2 Portable Chargers for iPhone 8 Plus
These picks are ranked by compatibility, capacity, and convenience, counting down to the strongest overall choice.
2. Portable Charger Power Bank for iPhone, 2-Pack
Best for: iPhone users needing backup power
This two-pack includes two compact power banks, one black and one blue. Each unit measures 3.2 by 1.96 by 1 inch and weighs about 100 grams, roughly the size of a lipstick. The built-in plug-in design reduces cable clutter, so one can fit in a pocket, purse, or small travel bag. Each charger has a 5,000mAh battery and should provide about 0.9 to 1.5 iPhone charges, depending on the phone model and battery condition.
The main advantage is convenience for short trips, commutes, or emergency use. The USB-C port supports 15W power delivery and can recharge the bank at up to 3A. It also supports pass-through charging, letting the phone and battery pack charge together. Internal protection covers overcharging, excess voltage, high current, and short circuits. The package includes two USB-C cables, a manual, and a 36-month warranty. Around $29 for two, the set offers useful backup capacity, but it is not designed for extended travel without access to an outlet.
Pros
- Two 100g chargers provide separate backups for home, work, or travel.
- Built-in plug-in design avoids carrying a separate charging cable.
- 15W USB-C input and output support faster recharging than basic mini banks.
Cons
- A 5,000mAh capacity delivers less than two full iPhone charges per unit.
- No wall adapter is included, so you need a USB-C charging adapter or another power source.
1. Miady Mini Portable Charger 2-Pack
Best for: iPhone users on short trips
The Miady 2-Pack includes two small battery packs, one black and one white, for charging older Lightning-equipped iPhones away from an outlet. Each unit has a built-in Lightning connector, so you do not need to pack a separate cable. A USB-C port recharges the power bank. Each pack is rated at 5,000mAh and supports output up to 5V/2.4A.
At 2.95 by 1.77 by 0.98 inches and 0.2 pounds each, these chargers fit easily in a pocket, handbag, car console, or travel pouch. Around $17 for two, they offer a practical backup for commutes, concerts, school, and travel. The connector works best with phone cases thinner than 4mm, and the compact design can attach directly to the phone while charging. Compatibility covers iPhone models from the iPhone 6 through the iPhone 14 lineup, including the SE. The key limitation is clear: these packs do not work with iPhone 15, 16, or 17 models.
Pros
- Two 5,000mAh packs provide separate backups for different bags or users.
- Built-in Lightning connectors remove the need to carry a charging cable.
- Small 2.95-inch length and 0.2-pound weight suit pockets and travel.
Cons
- Not compatible with iPhone 15, iPhone 16, or iPhone 17 models.
- Cases thicker than 4mm may prevent a proper connector fit.
Buying Guide
Usable capacity matters most because an iPhone 8 Plus battery holds about 2,691mAh, while power banks lose energy during conversion. A 10,000mAh model usually provides roughly one to two full recharges.
- Capacity: Choose 10,000mAh for daily backup or 20,000mAh for trips lasting two or more days. Larger models add weight and take longer to recharge.
- Connector and cable: The iPhone 8 Plus uses a Lightning port. Select a pack with a built-in Lightning cable, or include a certified USB-C-to-Lightning cable in your budget.
- Charging speed: For wired fast charging, look for USB-C Power Delivery rated at 18W or higher. Wireless models should support Qi charging at 7.5W, the phone’s practical wireless limit.
- Size and weight: A compact 10,000mAh battery often weighs under 8 ounces and fits a small bag. A 20,000mAh unit commonly weighs 10 to 14 ounces.
- Safety and travel rules: Look for overcharge, short-circuit, and temperature protection, plus UL or ETL certification. For flights, stay below 100Wh, roughly 27,000mAh at 3.7 volts.
If you cannot have everything, prioritize usable capacity, then choose the smallest pack that meets your daily charging needs.
Frequently Asked Questions
How much capacity should an iPhone 8 Plus power bank have?
A 10,000mAh portable charger offers the best balance of size, weight, and charging capacity for an iPhone 8 Plus. Real-world output is lower than the printed rating, but this size typically provides about two full recharges, depending on cable and power loss. A 20,000mAh model suits travel or shared devices.
What should I look for in a charger for iPhone 8 Plus?
Look for a 10,000mAh battery pack with a USB-A or USB-C output, built-in safety controls, and enough power for at least 12W charging. The phone uses a Lightning cable, so confirm that the package includes one or that your existing cable fits. A charge-level display also helps prevent surprise low battery.
Can an iPhone 8 Plus use a wireless portable charger?
Yes, an iPhone 8 Plus can use a Qi-certified wireless battery pack, although wired charging is usually faster and more efficient. The phone supports the Qi standard, but it does not use MagSafe alignment. Choose a pad or pack rated for 7.5W, and remove thick cases if charging repeatedly stops.
Are small power banks enough for an iPhone 8 Plus?
Yes, a small 5,000mAh power bank can provide one useful recharge for an iPhone 8 Plus, but it offers less reserve than a 10,000mAh model. Its lighter size suits pockets and short outings. Check for at least 10W output, a Lightning cable, and a remaining-charge indicator before buying.
Conclusion
The Miady Mini Portable Charger 2-Pack is the top pick for iPhone 8 Plus owners who want two small backup batteries, one for a bag and one for home or work. If your priority is longer runtime between recharges, choose a larger-capacity single power bank instead, since it should provide more stored energy in one unit. Before buying, double-check each charger’s physical size, compatibility with your iPhone 8 Plus and charging cable, the number included in the package, and the current price, since listings and discounts can change. These compact chargers make the most sense for commutes, flights, and emergency top-ups, not heavy daily use when you need repeated full charges.
