Approximate prices are provided only as a buying guide and can change.

| Galaxy Tab S10 Lite | About $400 | Mid-tier choice with a larger screen, from the same family as the proven Galaxy Tab S10 FE. |
| Galaxy Tab S11 / S11 Ultra | $675–900+ | Flagship performance. More power than the bench requires, but an excellent premium option. |

Known bad — with the reason
- Galaxy Tab A8 (SM-X200): The tested unit showed a documented failing USB-C port daughterboard, matching the connect/disconnect loop captured in its kernel log. The port is repairable with a replacement daughterboard (approximately $15) and an iFixit repair guide; otherwise, skip this model.
- Amazon Fire tablets: Fire OS is not supported for the RC Discharger Battery Benchmark Android app.
- Older or low-memory tablets: Avoid Android 12 or older and devices with less than 4 GB of RAM.
Before buying an Android tablet: check this list, use the required USB Benchmark Adapter, and connect the mandatory iCharger temperature sensor.
