How to charge a laptop without a light: power bank, station and car

Survive many years without light with the help of a serviceable battery and an adequate backup. But the great number “mA year” is not enough for a power bank: important energy reserves, output pressure and capacity.

Disassembled on butts from the battery. net. ua is the official supplier of battery packs and batteries for laptops in Ukraine.

How many years does the laptop last?.

Orientation formula: available energy (W year)? average consumption (W) \u003d working hours.

For example, 50 W year? 20 W? 2.5 years. Rating: brightness, video calls, games and battery power change the result.

For the power bank and station it is necessary to spend money on the re-creation and expansion of the device. And 65 W per charge is the maximum power, and not the constant acceleration of the laptop.

Turn the rose over for now.

USB-C. The laptop can support charging through the selected port. Dzherelo life – USB Power Delivery with the required profile and tension not lower than recommended for the model. The cable also supports the following: for a standard USB-C PD over 60 W, a 5 A cable with e-marker is required.

Round or branded plug. The simplest option is a station socket and a small living block. It is possible to use a DC output or a special converter if you need to check the voltage, polarity, plug and recognition of the adapter. The nozzle itself is not enough.

How many charges are there to reserve?.

Power bank for 20,000 mA per year at a nominal voltage of the elements 3.7 V may be 74 W per year, at 27,000 mA per year – close to 100 W per year. More precisely, look for the meaning on the body.

For a laptop battery with a capacity of 55 W per year, if you consider 30% of the total costs, a power bank at 74 W per year will give about one full charge, and for 100 W per year – 1–1.5 charges.

For these very minds, a station with 256 W per year lasts for about three charges, for 500 W per year - for six, and for 1000 W per year - for 12–13.

Guidelines for charging your laptop without using it for an hour. Real expenses lie in possession; The inverter robot shaft also wastes energy.

The transition from 3.7 to 20 V does not “consume” energy on its own. A part is spent under the hour of reconversion, so a year for different voltages cannot be directly accounted for.

Which method to select (for most selections).

Well, among the main ones you can see:.

– Station and living unit: turn it over to see if there is any pressure on the AC output. Since the laptop supports USB-C PD, direct connection to the station's output port reduces costs;

– Powerbank from PD: check the strength of a specific exit. A weak power bank for your phone may not start charging or you won’t be able to support it under pressure;

– Car: suitable car adapter, USB-C PD charging or inverter from power supply unit. Respect the limit of the car socket and do not discharge the starter battery while parked..

For multi-port chargers and power banks, check how the power is distributed between devices. The writing “100 W” may mean the voltage limit, and not the tension of the skin outlet.

After connecting your phone to your laptop, you may lose less money needed for work. Before connecting, test your combination: power supply, laptop, cable and accessories.

How to stretch the charge.

Before connecting, charge the laptop and backup battery. Since autonomy requires 100%, change the charge limit settings immediately.

Change brightness, turn on energy saving, turn off the keyboard backlight and remove unnecessary USB devices. It is better to schedule important calculations and updates for an hour from life.

Do you need a new battery and a spare charger?.

Another unit is handy for the office or backpack, but during the hour of switching off you also need a lot of energy.

For prices quoted for material from the Battery catalog. net. ua, blocks for HP 65 W cost 452 UAH, USB-C – 497 UAH, batteries – 768 UAH.

Before purchasing, check the exact model of the laptop. Since the autonomy has noticeably shortened due to this very need, reverse the wear of the battery: its replacement may be worth the cost of an additional power bank.
