Is a compatible charger safe to use instead of the original?
A compatible charger can be as safe as an original one, provided it matches the connector and voltage exactly, supplies at least the original wattage, and carries proper protection circuitry. Safety comes from those specifics, not from the original-versus-compatible label alone.
In short: Check the connector, voltage, wattage and protection circuitry on the label. A frayed cable, a cracked casing, or a charger that gets hot enough to smell of burning is a fire risk regardless of brand, and should be stopped immediately. Match your laptop’s own rating label against the charger’s before you rely on it.

What is the difference between an original and a compatible charger?
An original charger is sold under the laptop brand’s own name for that specific model. A compatible charger is built to the same connector, voltage and wattage specification but sold separately from the laptop. Neither label by itself tells you whether a specific unit is safe: that depends on whether it matches your laptop’s requirements and carries adequate protection circuitry.
Aureval Computers & IT Solutions, Nehru Place, New Delhi, lists each charger it supplies by its published brand name, wattage, voltage and connector on that charger’s own product page — see the laptop chargers & adapters page for the full list.
What protection circuitry should a laptop charger have?
Basic protections to look for are over-voltage, over-current, over-temperature and short-circuit protection. These stop the charger from delivering unsafe power if something goes wrong internally or at the laptop end.
Where a protection is stated on a product page, it will be listed there: for example, the ASUS ROG 240W Laptop Adapter is listed with over-voltage, over-current, over-temperature and short-circuit protection, and the HP 65W USB-C Laptop Adapter is listed with short-circuit protection and a charging indicator. Where a page does not list a protection, that information is not published, not necessarily absent.
Does a compatible charger negotiate wattage the same way as the original?
A USB-C charger and laptop negotiate power together, so the laptop draws only what it needs up to the charger’s maximum; a charger with too little maximum wattage will charge slowly or not at all, regardless of whether it is original or compatible.
This negotiation behaviour is sometimes described on the product page: for example, the HP 65W USB-C Laptop Charger is listed as smart power that adapts between 15W, 27W, 60W and 65W to suit the device. A barrel-pin or MagSafe charger does not negotiate in this way and instead needs an exact voltage match.
What does a manufacturer warranty actually cover on a laptop charger?
A manufacturer warranty covers defects in that specific charger, on the terms the manufacturer sets, for the period stated. Aureval Computers & IT Solutions, Nehru Place, New Delhi, states this plainly: “Sealed units, supplied on GST invoice with manufacturer warranty.” Read the full terms on the return & replacement policy page before you order.
How do I check BIS registration on a laptop charger?
Laptop chargers sold in India fall under BIS (Bureau of Indian Standards) compliance requirements. A registered charger carries a registration or CRS (Compulsory Registration Scheme) number printed on its rating label, alongside its wattage, voltage and safety marks.
Check the rating label of any charger you are considering for this number, the same way you would check its wattage or connector. This is a check to make on the physical label yourself; it is a buyer-side check and not a claim this page makes about any specific product.
What does Aureval supply?
Aureval Computers & IT Solutions, Nehru Place, New Delhi, supplies the chargers listed on this site, brand by brand, at the wattage, voltage and connector published on each product page. Sealed units, supplied on GST invoice with manufacturer warranty. No claim is made here, or on any product page, of original-equipment, authorised-distributor or genuine-sourcing status beyond what each product page states.
For the exact specification and listed models of a specific charger, see its brand page or product page directly, for example HP, Dell, Lenovo, ASUS, Acer, Apple or the full laptop chargers & adapters range.
What do buyers ask about compatible chargers?
Will a compatible laptop charger damage my laptop?
A charger can damage a laptop if its connector or voltage does not match, or if it lacks basic protection circuitry. Matching the connector and voltage exactly, and choosing a wattage equal to or higher than the original, is what determines safety, not simply whether the charger is original or compatible.
Does using a compatible charger void my laptop’s warranty?
This depends on the laptop manufacturer’s own warranty terms, which Aureval does not set. Check the warranty documentation for your specific laptop, or ask the manufacturer directly, before relying on a compatible charger under warranty.
How do I know if a charger has adequate protection circuitry?
Check the product page or the rating label for stated protections, such as over-voltage, over-current, over-temperature and short-circuit protection. For example, the ASUS ROG 240W Laptop Adapter’s product page lists all four of these protections.
What should I check on a charger’s rating label before buying?
Check the wattage, voltage and current, the connector type and size, and the compliance markings printed on the label, including a BIS registration or CRS number where applicable. Match these against your laptop’s own rating label or specification sheet.
Where can I check a specific charger’s specification?
See the HP, Dell, Lenovo, ASUS, Acer and Apple charger compatibility tables for a model-by-model match, browse every charger on the laptop chargers & adapters page, or read the laptop chargers and power adapters guide and the complete guide to chargers, docking stations and hubs for how to match connector, voltage and wattage.
