TL;DR: Anker MagGo packs more raw milliampere-hours than PETL — and that's worth saying plainly. But for everyday carry, raw capacity isn't the whole story. PETL's coin-slim circular aluminum build, native Apple Watch wireless charging, and cable-free snap-on convenience make it the better EDC power bank for most iPhone users. If you want a pocketable all-in-one for iPhone, Apple Watch, and AirPods, PETL wins. If you need a high-capacity reservoir for multi-day travel, Anker deserves a look.
Why Compare PETL vs Anker MagGo?
Search for "PETL vs Anker MagGo" and you'll find almost nothing — no independent head-to-head, no neutral third-party comparison. Anker dominates Amazon and review sites, and PETL is a direct-to-consumer brand that doesn't sell through Amazon at all. That gap in the conversation is exactly why this article exists.
Both brands make MagSafe-compatible battery packs that magnetically snap to the back of an iPhone 12 through iPhone 16. Both promise cable-free convenience. But they've made very different design decisions — and those decisions have real consequences for how the pack fits (or doesn't fit) into your daily life. Let's walk through them honestly.
What Is a MagSafe-Compatible Power Bank?
A MagSafe-compatible power bank uses a ring of magnets — aligned to Apple's MagSafe specification — to snap securely to the back of a compatible iPhone and deliver wireless charging without plugging in a cable. The standard originated with Apple and was later mirrored by the open Qi2 standard, which brings the same magnetic alignment to a broader range of devices. Both Anker MagGo and PETL use this magnetic snap-on approach.
The Honest Capacity Comparison
Let's get this out of the way first, because it's the most common question: Anker MagGo packs generally offer higher raw capacity than PETL. Anker's MagGo lineup spans a wide range of mAh options, and several models sit well above PETL's two offerings.
PETL offers two sizes: the original PETL at 3,000 mAh (up to 10 extra hours of talk time) and the PETL 2 Plus at 5,000 mAh (up to 15 extra hours of talk time). The 5,000 mAh PETL 2 Plus can deliver a near-full iPhone recharge for most current models. It is not a multi-day power station — and PETL is upfront about that.
If you're planning a three-day camping trip with no power access, or you're a filmmaker draining your iPhone shooting video all day, a higher-capacity Anker pack may serve you better on raw numbers alone. That's a legitimate use case, and we won't pretend otherwise.
But for the other 300+ days of the year — commuting, office days, errands, flights, gym sessions — most iPhone users need confident top-ups, not a power reservoir. That's the use case PETL is built for, and it's where the comparison gets interesting.
Design: Circular Aluminum vs Rectangular Plastic
This is where PETL and Anker MagGo diverge most sharply — and where your personal priorities matter most.
Anker MagGo packs follow the conventional approach: a rectangular slab, typically with a plastic or soft-touch finish. They're functional and well-engineered, but they look and feel like a gadget attached to your phone. The larger-capacity MagGo models add noticeable bulk and weight to your hand.
PETL took a different path entirely. It's the world's first circular MagSafe battery pack, CNC-machined from aluminum with a tempered glass top. At 70mm wide and just 14mm thin (the original PETL) or 72.5mm wide and 16.2mm thin (the PETL 2 Plus), it's coin-slim and genuinely pocketable. The circular form factor isn't just aesthetic — it means the pack never fights the natural way you hold your phone. It disappears into your grip.
The aluminum-and-glass construction also puts PETL in a different material category from most competitors. It feels premium in a way that's closer to an Apple product than a generic accessory. Colors like Cosmic Orange, Slate, Blush Gold, Sahara Gold, and Natural anodized aluminum are finished to a standard you'd associate with a piece of jewelry or a high-end phone case — not a utility gadget you tolerate in your bag.
PETL is designed to be something you choose, not something you settle for.
Does Anker MagGo Charge Apple Watch?
This is one of the most searched questions in the category — and the honest answer is: no, Anker MagGo packs do not natively support Apple Watch wireless charging.
