Battery Buffers are single block machines added by Gregtech, which can both charge and discharge items that hold EU electricity. They are available in one, four, nine and sixteen slot variants for every power tier. Battery Buffers input 2A and output 1A per battery inside. Non-battery items such as armor or tools can be charged in Battery Buffers of their tier.

Buffers are commonly deployed as part of a power protection system for multiblocks to prevent voiding from temporary power grid failures or insufficient production, or to supplement crafts that cannot otherwise be supported by current power infrastructure. Power can be input into any unmarked side of a Battery Buffer, while it only outputs on the front face with a dot. Cables are needed if a buffer will be connecting to multiple machines.
