The orb of charging was a tool that appeared in NetHack Plus and SLASH 6, and also appears in NetHack brass. It appears as a glass orb when unidentified.
In SLASH'EM, the orb is a deferred feature - its code can still be found in the SLASH'EM source, but has been commented out with the note of "potential for abuse".[1][2]

Effects
Applying a charged orb of charging allows you to select and recharge an item, similar to a scroll of charging, and auto-identifies the orb. The effect is dependent on the beatitude of the orb.
Nothing will happen when applying an orb of charging with no charges.

Strategy
All non-crystal ball glass orbs have a base price of 750 zm and weigh 75 aum, making it somewhat easier to tell an actual crystal ball apart from the other magical orbs (outside of NetHack brass, where the crystal ball also weighs 75 aum). Beyond this, the three non-crystal ball orbs can be distinguished by identification or use-testing - the latter is risky due to the change of a glass orb being an orb of destruction.

The orb had no charges.
