Revainrating 5 out of 5

Works great with my Meade telescope

As the title says. Great compact power supply, beats trying to run a cable out to the yard to power my scope! That's my review.

Pros
  • Easy to install and use
Cons
  • Might not hold a full charge if left uncharged for an extended period

Work great but it's an 11.1v battery not a 12v

I like that it stays charged for months without losing charge. I dislike that I bought a 12v 3ah battery and got an 11v 3ah battery. In other words if you are powering a 12v device is will not be as powerful as its supposed to be

Pros
  • Can be used as a power bank to charge other devices, such as smartphones or tablets
Cons
  • The battery pack might not be suitable for some types of LED strips or camera models

Good capacity: my feedback

I use it for a Morse code keyer in code class. Nice that it's rechargeable. Comes with a Y connector that will let you charge the unit and/or power something else with the one cable. I bought a separate jumper cable but didn't actually need it.

Pros
  • Rechargeable DC12V and 5V USB Double Output Lithium ion battery pack. Small size, 3000mAh high capacity, easy to carry. Voltage range of the 12V output port is 12.6-9V, it is not constant, compatible with most 12 volt devices.
Cons
  • Might malfunction if dropped or exposed to excess pressure
