The Anker Zolo B121E is a two-pack of compact 50W wall chargers, each with two USB-C and two USB-A ports, suited to people who want to charge several phones, earbuds, watches, or other USB devices from one outlet.
Recommended For
- Frequent travelers or commuters who want one compact wall charger for a phone, earbuds, and other small devices, with foldable plugs and four ports to reduce the number of adapters they pack.
- People setting up a shared bedside or desk charging spot for phones, tablets, earbuds, or watches who want to charge several small devices from one wall outlet.
- Households or users with a mix of newer USB-C devices and older USB-A cables who want one charger that can accommodate both types.
- People who want to keep a phone charging quickly while also topping up a second USB-C device; the two USB-C ports support up to 30W and 20W, respectively, when used together.
Real-World Use Scenarios
- On a trip with one accessible outlet, charge a phone and a second device—such as a tablet or earbuds—at the same time; the primary USB-C port can keep its higher output while another port is in use.
- At a bedside or shared desk, plug in several phones and small accessories instead of occupying multiple outlets; expect charging to be slower when all four ports are used.
- For a short trip without a laptop, use it as one compact charger for everyday devices; a community user describes it as their go-to for outings and short trips.
- In a household with both newer USB-C devices and older USB-A accessories, use the mixed ports to charge them from the same wall adapter rather than bringing separate chargers.
- Keep one of the two included chargers at home and pack the other for travel, so a multi-device charger is available in both places.
