Lenovo B40 Charger

Description

Lenovo B40 Charger — Reliable 65W Power Adapter for UAE Business Users

The Lenovo B40 Charger is in stock now at BatterySouq.ae — a reliable 65W power adapter built to Lenovo’s exact output specification of 20V / 3.25A with a round barrel connector, manufactured with Grade-A verified components, and backed by a full UAE warranty.

The Lenovo B40 series is Lenovo’s 14-inch compact business laptop family — the portable counterpart to the 17.3-inch B70 in Lenovo’s B-series business lineup.

The B40 family spans four primary variants — the B40-30 featuring Intel Celeron and Pentium Bay Trail configurations, the B40-45 featuring AMD A-series APU options, the B40-70 featuring Intel Core i3 and i5 Haswell configurations, and the B40-80 featuring Intel Core i3 and i5 Broadwell and Skylake options.

All four B40 variants use the same 20V / 3.25A round barrel connector — Lenovo’s consistent charging standard across the B-series and G-series budget business and consumer laptop families.

The B40’s 14-inch compact form factor draws less panel power than the 17.3-inch B70 — but the 65W output of this adapter correctly covers the combined processor, integrated graphics, and display demands of all B40 variants during sustained business workloads.

Lenovo’s proprietary charging circuit communication applies across all B40 variants — an adapter without the correct identification signal triggers the “Power supply not recognised” BIOS warning across B40-30, B40-45, B40-70, and B40-80 alike.

This Lenovo B40 Charger delivers stable 20V / 3.25A with correct Lenovo charging circuit communication — covering all four B40 variants from first connection without warnings or throttling.

Order today from BatterySouq.ae — in stock, same-day dispatch available, and delivered anywhere in the UAE within 1–3 business days.

Key Features

Exact 65W Output — Verified for All Lenovo B40 Variants The Lenovo B40 Charger delivers exactly 20V at 3.25A — the complete 65W output required by the B40-30, B40-45, B40-70, and B40-80 for full-speed charging across Intel Celeron, Pentium, Core i3, Core i5, and AMD A-series configurations without battery drain.

Round Barrel Connector — Correct B40 Series Connector Uses Lenovo’s round barrel connector — the B-series and G-series standard physically distinct from the slim rectangular tip of Lenovo’s E-series and newer IdeaPad models. Correctly matched to all B40 variant charging ports and verified before dispatch.

All Four B40 Variants — One Verified Adapter The Lenovo B40 Charger covers the complete B40 family — B40-30 Intel Bay Trail, B40-45 AMD A-series, B40-70 Intel Haswell, and B40-80 Intel Broadwell and Skylake. One correctly authenticated 20V / 3.25A adapter for the entire B40 range.

Lenovo B40 Charging Circuit Recognition Correctly identified by all B40 variant BIOS systems — preventing the “Power supply not recognised” warning and ensuring Celeron, Pentium, Core i3, Core i5, and AMD A-series B40 processors operate at full performance without power restriction from adapter non-recognition.

Intel Bay Trail Platform — B40-30 Calibrated for the B40-30’s Intel Celeron N2840 and Pentium N3540 Bay Trail processor platform — energy-efficient quad-core configurations delivering stable 20V output for everyday business document and web workloads.

AMD A-Series APU Platform — B40-45 Verified for the B40-45’s AMD A4, A6, and A8 APU configurations — including shared Radeon GPU power draw alongside CPU cores during everyday business productivity tasks.

Intel Haswell and Broadwell Platform — B40-70 and B40-80 Calibrated for the B40-70’s Core i3-4030U and i5-4210U Haswell configurations and the B40-80’s Core i3-5005U, i5-5200U, and i5-6200U Broadwell and Skylake variants — covering Intel HD Graphics 4400, 5500, and 520 integrated platform demands.

Universal AC Input — UAE and International Ready Accepts 100–240V AC at 50/60Hz. Fully compatible with UAE 220–240V power infrastructure and safe for international business travel without any voltage converter required.

Four-Layer Circuit Protection Overvoltage, overcurrent, short-circuit, and thermal overload protection at circuit level — protecting both the adapter and all B40 variant charging ports and batteries during every business session.

Grade-A Verified Components — Tested Before Dispatch Every Lenovo B40 Charger we ship is manufactured with Grade-A internal components tested for voltage accuracy at 20V / 3.25A, connector integrity, thermal stability, and operational longevity before leaving our warehouse.
