| Pros | Cons |
|---|---|
| Fast Qi2 charging | Low real-world capacity |
| Efficient Qi2 output | Poor recharge efficiency |
| Metal kickstand | Weak magnetic strength |
| Runs cool |
Of all the 5,000mAh Qi2-certified battery banks we tested, the Mophie Snap+ Powerstation Mini stood out for a surprising reason: it’s fast. Not in wired performance but in Qi2 charging, this tiny pack pushed out a top-tier 26% iPhone charge in 30 minutes while keeping its cool. That’s rare.

How Do We Test
We don’t just look at specs and call it a day. Every power bank we review goes through a series of real-world and lab-based tests to figure out how it actually performs. Below are the specific tests we run on every Qi2 battery pack before giving it a ranking.
- Real Capacity Testing: We fully discharge each battery pack using calibrated power meters to measure the actual energy (in Wh) delivered to a device. This helps us determine whether the stated capacity is accurate and if not, by how much. It’s the best way to tell if you’re getting what you paid for.
- Wired Charging Performance: We test wired output across all supported PDO (Power Delivery Object) and PPS (Programmable Power Supply) profiles. Using meters and voltage analyzers, we record output stability, voltage drop, and protocol accuracy. Each protocol is scored based on its ability to maintain power under real-world loads.
- Qi2 Wireless Charging: We test wireless charging by attaching the pack to an iPhone and measuring how much charge it delivers in 30 minutes. We log both the percentage gained and the actual watt-hours transferred. This gives us a real-world speed benchmark for wireless use.
- Efficiency Testing: We compare the energy drawn from the battery pack to what’s actually delivered to the device (both wired and wireless). Efficiency matters: high losses mean wasted energy and more heat. Each pack gets a score for wired efficiency, Qi2 efficiency, and Qi2 thermal efficiency.
- Thermal Monitoring: We track temperatures during wired discharge, recharge, and Qi2 charging using sensors placed on the battery surface. This helps us identify thermal choke points or heat buildup that could limit performance or comfort in use. Products that stay cool under pressure earn extra points.
- Recharge Performance: We measure recharge speed (Wh per minute) and recharge efficiency (how much energy is needed to fully refill the pack). Fast recharging is great but not if it takes double the energy to do it. We test both metrics to determine how well-designed the recharge circuitry is.
- Magnetic Strength: Using calibrated force gauges, we measure the magnetic push and pull strength of each pack. This simulates real-world use: will the pack stay attached in your pocket or fall off if bumped? We also factor in how usable the pack feels when attached during charging.
- Size, Weight & Energy Density: We weigh each battery and measure its dimensions to calculate Wh per gram and Wh per cm³. A pack might perform well, but if it’s bulky and inefficient with space or weight, that knocks it down a few points. Portability still matters especially for wireless-first products.

| Ports | 1 × USB-C |
| Magnetic Strength (avg 18.9 N) | 14.8 N ❌ |
The Snap+ keeps things simple: a single USB-C port, LED dots for battery level, and a sturdy metal kickstand that’s honestly one of the best we’ve tested. The rest of the body is plastic, but the build feels tight enough for everyday use. It’s light, compact, and clearly made with iPhone users in mind.
Performance

|---|---|
| Wireless Energy Delivered to iPhone in 30 mins (avg 2.9 Wh) | 3.59 Wh ✅ |
| Wireless Energy Drawn from Battery Bank in 30 mins | 4.50 Wh |
| Max Temperature (avg 53 °C / 127 °F) | 46.1 °C ✅ |
| Efficiency (avg 64%) | 80% ✅ |
In our PDO and PPS testing, the Mophie scored well for voltage accuracy and stability. But its real-world wired performance was just okay. It discharged 11Wh on average (from a claimed 19.3Wh), and recharged in just over 2 hours by taking in 21.9Wh. That’s a recharge efficiency of 50%, which is below average.

| Energy Required for 100% Charge | 21.9 Wh |
| Recharge Time | 134 min (~2h 14m) |
| Real World Efficiency (avg 61%) | 57% ❌ |
The star moment was its Qi2 wireless performance. We consistently got 26% (3.6Wh) in 30 minutes, with the pack only needing 4.5Wh to deliver it. That’s an 80% wireless efficiency.
Thermals
Despite its strong Qi2 output, the Snap+ stayed impressively cool. Our tests showed 38.4°C during discharge and 46.1°C during a 30-minute Qi2 sprint. Most other packs ran at least 5–10°C hotter at similar output levels.

| Standout Feature | Large sturdy kickstand + runs cool |
At $70, the Snap+ is pricey for a 5k battery. It also offers a low energy density of 0.06 Wh/g and just average magnet strength. But the performance-to-size ratio is surprisingly solid. If wireless charging speed and a reliable kickstand matter more to you than raw watt-hours, the value starts to make more sense.
Verdict
The Mophie Snap+ Powerstation Mini won us over with speed and thermals, not endurance. It won’t keep your phone alive through a weekend, but if you’re after fast Qi2 top-ups and a satisfying kickstand experience in a compact shell, it punches above its size. Just be aware of the limited total energy and high cost-per-Wh if you plan to use it heavily.
