Today I will share with you a 3A charger that I like very much. The price is affordable and can be applied to all mobile phones. Let’s take a look at its appearance and performance test.
1.The appearance of the product
Different designs are used on the front and back sides to make the charger look more unique. The shell is smooth and suitable for customer-defined content.
High-quality ABS plastic, moderate in size, and smooth to the touch.
High-end gift box packaging is more suitable for retail.
3.Volume and weight parameters:
Charger length：46.12MM
Bottom charger width：44.80MM
Top of Charger width：44.52MM
Charger thickness：24.55mm
The three-dimensional parameters of the charger are 46.12*44.52*24.55mm, the volume of the charger is about 50.4cm³, and the maximum output is 15W, and the power density is about 0.30W/cm³.
Product net weight 39G
List of internal dismantling structures
PCB length：39.48MM
PCB width：36.26MM
PCB thickness：18.48MM
5.Compatibility and functional testing
Real machine charging test
The voltage is 4.633V, the current is 3A, the power is 13.899W,
Place it at a high temperature of 55 degrees and a low temperature of minus 20 degrees for two hours each. After taking it out, check that the product has not melted or cracked.
Aging test: Work continuously for 4 hours under the load of 3A current, there is no under-voltage or under-current, over-voltage or over-current. After working for 4 hours, the surface temperature of the charger is about 50 degrees, and it is not hot .
Evaluation summary
In terms of appearance, this charger has a very unique design, which is about the same size as Apple’s 20W PD charger. Performance supports 3A charging, which is basically suitable for all mobile phones. The size of the product is also relatively small, not heavy, and easy to carry. For small partners who usually travel a lot, using this charger as a spare accessory is a very good choice.
