Works great
Works fine.
This cable is great for powering devices from a battery pack with USB A jack output. Seems to be well made.

Needs frequent recharging
The original battery in the T5 was rated at 1400 mAh. These replacements are 900, and the difference is striking. Playing a video, or even reading an e-book runs down the battery quickly. They will need a daily recharge.

Work fine if you know what you're doing
Opening the BNTV400 and replacing the battery is pretty straightforward.
The battery connector is not a tight fit, so make sure it's on right.
Now, here's the important part. The initial battery charge must be from a charger that can handle 2 amps. That means many el cheapo chargers won't charge it. It pulls well over 1 amp on the initial charge. For subsequent charges a lower-current charger may work.
