Powerextra DF-400
Score: 59/100
Meike MK-320S
Score: 74/100Rankings
The Meike MK-320S is an ultra-compact Sony-compatible TTL speedlite delivering a strong 32 m guide number, HSS, optical wireless and a built-in LED modeling light. Battery-driven operation leads to slower recycle and limited runtime, and the fixed beam angle restricts coverage. Perfect for travel and portrait photographers needing a pocket-size flash with full TTL functionality.
The Powerextra DF-400 is a budget manual speedlite offering a GN33 output, full head swivel and a 18-180 mm zoom range. Its trade-offs include the absence of TTL, high-speed sync and a relatively slow full-power recycle. It is best for beginners and hobbyists needing an affordable, versatile flash for indoor and off-camera use.

Professional reviewers consider the Powerextra DF-400 a solid entry-level flash that offers good value for its price, thanks to its GN 33, full head swivel, and wireless slave capabilities. However, they note significant drawbacks such as the lack of TTL/HSS, a relatively slow full-power recycle, and a plastic build that feels less robust than competing models.
Everyday users praise the flash for its low price, long battery life, and ease of use across many camera brands, while repeatedly criticizing the cheap plastic construction, slow full-power recycle, and inconsistent performance at very high shutter speeds.
Professional reviewers commend the MK320S for packing a robust feature set-TTL, HSS, stroboscopic up to 500 Hz, and optical wireless-into an ultra-compact, metal-body flash, noting its intuitive LCD and USB-Micro charging as strong value points, while flagging its fixed beam angle and lack of radio wireless as notable trade-offs.
Everyday users consistently praise the flash's portability, surprising power output, even lighting and ease of use for beginners, especially the TTL auto mode and LED assist, but they commonly complain about the rapid drain of AA batteries, slower recycle speed, limited head rotation, and occasional overheating in high-frequency strobe use.
“Cheap entry ($26) and great battery life up to 1500 flashes”
