The Aifen 3310 Pro power supply is a 330W adjustable switching DC unit built for mobile phone repair benches. It gives you 0–33V and 0–10A output with CV/CC switching, so you control voltage and current independently during dead phone diagnosis, battery activation, and CPU/IC-level repair. Four M1–M4 memory keys store your go-to settings, while dedicated 6.2V and 8.4V quick-shift buttons speed up battery testing. Pulse protection, continuous protection, and low-ripple output keep sensitive board components safe during short circuit testing. Front and rear DC terminals plus five USB ports round out a unit that fits any GSM repair workshop.

Description

Aifen 3310 Pro 33V/10A 330W Adjustable DC Power Supply

Every repair bench needs a power supply that tells you the truth about a board before you touch it with a soldering iron, and the Aifen 3310 Pro power supply handles that job with a 0–33V, 0–10A adjustable output and 330W of maximum power. That’s enough headroom to run current-draw tests on a dead phone, activate a discharged battery, or hold steady voltage during CPU and IC reflow work.

You set the exact voltage and current your board needs instead of guessing with a fixed adapter. The switching-mode design keeps ripple low, so sensitive components on a motherboard don’t see the electrical noise that a cheap linear supply lets through. When you’re chasing a short or a dead-after-flash fault, that stability matters — you need a clean, accurate current reading, not a jumpy one that sends you down the wrong repair path.

Constant voltage and constant current (CV/CC) modes switch automatically depending on what the board draws. Set your voltage limit, and the unit holds current steady once the board pulls past your threshold — this is exactly how you isolate a short circuit without frying the trace you’re testing. Pair that with pulse protection and continuous protection modes, and this adjustable DC power supply for mobile repair cuts output the moment it detects an abnormal spike or a dead short, protecting both the board and your test leads.

Battery work gets its own shortcut. The dedicated 6.2V and 8.4V quick-shift buttons are built for lithium battery activation — you press once instead of dialing in the exact voltage every time you need to wake up a battery that’s dropped below its safe threshold or verify a two-cell pack’s charge voltage. If battery activation is a daily task in your workshop, this cuts real time off every job.

Four M1–M4 memory keys let you save your most-used voltage and current combinations. If you’re running the same test parameters on iPhone logic boards every day, or switching between a MediaTek and Qualcomm workflow, you recall the exact setting with one press instead of resetting the dial each time. Combined with the real-time digital display showing live voltage and current down to 0.01V/0.01A, you always know exactly what’s hitting the board.

Bench Connectivity and Output Ports
Connectivity covers both the bench and the charging side of your work. Front and rear DC output terminals mean you’re not stuck reaching around the back of the unit mid-repair, while four adjustable 0–33V USB ports plus one fixed 5V/2A USB port let you power or charge phones directly from the same unit — useful when you’re testing a charging issue and need a controlled auxiliary output rather than tying up a second adapter.

In terms of where the 3310 Pro fits your workflow: a 33V 10A power supply like this sits at the diagnostics stage, before you commit to board-level repair. You use it to confirm whether a phone has a genuine short, check current draw patterns that point to a specific faulty component, or verify a battery is dead versus a charging IC fault. From there, your workflow moves into board-level work — this is where a good soldering station, hot air rework station, and microscope come in for component-level repair, and where an ISP box or UFS/eMMC programmer takes over once you’ve ruled out hardware faults and need to check software or storage-level issues. The 3310 Pro doesn’t replace those tools — it’s the diagnostic step that tells you which one you need next.

Housed in a compact 115 x 215 x 180 mm chassis with side ventilation for heat dissipation during long sessions, the unit runs on standard AC input (100V/60Hz or 220V/50Hz), so it works on Pakistani mains power without a separate converter. It ships with the main power supply, an AC power cord, alligator clip test cables, and a user manual — everything you need to start testing boards out of the box.

Whether you’re running a one-person repair counter or a full-service GSM center handling iPhones, Samsung, Xiaomi, Oppo, Vivo, and other Android boards side by side, having the Aifen 3310 Pro power supply on your bench cuts down guesswork on dead phone diagnosis, board-level current testing, and battery activation — the three checks nearly every repair job starts with.
