Portable Power for Everyday - 4V USB Lithium 3.0Ah Battery & Power Bank

Not only does the 3.0Ah USB Lithium Battery power every tool in the RYOBI 4V Range, but it can also be used as a separate power bank! Never get caught out with a flat phone battery again, simply connect the 3.0 Ah USB lithium battery to your phone to keep charged up for life’s critical moments.
This innovative battery is equipped with a convenient fuel gauge LED indicator, which provides at-a-glance information about its current battery level. When it's green, you've got a full battery ready to power your tools and tackle your tasks. When it's yellow, you're at the halfway mark, and when it turns red, it's time for a recharge. With this clear visual cue, you'll always know where you stand with your power supply and charge your phone completely with one fully charged battery.
