FAQ

What types of products does Lapwise sell?

Lapwise sells laptop accessories for protection, portability, charging, connectivity, workspace organization, cooling, privacy, and everyday productivity. Our selection includes laptop sleeves, bags, stands, chargers, hubs, docking stations, portable monitors, screen protectors, cleaning tools, and security accessories. We do not sell laptop computers.

How can I check whether an accessory is compatible with my laptop?

Please review the product description, supported models, dimensions, connector type, voltage, wattage, operating-system requirements, and other compatibility information before ordering. A matching screen size or connector shape does not always guarantee compatibility.

How much does shipping cost?

Lapwise charges a flat shipping fee of $6.90 per order unless a different amount is clearly displayed during checkout. Customers will not be charged an additional shipping fee solely because an order is shipped in multiple packages.

How long does order processing take?

Orders are generally processed within 1–3 business days, excluding weekends and public holidays. Processing may take up to 5 business days during promotional periods, high order volume, payment verification, or product availability checks.

How long will delivery take?

Estimated delivery within the United States is generally 5–10 business days after shipment. International delivery, where available, is generally estimated at 10–20 business days after shipment. Carrier, weather, customs, and address-related delays may affect delivery times.

How can I track my order?

Once tracking information becomes available, we will send a shipping confirmation email containing the tracking number or tracking link. Tracking updates may take several business days to appear after a shipping label is created.

Can I change or cancel my order?

Please contact us as soon as possible at gobralwbhopalne@gmail.com. Changes and cancellations are not guaranteed because orders may enter processing shortly after being placed. Once fulfillment or shipment has started, you may need to request a return after delivery.

What is your return policy?

Eligible products may generally be returned within 30 days of delivery. Items should be unused, uninstalled, and returned with the original packaging, accessories, and included components. Contact us before sending any return so that we can provide the correct instructions and authorized return address.

What should I do if my order arrives damaged, defective, incomplete, or incorrect?

Contact us promptly at gobralwbhopalne@gmail.com with your order number, a description of the issue, and clear photos of the product, packaging, shipping label, and included components. Please keep all packaging materials until the issue has been reviewed.

How can I contact Lapwise customer support?

Email us at gobralwbhopalne@gmail.com for assistance with orders, products, compatibility, shipping, returns, or store policies. We aim to respond to most inquiries within 1–2 business days, although responses may take longer during weekends, holidays, or high-volume periods.
