• Consistently noted by users: It cannot fold in, which may be inconvenient when packing in bags or tight spaces 

• Design limitation: Contra some feedback, it lacks a blue LED—great for bedrooms but not ideal for visibility .

2. Gets hot under heavy load

• Heat buildup at full output: Users report it “gets hot to the touch” when operating near 18–20 W  Although still within safe bounds, the heat may concern some users 

3. Single-port, limited wattage (20 W)

• Not suitable for multitasking: No ability to charge multiple devices simultaneously—only one USB‑C port available 

• Insufficient for demanding devices: Delivers only 20 W—not enough for laptops, tablets, or newer smartphones that support 30 W+ charging 

4. Lacks USB‑PD PPS support

• Suboptimal for some Android devices: Devices like Samsung Galaxy S21 series charge more slowly (~14 W instead of up to 25 W) because the adapter doesn’t support PPS 

5. Premium pricing for its class

• Perceived costlier than peers: At around $20, some say it’s “relatively expensive” for a minimalistic 20 W charger .
