Hp Laptop Cannot Charge Battery

Internal battery lasts only 4 hours. Cannot charge while using it. Those are the only flaws. Digital means a cleaner signal, metal housing, 900mhz is superior to the 2.4ghz ones, the transmitter is rack mountable, pricing much better than sennheiae

I have never had an issue with genuine HP cartridges. Cannot say the same for off-brand cartridges.

Original Fujifilm battery. Cannot get anything better

Plugged into HP power supply with a 7.4mm plug and was able to charge a HP laptop with with a 4.5mm charge port.

Cannot be better!

I bought this item as a replacement for the battery on my HP laptop. After reviewing my options, this item was well rated, and I have always had excellent experiences with items I've purchased though B&H. The battery was easy to attach to the laptop and the instructions for charging it were clear. So far the battery has worked very well.

HP laptop is great

Put my new HP laptop in it and other items etc.

I use it with cameras, phones, iPads, and even my laptop. Holds its charge very well. Great battery. Perfect size.

I don't use any V-Mount gear so I can't speak to that, but the plethora of ports on this thing and the wide range of USB power implementation is fantastic. The screen tells you exactly what is going on with each port when in use, and what voltage devices are requesting/receiving. It handles just about every USB power standard I know of, and claims to have quite a few safety protections for peace of mind. I use this to power my entire location recording rig: Zoom F8n Pro, a standalone stereo mic pre, even a laptop, screen, or camera if I need to. I charge the battery itself over USB C with a standard 65W laptop charger, which takes remarkably little time. Actually living the consumer DC power unification originally promised by USB C years ago is pretty wild. Clients often forget to charge their iPad/laptop/tablet/phone before sessions, often using those devices to read sheet music, and having this battery available has saved multiple recording dates and made some very happy clients. I also bought the 50Wh version which is great for travelling as light as possible for shorter gigs. Same general features and ports.
