Are 9v1 and 9v2 the same?

No, unfortunately there are very small differences in size of 9 volt batteries, even in brand name 9v batteries such as Energizer (or Energizer Industrial) and Duracell (or Duracell Procell). This plays a significant role in 9v batteries fitting properly into a device.

Do Digital photo frames have memory?

Does the Digital Picture Frame have built-in memory? No. The Digital Picture Frame does not have any internal memory to store your files. You must use a compatible memory card to play your Media files.

How does the Digital photo frame work?

The most basic digital picture frames contain a certain amount of internal memory and a USB port. You simply connect the frame to a computer via USB and the frame shows up looking like a flash drive, and then drag and drop images to the frame until the memory is full.

Which brand of 9V battery lasts the longest?

Ultralife Lithium 9Volt battery
The Ultralife Lithium 9Volt battery was launched in 1991 as the world’s longest lasting lithium 9V battery.

Can a 1.5A power adapter be replaced with a 1A supply?

Since that may be in the 1-1.5 Amp range, the 1A supply is not good enough. The 1A supply probably won’t cause any damage. If the device tries to draw more current than it can provide, the voltage will collapse or it will deliberately shut down. Shutting down clearly can’t hurt the device.

Is it safe to use a 9V DC adapter?

Or perhaps to 9V DC 2A? No, it’s not safe to assume that either of those will work. In fact, even if you did find a “8V 2.6A” power adapter it might still not be safe unless you also know whether the old power adapter was regulated or not.

Can a 8V 2.6A power adapter be used?

No, it’s not safe to assume that either of those will work. In fact, even if you did find a “8V 2.6A” power adapter it might still not be safe unless you also know whether the old power adapter was regulated or not.

What should the voltage be for a new DC adapter?

If the old supply put out 8 V and 2.6 A and the equipment says it wants 8 V, then the obvious answer is a power supply that puts out 8 V and 2.6 or more amps. The equipment might be OK with 9 V, or not.
