Review on 🔌 ACK-E2 USB Cable + DR-400 BG-E2 E2N BP-511 Dummy Battery + USB Adapter Kit for Canon EOS 20D 30D 40D 5D 50D D30 D60 by Malik Munns

I bought this as a time lapse and astrophotography solution for my Canon 40D. Considering the price, this product offers great value for money compared to other options on the market as you can use the power adapter for wired shooting or the USB adapter with portable power bank, but it doesn't work with all USB rechargeable batteries . .While the description says an input current of 2-4A is acceptable, I've found that it doesn't work with USB battery packs rated at 2.1A, which is pretty normal. 2.4A is the minimum requirement to turn on the camera, so I had to buy an extra battery, to meet this specification. I've also found that some batteries that aren't rated for low-drain devices can shut down after prolonged exposure to an incandescent light when current draw is minimal, and this frustrated me. In the end I was very happy when I found a battery that meets all these requirements (Anker PowerCore Lite 20000 mAh) that has 2.4A connectors and an additional "always on" dummy charging mode that, although For current devices such as headphones, the battery was not automatically disconnected during lamp exposure. and that upset me. In the end I was very happy when I found a battery that meets all these requirements (Anker PowerCore Lite 20000 mAh) that has over 2, 4A connections and an additional "always on" dummy charging mode, which, although it is used for current devices such as headphones, the battery was not automatically disconnected during lamp exposure. and that upset me.
