Best 10000mAh Power Bank, and the Recalled Ones to Check

INIU’s Carry Slim is the 10,000mAh bank to buy, at about $25: 45W from either USB-C port, a USB-A port beside them, and 185 grams. The Anker Zolo is the bigger name with the cable built in, about $30 at 30W. On an iPhone that charges by magnet, the INIU SnapGo Compact is the cheapest 25W wireless bank we found, at about $45.

Oraimo and Xiaomi serve Nigeria and India better, selling locally at local prices, and both have their own section below.

Why you do not get 10,000mAh

The 10,000mAh on the box is what the cells hold, and not all of it reaches the phone. Anker’s own FAQ says 30% to 45% is lost in the cells and circuitry, so its 10,000mAh Zolo gives about 5,500 to 7,000mAh. Baseus says the same of its banks, and UGREEN and Xiaomi print a rated capacity of 5,600mAh on their 10,000mAh models. Belkin’s page says only that the amount delivered to your device is less than the 10,000mAh inside.

Anker and Baseus give the same rule of thumb: multiply the capacity by 0.65, then divide by your phone’s battery. For a phone with a 5,000mAh battery that is 6,500 divided by 5,000, or about 1.3 full charges. The makers’ claims for recent iPhones run from 1.5 to 2 charges, and Anker’s claim of up to two from the Zolo is worked out for an iPhone 15, whose battery Anker and Baseus both put under 4,000mAh.

If the phone itself is running down faster than it should, see what battery saver apps for Android can do before you buy anything.

Twelve banks by output, ports and weight

These are US store prices, rounded, with the marked-down price where a store had one. “Not stated” means the maker’s page gives no figure.

INIU’s two cheap 45W banks

The Carry Slim gives 45W from each USB-C port and 22.5W from the USB-A port, supports PD 3.0, PPS, Quick Charge 3.0, FCP and AFC, and recharges at up to 27W. INIU attaches a short cable as a lanyard, and the same store sells a version with the cable built in for about $27. INIU Carry Slim 45W on Amazon

The Pocket Rocket, about $33, is the smallest and lightest here at 160 grams, measuring 8.3 by 5.2 by 2.6cm, with a small display. INIU names PD 3.0, PPS and Quick Charge 3.0. The catch is a 20W input, so it refills more slowly than the Carry Slim. INIU Pocket Rocket 45W on Amazon

Cables that stay attached

Get the Anker Zolo. Its 5.4-inch USB-C cable is built in, and Anker gives 30W out and 20W in, though its page lists no weight. Anker Zolo 10K 30W on Amazon

Pay for the Anker Nano 10K 45W, about $60, only if you want 45W and a cable that retracts. It also has one USB-C and one USB-A port. Anker gives 45W from the cable or the USB-C port, 22.5W from USB-A and a 30W input, and with all three in use the total drops to 22.5W. It is also the bank we suggest among Pokémon GO accessories for a long walk, because the cable cannot be left at home. Anker Nano 10K 45W on Amazon

The Baseus EnerCore CR11, about $40, winds its 2ft USB-C cable back into the body, with 45W and a display. At 268 grams it weighs about 100 grams more than the INIU Pocket Rocket. Baseus EnerCore CR11 on Amazon

Belkin’s UltraCharge 10K with Integrated Cable and Display, about $45, has a braided 11.5-inch USB-C cable plus a USB-C port and a USB-A port, at up to 45W. Belkin’s plainer Power Bank 10K with Display was marked down to about $37, but it tops out at 20W. Belkin UltraCharge 10K on Amazon

The UGREEN Nexode Pro 10000mAh 45W has a built-in USB-C cable, 45W out, 35W in and a display. UGREEN’s page is thin on other detail, and at its list price of about $55 the INIU does the same job for less than half. At its marked-down $38 it is closer. UGREEN Nexode Pro 10000mAh on Amazon

Magnets for a MagSafe iPhone

These snap to the back of the phone. Anker says plainly that the magnets are meant for MagSafe iPhones, and that Samsung and Pixel phones generally need a magnetic Qi2 case to line up. By cable they charge any phone. The 25W wireless speed is narrower still: INIU says it applies only to the iPhone 16 and later running iOS 26, and not to the 16e or 17e.

