Four connectors on one keychain reader looks like a spec-sheet boast until you're at a gate with a phone at twelve percent and a card full of buck photos. The SUNTRSI 4-in-1 answers that with a charging port of its own: run your Lightning cable into the reader while a card is mounted and the phone keeps topping up as you scroll. That one socket is why it's our top pick over the cheaper two-connector readers here. Checking three cameras in a morning eats a phone battery, and this is the only reader on the page that gives it back.
Both slots are on board, full-size SD and microSD, which covers the card in a game camera and the smaller one in a handheld or a dash cam. Nothing needs installing: the card mounts in the iPhone Files app or an Android file browser, and from there you can copy stills, play video clips, and clear space in a few taps. It transfers in both directions too, so a card carries files out to the field as easily as it brings photos back.
The details are what kept it in our kit. Each plug has its own cap, which matters once a reader has spent a season in a console full of grit, and the keychain loop means it rides with the truck keys instead of living loose in a glove box. At 2.72 inches long it's bigger than a bare dongle; that length is three extra connectors you never have to remember.
