NICE-POWER DC Power Supply Variable 30V 10A, Adjustable Switching Regulated DC Bench Power Supply with Output Switch High Precision 4-Digit LED Display, Benchtop Lab Power Supplies with 5V/2A USB Port

Precise 4-digit LED Display, Auto Power Calculation: The NICE-POWER DC power supply variable is a professional switching power supply regulation device with a high resolution of 0.01V and 0.001A. The variable power supply features a big bright 4-digit LED display that shows the adjustable power supply output values of Voltage (V) / Current (A) / Power (W) in real-time. The high-definition backlit 4-digit LED display provides an accurate and clear readout for the voltage, current and power values even if you are in low-light condition
Output Switch Control: Sometimes we need to switch between different voltage or current outputs in experiments or work, but we often forget to turn off the output and causing damage to the load. The adjustable DC power supply OUTPUT key is designed to solve this problem, just with a single press of the added OUTPUT key, you can easily turn the output on or off. The required voltage and current can be adjusted without actual output power, which makes this benchtop DC power supply more secure and more energy saving. Also, you don't need to remove the load or turn off the power each time, making the variable DC power supply more convenient and efficient to use
Reliability and Safety: Safety is our priority, all lab power supplies are CE & FCC certified. The adjustable switching regulated power supply is built with premium electronic components and reliable circuit designs that include multiple protection functions, such as leakage, grounding terminal, over-voltage, over-current, over-power, over-load, over-temperature, short-circuit protection to ensure stable working performance and prolong the life of the adjustable DC power supply effectively. Kindly Remind -For safety considerations, the DC power supply comes with only 110V input which meets the US standard voltage. 220V input is NOT available for this bench power supply
5V 2A USB Port, Intelligent Cooling Fan: Complaining about mobile phones or repaired devices not being charged in time? The NICE-POWER adjustable DC power supply allows you to avoid this dilemma. The variable power supply has built-in 5V 2A USB charging interface which can quickly charge any USB devices anytime. The adjustable power supply features with intelligent temperature-controlled fan and heat sink for excellent heat dissipation when the working temperature of the switching power supply exceeds 122℉/50℃, greatly reduce working noise and improving the DC regulated power supplies working efficiency and lifespan
Compact Design, Lightweight and Portable: The DC voltage stabilized power supplies adopt stable vertical design with the shock-absorbing rubber feet on the bottom of bench supply, making it safer and more stable when using. The size of adjustable DC power supply is 8.4*3.3*5.5 inches and the lab power supply weighs only 2.6 lbs, which is very light and portable.

Beleeb C40 Adjustable Battery Charger 12V 24V 36V 48V 60V 72V, 16A Pulses of High-Voltage Battery Desulfator Maintainer with Smart Chip for Lead-Acid LiFePO4 Lithium Batteries BLB-C40

One is enough>> Not only does it charge 12V 24V batteries, but it can also be used as a 36V 48V battery charger and even a 60V 72V battery charger. Now you only need one charger to charge different batteries like SLA, AGM, GEL, lithium, LiFePO4, deep cycle battery. It can be used to charge car, motorcycle, vehicle, RV, ATV, SUV, Golf Cart, forklift, Marine, Boat.
Two charging modes>> Normal mode and “H” mode(pulse of high-voltage). Normal mode for daily charging, turn the AMPERE knob to set the charging rate, “HIGH” for an emergency quick charge. “H” mode for battery maintenance, “LOW” rate charging is recommended.
Intelligent charging program>> Be sure to choose the corresponding voltage to charge your batteries. The charger will automatically adjust the charging voltage and current according to the battery status. Constant current, constant voltage power supply for zero voltage charging for troubleshooting low voltage batteries or equalizing unbalanced battery system for longer battery life.
What is "H" mode>>"H" means pulse of high-voltage, A golf cart usually comes with 4 to 8 batteries. One of them can go bad at any time. It makes sense to want to keep or change just the bad one especially if you only need to use the cart on the weekends or save money. That's what "H" does,also known as EQUALIZING CHARGE
Connect it& Forget it>> Overload circuit breaker and automatic control chip give you full protection. Just plug it, charging your batteries 24/7 without worry. Please do not connect lithium LiFePO4 batteries without a BMS to the charger for a long time.
