Review on Multimeter Multifunctional Electrical Capacity Detector by Alex Maynard

I've always wanted to know how much current my chargers draw, but I didn't know how. Then I saw a video of this product on YouTube and decided to try it. I myself made sure that the amperage depends on 4 factors: 1) Charger. 2) cable 3) device 4) battery percentage. Battery. You may have a 5V/2.4A charger, but if your phone only requires 1 amp, use only 1 amp. You may have a tablet that requires those 2.4 amps, but if your cable is very cheap, generic, or inefficient, you're likely to have a large current drain. There are many opportunities. Typically, discharged batteries charge faster, and as they approach 100% they charge slower, typically over 70%. Also my Samsung A5 2016 charges faster when turned off as shown in the last photo. 5V/1.73A, about 9W. If you want it to charge fast, you need to connect to the outlet. 1.5V/1.32A is the maximum my Blackberry z10 can discharge from the charger. 5V/2.22A is the maximum that the Samsung Adaptive Fast Charger can deliver. . The Samsung charger is designed for a maximum voltage of 5V/2A, but seems to deliver more than advertised. Good for Samsung. 9V/1.60A is the maximum my A5 2016 will charge with the fast charger off. 14.4W, 5V/2.89A is the maximum I could discharge from a Maxboost car charger with both phones, which equates to a maximum current of 2.4A per output. Wonderful. This consumption is 14.5 watts. Also, the voltage didn't drop due to the outstanding current, so I have to say this is a great charger. Conclusion: I think this product is great. I use 3 months. No problem. You can also see how many mAh you have charged the battery. They have 7 functions. However. just great. Buy it and analyze how each charger, phone and cable works.
