I never run into that broken power cord problem again.

Works great for our purpose. Couldn't be happier with this purchase. Very quick shipping and delivery, too.

If you notice that your laptop's trackpad starts to feel sluggish or slow whenever it is plugged in to this charger, it's because this charger only has a 2-prong plug, so electrical noise will may be interfering with the touchpad's function. If you plan on using your laptop's touchpad whilst having it plugged in, I would suggest finding a charger that has a 3-prong plug (one with a grounding pin) so that it won't interfere with everyday use, but if you typically don't use your laptop while it's charging, or if you mainly use a separate mouse, this charger works great!

He estado leyendo reseñas de más usuarios y hubo uno en especifico que muestra que el voltaje que brinda es incorrecto, es más alto al que se indica y es por eso que causa mal funciones en equipos como me pasó a mí. ¿Por qué le doy tres estrellas? pienso que es un producto realmente útil si lo que quieres es poder cargar varias laptops que NO sean nuevas, es decir, que ya tengan algún daño en la batería o que directamente no te importe causar daños en la batería a un mediano plazo, y hay que TOMAR EN CUENTA que incluso puede causar algún corto circuito, deja un equipo inservible, y tener que recurrir a una reparación. Hay que tener en cuenta que el precio y la universalidad están bien pero puede causar daños a la batería del dispositivo, y al dispositivo en general, realmente es evidente al notar la sobrecarga en el malfuncionamiento del touchpad. Devolveré el producto y optaré por comprar uno original. Estas cosas siempre pasan con productos genéricos.
