If the characteristics of the coffee beans are such a refreshing and clear acid, and the acid has a mellow flavor, the siphon cooking method can make the characteristics of the coffee betterthe flannel filter can effectively block the powder in coffeewhen the water rises during boiling, the black coffee is reduced, step by step, in the hands of the coffee makerthe increasing base is sturdy and stablethere are also many people who like the siphonic cooking method with a little sense of laboratory precisionthe siphon-style coffee is loved by many coffee fanscompared to the italian coffee, which is often necessary to hand over part of the process to a machinethe lower pot scale can give you a clear multiplayer capacity1"weight: about 2000g packing includes:1 x bracket 1 x upper limb 1 x lower limb 1 x cover (seat) 1 x alcohol stove 1 x windshield 1 x original filter cloth (mesh)1 x coffee stirring spoonplease note:1specification:material: stainless steel + glasssize: 36please understand that colors may exist chromatic aberrationsiphonic coffee seems to be more suitable for people who like to do their own diyplease allow 1-3cm error due to manual measurement

App control method: compared with other ordinary refrigerators, in addition to the button control of the body, the bluetooth app method can be selected, and the mobile phonesafety and energy saving: with voltage protection, if the voltage is too low, the car refrigerator will automatically cut off the connection to prevent the battery from running outfast cooling: using a powerful compressor, the portable refrigerator runs the fast freezing function, at an ambient temperature of 25°c, the refrigerator can cool down from 25°c to 0°c in 25 minutes (a bottle of water takes 478inchplease note15l can only be used in the carfeature:- the refrigerator is made of environmentally friendly abs+pp material, no pollution, low noise, long service life, low consumption and good stability5 hours to freeze)- power-off heat preservation: under the condition of ambient temperature of 25°c, it can be kept at -18°c to 0°c for 2 hoursmaximum power 45w, high performance, 30% energy saving8 磅normal0specification:name portable car refrigeratormaterialabs+pphousehold chargingac110-240v wide voltage (optional)car chargerdc12/24v universalpower consumption45wtemperature range- 20 ℃ ~ 20 ℃ / - 4 ℉ ~ 68 ℉battery protectionwith voltage protectionapp bluetooth controloptionalnoise45dbcontrol panellcd panelweight11/12/15kgsize:15l: 570*320*260mm/2260inch30l: 575*365*350mm/261111microsoftinternetexplorer402documentnotspecified724inch20l: 570*320*320mm/22

the reliable driving method of the complete two-piece half-bridge driver chip minimizes the switching loss of the mosfetit can quickly brake the motorthis can make the car can start quickly and kill the car quicklythis driver also has a braking function that can quickly brake the motor, the braking is rapid, the braking is obvious, and the operation is simple to achieve this functionthe mosfet adopts n-channel irf3205 mosfet, uses two dedicated half-bridge driver chips, and uses a bootstrap capacitor for the upper tube, so that the upper tube has enough driving voltage, which can quickly turn on the mosfet channel and improve the acceleration curvature of the motorthe driver can work at 0%-99% pwm modulation duty cycle, so that the motor can get enough driving voltagethe driver is superior to the complex problem of timing coordination and complementary driving problems in the integrated power chip solution with low power margin and other half-bridge combination solutioncan withstand large current overload, the maximum current can reach 30athe mosfet driver chip has its own hardware braking function and power feedback functionthe driver is composed of two complete half-bridge driver chips + extremely low internal resistance n-channel mosfetfeature:the performance of this driver is not comparable to those of l298 motor driver chipsimprove power utilizationthis driver pays attention to current and efficiency, and effectively exerts motor power and battery life
