# Nitecore UMS4 4-Slot Universal Battery Charger

The Nitecore UMS4 is a USB-powered universal charger listed for several rechargeable battery chemistries and sizes. Its four slots and automatic battery detection suit households or kit users with varied cells, but the listing gives inconsistent port and power-input details to verify before buying.

## Before you buy

- The listing is inconsistent about the charger’s layout and power details: the title and main details specify four ports and USB, while description wording says four ports and 3000mA but customer feedback identifies USB-C and mentions no quick-charge wall adapter. The title also gives dimensions in a different order and format from the detailed dimensions, and listed charging current and charge time are not tied to a stated test condition. Confirm the selected unit’s input connector, required power supply and applicable charging specifications before purchase.

## In the box

- 1 x UMS4 (Included)

## A good fit for

- People charging a mix of listed Li-ion-family and Ni-MH or Ni-Cd cells.
- Users who want a multi-slot charger with automatic battery detection and mode selection.

## Less suited to

- Buyers who need a confirmed USB-C connector or a supplied quick-charge wall adapter without checking the specific listing.
- Anyone requiring a guaranteed charge time across battery sizes, capacities or charging conditions.

## Customer feedback

Customer feedback highlights perceived build quality and fast charging, with some users also noting capacity for several cells, including a report of four 18650 batteries charging at 1 amp each. Feedback is mixed on the power source, reliability, battery tracking and charging performance. The listing’s multiple chemistry and four-slot claims provide useful context, but they do not resolve the reported variability or confirm the input connector and adapter situation.
- Positive themes: Customers describe the charger as good quality and appreciate its charging speed.
- Positive themes: Feedback notes the ability to charge several batteries, including a report of four 18650 cells at 1 amp each.
- Mixed feedback: Power-source feedback is mixed. Some appreciate USB-C power, while one comment says a quick-charge wall adapter is not supplied.
- Mixed feedback: Reliability, battery tracking and charging performance receive mixed feedback.

## Frequently asked questions

### Which battery types does the Nitecore UMS4 listing support?
It lists Li-ion, IMR, LiFePO4, Ni-MH and Ni-Cd rechargeable batteries, with a range of sizes including 18650, 21700, AA, C and D. Check that your exact cell is supported.
### Does the UMS4 have four charging slots?
The product details state four ports, and the description also says four ports. The listing’s power-input wording is less consistent, so confirm the physical connector and power supply requirements for the selected unit.
### Is a wall adapter included?
The explicit package list names only one UMS4. Customer feedback mentions that a quick-charge wall adapter may not be supplied, so do not assume one is included.
### Does it charge batteries in 55 minutes?
The listing gives a 55-minute battery charge-time figure but does not specify the battery size, capacity or charging conditions. Treat it as a listing claim, not a general charge-time guarantee.
