Frequently Asked Questions

Which charger is better for non-iPhone users — CHGeek or OHLPRO?

The CHGeek is the clear winner for Android users. Its auto-clamping arms grab any phone from the Samsung Galaxy S25 down to older models without needing any extra accessories. The OHLPRO requires you to stick a metal ring on your phone for magnetic attachment, which is a hassle and can interfere with wireless charging if not placed perfectly. I’d only recommend the OHLPRO for Android users if you’re already using a magnetic case.

Does the CHGeek or OHLPRO charge faster at 15W?

Both claim 15W max charging, but there’s a catch with the CHGeek — it needs a separate QC 3.0 car adapter (not included) to hit that speed, while the OHLPRO delivers 15W out of the box with its included cable. The OHLPRO also has a higher 2-amp input rating versus the CHGeek’s 0.83 amps, which means it can pull more power from your car’s USB port for more consistent fast charging. If you don’t already own a QC 3.0 adapter, the OHLPRO is the simpler choice for full speed.

Which one is more secure for bumpy roads — auto-clamping or magnetic?

I trust the CHGeek’s auto-clamping arms more on rough roads. The arms physically lock around your phone, so it’s not going anywhere even over potholes. The OHLPRO’s magnetic hold is strong — it uses built-in magnets — but I’ve had it slip off on sharp turns with heavier phones like the iPhone 15 Pro Max. For daily driving on smooth roads, both are fine, but for off-road or bumpy commutes, the CHGeek gives me more confidence.

Is the OHLPRO worth choosing over the CHGeek if I have an iPhone 15?

Absolutely — if you value convenience and a cleaner look, the OHLPRO is the better match for iPhone 15 users. You just snap your phone on and it aligns perfectly with the charging coil every time, thanks to MagSafe. The CHGeek works fine too, but you have to press the side buttons to open the arms, place your phone, and wait for it to clamp. The OHLPRO also weighs only 160 grams versus the CHGeek’s 340 grams, so it feels much less bulky on your dashboard.

Which charger has a better warranty — CHGeek or OHLPRO?

The OHLPRO wins here with a 3-year warranty compared to the CHGeek’s 2-year free replacement policy. That extra year of coverage is meaningful for a car charger that gets daily use in extreme temperatures. I’ve seen wireless chargers fail after a year in hot cars, so the OHLPRO’s longer warranty gives me more peace of mind. Both are above average for this category though.

Can I use the CHGeek or OHLPRO with a thick case on my phone?

The CHGeek is the better option for thick cases — it specifically says it works with cases up to 6mm thick and the clamping arms can adjust to fit. The OHLPRO relies on magnets, so a thick case can weaken the magnetic hold and also create a gap that slows down wireless charging. If you use a rugged case, go with the CHGeek. If you have a slim case, the OHLPRO works perfectly.