The INIU SnapGo Compact wins on price, at about $45: Qi2.2 at 25W, a 45W USB-C port, a short attached cable and 190 grams. On paper it matches banks costing twice as much. INIU SnapGo Compact on Amazon

Where weight matters more than wireless speed, the Baseus PicoGo AM41, about $70, is 175 grams and 1.5cm thick, the lightest magnetic bank here that states a weight. It does Qi2 at 15W and 27W by cable. Baseus PicoGo AM41 on Amazon

Anker’s MagGo 10K Slim, about $80, is Qi2 certified at 15W, with 30W from its USB-C port and a 14.7mm body, and Anker says a full one delivers about 5,500 to 6,500mAh. Anker MagGo 10K Slim on Amazon

The UGREEN MagFlow 10000mAh 25W, about $90, does Qi2.2 at 25W and 30W by wire, with a built-in USB-C cable that doubles as a strap. It weighs 254 grams, against 175 for the Baseus. UGREEN MagFlow 25W on Amazon

Belkin’s UltraCharge Pro Slim Magnetic 10K, also about $90, does Qi2 at 25W and 30W from USB-C, with a 2ft cable in the box. Belkin gives no weight. Belkin UltraCharge Pro Slim Magnetic 10K on Amazon

Oraimo in Nigeria, Xiaomi in India

Oraimo’s own Nigerian store lists three wired 10,000mAh banks. For most phones, buy the Toast 22.5 Byte, at ₦17,800 against a list price of ₦19,800. It is 22.5W with two USB-A ports and one USB-C. The PowerFlow B11 has the same outputs at 15W, for ₦13,600 against ₦15,500. The PowerNova L11 is 22.5W with a built-in 29cm USB-C cable, at ₦23,900 against ₦27,000, and the extra ₦6,100 over the Toast mostly pays for the cable.

Xiaomi’s India store had the Power Bank 4i 10000mAh at ₹1,299, down from ₹2,499, the lowest price of its two. It is 22.5W with one USB-C and two USB-A ports, and heavy at 280 grams. The Pocket Power Bank 10000mAh is the one with the cable built in, at ₹1,499, down from ₹2,999, also 22.5W. Samsung India lists a 25W Powerbank 10000mAh with two ports at 210 grams, but its page showed no price, and we could not find it on Samsung’s US site.

Recalled power banks to check

Several makers have recalled power banks over a risk of overheating or fire. Find the model number printed on the back, bottom or side of yours. If it matches one of these, enter the serial number on the maker’s recall page before you use it again.

• Anker: the PowerCore 10000 (model A1263), sold in the US from 2016 to 2022, and five more models recalled worldwide in June 2025: A1257, A1647, A1652, A1681 and A1689. Two of those are 10,000mAh banks, the Power Bank 10K 22.5W (A1257) and the MagGo Power Bank 10,000mAh 7.5W (A1652). Only certain serial numbers are affected. Anker’s recall page has the checker.
• INIU: the BI-B41 10,000mAh in black or blue, sold on Amazon in the US between August 2021 and April 2022, with a serial number of 000G21, 000H21, 000I21 or 000L21. Details are on INIU’s recall notice.
• Baseus: the 65W 30,000mAh model BS-30KP365, and two 6,000mAh magnetic banks, PPCXM06 and PPCXW06. See Baseus’s recall page.
• Belkin: every unit of the BoostCharge Pro Fast Wireless Charger for Apple Watch + Power Bank 10K (BPD005), and the 20K power banks BPB002 and PB0003. Belkin keeps a list of its recalls.
• Xiaomi: its global site carries a recall notice for the Xiaomi 33W Power Bank 20000mAh (Integrated Cable).

Do not put a recalled bank in the household bin. Anker and INIU both say to take it to a hazardous waste site that accepts lithium batteries.

Taking one on a plane

A 10,000mAh bank is about 37Wh, the figure Xiaomi and Oraimo both print: Xiaomi lists its cells at 3.7V, and 10Ah times 3.7V is 37Wh. That is well under the usual 100Wh limit. The US aviation regulator, the FAA, says power banks must go in carry-on bags only, never in checked luggage, and that recalled batteries must not be carried at all.

The FAA also warns that airlines can be stricter. Emirates is one: it allows a single power bank under 100Wh, with its rating visible, kept out of the overhead bin, and it bans using or charging it on board. Check your own airline before you fly.
