Excellent

The extra battery has seamlessly boosted the capacity o LF my Delta 2. It took a while to charge but once it leveled up, synchronised easily and has been working great so far. This is a great power solution for professionals who work from home and need power without having to run a gasoline generator.

A necessary addition

My Delta 2 is now twice its storage capacity. Also, it charges so fast with AC.

Perfect Boost of Delta 2

The Extra Battery is just the best help that you can do to your Delta 2, the capacity of my Delta 2 has actually tripled with this Extra Battery, the initial charging of the Extra Battery was slow but after complete charging and synchronizing with Delta 2, it's just the best...

I like it,

But with no connection cable, how do I link it to the existing unit?

Double Power

This doubled the capacity of my delta 2 There's nothing like having a backup power. Delta 2 saves space, it's very handy and adds to the home aesthetics.
