Note: The following is part of our roundup of B-C battery packs. Go there for details on how we tested this device.

The RAVwer 26,800 mAh (99.16) ($80 on Amazon) battery pack is sleek unassuming. Four indicator lights just above the power button blink flash blue as the device is charging or discharging.

Four different ports adorn the front of the pack, with a microB port for charging, a B-C port for charging or powering your phone, along with two B-A ports with RAVwer’s “iSmart” technology.

Using its smarts, the RAVwer pack is supposed to detect adjust current up to 2.4A, with a max of 3.5A output across all ports.

Total charge time through the microB port was nearly 11.5 hours, charging at 5V 1.7A (out of an expected 5V/2A). Charging through B-C using the company’s included wall adapter drastically decreased charging time to four hours.

The biggest downside is the lack of QuickCharge 2.0 3.0 support. RAVwer does offer another mode with QC 3.0 B-C support; In exchange for faster charging, you lose a bit of capacity dropping the pack down to 20,100 mAh.

In testing, the battery stopped depleting at 81.33, giving it an efficiency rating of 82%. Unfortunately, 82 percent puts it on the bottom half of the packs tested, just below the Anker werCore+ 85 percent efficiency, despite nearly identical capacity capabilities.

Inside the box you will find a 30Type-C Charger (something employee son ung suggests you do not use with your phones, though it should be fine to charge this battery pack), a carrying case, 2 microB cables.
