Recently, I realised that 1 x 12V output of the YE!! power pack was not going to be sufficient. I needed 2 x 12 V outputs in order to be able to power the iOptron ZEQ25 mount and my Lacerta MGEN autoguider. Hence searching on Amazon, I found the Sunsbell power pack. It also comes with a very useful accessory, which will make it very useful for astronomy. It holds 16,800mAh and costs less than the Ye!! power pack @ £58.99 from Amazon.
Notice that it has a 12V car battery socket adapter. Pair this with a car socket multiplier (sold separately), and you could power many different pieces of equipment with it. And the 12-15V output will work with equipment that draw up to 15A – now that’s alot.
The car starting capabilities of this battery pack is much more than the Ye!! power pack, being able to generate 800A vs the 400A of the Ye!!. Hence even high capacity diesel engines would not pose a problem for this car starter.
I have to say that out of the bag, it was nearly fully charged as within a few seconds of attaching it to the mains via its charger, the 4 LEDs of the battery status were fully lit; makes me think that it will hold its charge fairly well with very slow battery drain over time.
What do I like about the Sunsbell power pack?
- Very good price @ £58.99.
- It comes with 2 x 12V outputs. Couple this with the car battery socket, it potentially could power many more different devices when coupled with a car socket mulitplier.
- It holds even more charge than the Ye!! power pack @ 16,800mAh. That’s going to last a very long time, even with dew heaters draining its power.
- The fact that it was nearly at full power straight out of the box, suggests that it likely has slow battery drain – which is great.
What could be improved?
I can’t think of any at this price point and the great features it has.
Highly recommended. If you need a power pack to work all your equipment out in the field for astronomy, this little pack will likely work well for you – especially when pair this with a car socket multiplier.
