Great unit! Doubling run time. Easy connection with umbilical. Shows up on anker Bluetooth app once downloaded and connected. CX1000 charges first and then charging starts on the BP1000 with it showing charging level display on the app. App also allows for high speed charge for both units when selected.

The only way to make it better is to make it rechargeable separately and it should have the same kind of handle as the base model.

Perfect addition to my solar generator. I use it while working on my property that is off grid.

Great addition with reliable service. It will extend my offered camping 2 fold. Glad I bought it.

As a HAM, I purchased this product as a safer alternative to having lead-acid batteries in my home as backup power for my radio equipment. I already have a 10KW gasoline generator to provide whole-house power. The ANKER unit will be a "bridge device" to have power for equipment and small appliances without having to constantly run the generator if another major power emergency happened. I can use the generator or solar panels to charge the ANKER unit and let it power things that need constant, but small to medium power demands.
