Experience and Summary
The power output and temperature of the "Bess GaN5 Pro GaN Light and Thin Fast Charging Charger 65W" are both normal dual port GaN fast charging heads, and the core charm is in shape (nonsense).
It looks like a plump M2 SSD case/lighter when coiled. Before use, I felt that the body radian was a waste of space. It turns out that it's really hard to pull the charger out of the socket without this radian.
Personally, the biggest regret is that it is too fat to make a fully stowed folding pin (the rotating shaft is too close to the inside), which causes the quick charger to occupy the socket position very much. It will occupy the right and left space and the right space at the same time when it is inserted in the normal row, which is more suitable for being a lone ranger.
In terms of equivalent exchange, the thickness of "Bess GaN5 Pro Gallium Nitride Light and Thin Quick Charging Charger 65W" enables it to adapt to the sockets in those tricky positions, which are blocked by furniture such as TV cabinet/desk, tea table/sofa, bedside table/bed, etc., which can revitalize a previously wasted socket (of course, it is OK to use row plug connection, and then ordinary chargers, which is not so elegant) 。
But in a reasonable way, I think it is more suitable to take it out for emergencies, Comfortable , like a power bank, it is stacked with the mobile phone, and it is not too inconvenient to hold it. If you put the ordinary charger in your pants pocket, the passer-by will stare at the unknown bulge on your thigh, which will achieve the same burning effect as the Snapdragon 888.
Similar "biscuit charging heads" are sold by OPPO and Huawei. The OPPO ultra-thin SUPERVAC super flash charge of 50W is now 189 yuan, and the 66W GaN ultra-thin charging head of Huawei is 199 yuan.
The original price of Beisi GaN5 Pro GaN Light and Thin Fast Charging Charger 65W is 199 yuan, while the official website received 169 yuan at the deadline, and it is also a 1A1C dual port+compatible PD fast charging. If there are requirements for the size or thickness of the charger, it is really one of the few choices.
