Questions and answers

Will this charge my Lenovo laptop?
BTI lists it as Lenovo-compatible with USB-C Power Delivery at 45W. Check your laptop's required wattage first; 45W suits ultraportables, not high-power models.
Is 45W enough for my laptop?
It is enough for most thin-and-light laptops that ship with a 45W USB-C charger. Gaming or workstation laptops that need 65W or more will charge slowly or not keep up under load.
Can I use it abroad?
Yes. The input range is 100–240V AC, so it works in most countries with the right plug adapter. You still need a travel adapter for local outlets.
Does it come with a USB-C cable?
The listing describes a wall charger with a USB-C cable type but does not confirm a bundled cable. Plan to supply your own USB-C cable if one is not included.
Is it cheaper than a Lenovo original charger?
At $12.88 at eBay as of November 4, 2026, it costs far less than most Lenovo-branded 45W USB-C adapters. The trade-off is third-party build and warranty support.
When is the best time to buy?
Third-party chargers like this see small discounts around back-to-school and holiday sales. At under $13, the price is already low, so waiting rarely saves much.
Where is the BTI 45WUSB-C-BTI-LN 45W Type-C AC Adapter cheapest?
At eBay, for $12.88, 57% under what the other stores charge, as of our latest check.
Where can I buy the BTI 45WUSB-C-BTI-LN 45W Type-C AC Adapter?
