I bought them as quick chargers for iPads. It fulfills its purpose and I measured a peak consumption of up to 27W and a continuous charging power of up to 18W on the iPad mini 6. On the other hand, it' s not worth much for the price. It is 2x more expensive than 20W Apple or third party sources with the same or higher power, for example Samsung 45W, which also has a USB-C 5A cable in the package, is capable of PPSka* and costs half as much. It just doesn' t have a replaceable plug and can' t be grounded, which in turn is quite a good feature of the Apple power supply (10/12/29/30/35/61/67/87/96/140 W). Just for fun. When I ordered two sources, each was a different revision. One was A1882 and the other A2164. They are the same size, slightly different in weight. A2164 weighs 111.71g, A1882 weighs 118.52g. What is also different are the output voltages, the A2164 has them a little lower, especially on the 9V and 15V outputs, which is less of a problem, for example, when charging powerbanks, which either actively reduce consumption when the voltage drops (detection of a weak source / poor-quality cable), or have fixed current limit, for example 2A. For example, with AlzaPower 20,000 mAh, because of this, the charging power only reaches 15W instead of the limit of 18-19W. Results of empty A2164: 5.15V; 8.87V; 14.81 V; 20.07V. A1882: 5.21V; 9.02V; 15.01 V ; 20.12 V For me, I would give the A2164 variant a rating of 2.5 / 5 and the A1882 variant 3.5 / 5, so on average 3 / 5. Apple generally has good quality power supplies and has premium components in them that last a long time, but the low voltage at 9V and You may be wondering why such a long review for the charger, but since I' m already measuring it for my bachelor' s degree, why not share the info: ) * PPS is a programmable power supply and is used by many Android phones for fast charging. The power supply can vary the voltage in 0.02V steps to charge faster, demand higher currents at lower voltages and bypass the phone' s charging circuit to avoid heating the battery: ) Without it, phones have to switch to 9V and usually only charge moderately fast, for example around 15 - 27W