Apple Watch uses its own proprietary magnetic charging protocol. Standard Qi or Qi2 wireless output does not power it. To charge an Apple Watch from a power bank, the pack needs a dedicated Apple Watch charging module built in — and Anker's MagGo lineup does not include one.
PETL does. Both the original PETL and the PETL 2 Plus can wirelessly charge your iPhone, Apple Watch, and AirPods — all from a single disc, with no cables, no apps, and no setup. For anyone in the Apple ecosystem carrying all three devices daily, this is a significant practical difference. PETL replaces a tangle of cables and adapters with one pocketable puck.
Heat Management: Circular Alignment vs High-Wattage Output
Heat is the enemy of battery longevity — both in your power bank and in your iPhone. It's worth being specific here.
Some higher-wattage MagGo models (particularly those offering 25W output) use active cooling to manage the thermal load that comes with pushing that much power wirelessly. Active cooling adds engineering complexity and, in some form factors, bulk.
PETL's circular design minimizes a different source of heat: coil misalignment. When a wireless charger's coil drifts out of alignment with your iPhone's receiver, energy is wasted as heat rather than delivered as charge. PETL's perfectly centered circular geometry keeps the coil locked in place every time it snaps on, maximizing energy transfer efficiency and keeping the pack running cool during normal use. The N52 neodymium magnets provide a strong, consistent hold that resists drift even when you're moving around.
PETL supports 15W Qi wireless charging on the PETL 2 Plus — fast enough for real-world top-ups without the thermal challenges that come with pushing significantly higher wattage in a pocketable form factor.
iOS Integration: Battery Widget Support
Both PETL and Anker MagGo packs show up in the iOS battery widget when attached to an iPhone — so you can see your pack's charge level at a glance without opening an app. No Bluetooth pairing, no proprietary app required. This is standard behavior for quality MagSafe-compatible packs and a feature worth confirming when buying any wireless power bank.
Where to Buy: Amazon vs Direct
Anker MagGo is widely available on Amazon, at Best Buy, and through other major retailers. That convenience is real, and for some buyers it matters — fast Prime shipping, easy returns, a familiar checkout.
PETL is sold exclusively direct-to-consumer at gopetl.com. There's no Amazon listing, no retail markup, and no middleman. Shipping is free on U.S. orders over $129, and PETL offers a straightforward $5 return label if you need to send anything back.
Buying direct also means you're getting the product as the brand intended it — at the correct price, with full warranty support, and without the risk of grey-market or counterfeit units that occasionally surface on large third-party marketplaces. For a premium aluminum-and-glass product like PETL, that assurance matters.

Who Should Buy PETL?
PETL is the right MagSafe power bank if you:
- Carry an iPhone, Apple Watch, and AirPods every day and want one pack to charge all three
- Want something slim enough to slide into a jeans pocket or a small bag without thinking about it
- Care about how your accessories look and feel — not just what they do
- Want to buy direct with clear pricing and no Amazon markup
- Need reliable top-ups through a workday, commute, or weekend trip
PETL is not the right choice if you need maximum capacity for multi-day off-grid use, or if you refuse to buy from any store that isn't Amazon. Those are real preferences, and there are products built for them.
Who Should Buy Anker MagGo?
Anker MagGo makes sense if you:
- Need the highest possible mAh capacity in a MagSafe form factor
- Don't need to wirelessly charge an Apple Watch from your power bank
- Strongly prefer Amazon for purchasing and returns
- Are a heavy power user who drains a full iPhone more than once in a day
The Bottom Line: PETL vs Anker MagGo
The best MagSafe power bank isn't the one with the most mAh on the spec sheet — it's the one you'll actually carry every day. Anker MagGo is a solid, well-known option with capacity advantages that are real and worth acknowledging.
But PETL is genuinely different: a circular, aluminum-and-glass power bank that charges your iPhone, Apple Watch, and AirPods from a single pocketable disc — at a price that's fair and a design that feels like a deliberate choice rather than a compromise. For the vast majority of iPhone users who need confident, daily top-ups without carrying a brick, PETL is the clear EDC winner.
