A power supply or charger supplies current. Devices like mobile phones, tablets and laptops consume current and will take as much as they need. So if a product requires 2.1 amps, then the power supply should supply 2.1 amps or more. If the power supply provides more than 2.1 amps, the product will still only take 2.1 amps.
In a nutshell, the Amps rating on a power supply, charger or adapter explains the maximum amount of current that it can safely provide in an hour. Any amperage of charger rated above what's required for your device is safe to use with your device, providing the PSU voltage is the same as the input voltage or within a tolerance of 1 volt.
Computer Power supplies have outputs of +12V, -12V, +5V, -5V, +3.3V and a common ground. You should check the tag on the power supply carefully. The tag will list the Amps for each voltage. In my case I choose a Dell 350 Watt supply from an old server. This had 14 Amps on the +12V line and even more on the +5V line.
How many amps home appliances use depends a lot on the specific devices. For example, a house phone barely uses 0.1 amps whereas an electric clothes dryer could need 28.1 amps or more. How many amps does a fridge use? A fridge will often use around 18.3 amps to start up and around 6.7 amps after that.
With that in mind, voltage is the essential factor and again should be the same or within a tolerance of 1 volt. A full guide on the key details of any power supply, charger or adapter including voltage, amperage and wattage.

The global residential solar storage and inverter market is experiencing rapid expansion, with demand increasing by over 300% in the past three years. Home energy storage solutions now account for approximately 35% of all new residential solar installations worldwide. North America leads with 38% market share, driven by homeowner energy independence goals and federal tax credits that reduce total system costs by 26-30%. Europe follows with 32% market share, where standardized home storage designs have cut installation timelines by 55% compared to custom solutions. Asia-Pacific represents the fastest-growing region at 45% CAGR, with manufacturing innovations reducing system prices by 18% annually. Emerging markets are adopting residential storage for backup power and energy cost reduction, with typical payback periods of 4-7 years. Modern home installations now feature integrated systems with 10-30kWh capacity at costs below $700/kWh for complete residential energy solutions.
Technological advancements are dramatically improving home solar storage and inverter performance while reducing costs. Next-generation battery management systems maintain optimal performance with 40% less energy loss, extending battery lifespan to 15+ years. Standardized plug-and-play designs have reduced installation costs from $1,200/kW to $650/kW since 2022. Smart integration features now allow home systems to operate as virtual power plants, increasing homeowner savings by 35% through time-of-use optimization and grid services. Safety innovations including multi-stage protection and thermal management systems have reduced insurance premiums by 25% for solar storage installations. New modular designs enable capacity expansion through simple battery additions at just $600/kWh for incremental storage. These innovations have improved ROI significantly, with residential projects typically achieving payback in 5-8 years depending on local electricity rates and incentive programs. Recent pricing trends show standard home systems (5-10kWh) starting at $8,000 and premium systems (15-20kWh) from $12,000, with financing options available for homeowners.
