The company claims that the new product has a unique structural design, the LED is fixed to the metal insert on the outside, and the inertia liquid is injected into the bulb to cool, so that a high-current drive can achieve higher brightness with only a few components.
It is understood that Switch's 75-watt replacement lamp has a power of 16 watts, using 10 LED chips, and the luminous flux reaches 1150 lumens; its warm white light color temperature is 2750K, and the color rendering index is 85. Calculated according to 3 small times per day, the life can be It has reached 18 years.
The company plans to offer neutral and warm white color temperatures for alternative lamps of 40 watts, 60 watts and 75 watts, and revealed that the retail price of a 60 watt replacement lamp is expected to be about $20.
Powerbanks are popular for charging smartphones and mobile tablet devices. A powerbank is a portable device that can supply power from its built-in batteries through a USB port. They usually recharge with USB power supply. Technically, a powerbank consists of rechargeable Lithium-ion or Lithium-Polymer batteries installed in a protective casing, guided by a printed circuit board (PCB) which provides various protective and safety measures. Due to its general purpose, powerbanks are also gaining popularity as a branding and promotional tool. Different brands and promotional companies use it as a promotional tool and provide a customized product.
Specifications:
Capacity in mAh: mAh stands for milli Ampere-hour and measures the amount of power flow that can be supplied by a certain powerbank at a specific voltage. Many manufacturers rate their products at 3.7 V, the voltage of cell(s) inside. Since USB outputs at 5 V, calculations at this voltage will yield a lower mAh number. For example, a battery pack advertised with a 3000 mAh capacity (at 3.7 V) will produce 2220 mAh at 5 V. Power losses due to efficiency of the charging circuitry also occur.
Simultaneous charging and discharging: need to specify if the powerbank can be used while it is charging.
Number of output USB ports: This specifies the number of devices that can be charged simultaneously.
Output current rating: This specifies the current rating that it can charge maximum. The higher the number, the better the powerbank. This can vary from output port to output port.
Input Current Rating: Input current rating is the amount of current the powerbank is able to draw at its maximum level while getting charged.
Safety Protections: Over Voltage Protection, Over Charge Protections, Over Current Protections, Over Heat Protections, Short-Circuit Protections and Over Discharge Protections are the common safety measures observed with standard powerbanks.
LED Indications: The Led glows as per indicating the amount of charging ability left with the powerbank.
